THE VENERABLE HALF-STACK
MAY BE AN ANACHRONISM IN TODAY’S
world where seemingly everything is being downsized, but there’s
still plenty
of life
left in a scrappy, head-plus-4x12 rig. The amps on deck for this roundup are
tube pow-
ered and predominantly in the 50- to 100-watt class. Most have
channel-switching
capability, and nearly all (exceptions being the Acoustic, Carvin and PRS
heads) are
still big lugs to carry around. Understood, there’s no easy way to
make a
lightweight
tube head in this power range, but an amp that weighs around 50 lbs paired with
a
cab that clocks in at twice that amount does not make for a pleasant trip up
the stairs
or around the block.
We’ve evaluated these amps purely on their sonic performance
and
features, seek-
ing to find that righteous balance of form and function that yields the best
tones with
the least amount of effort. Tests were done using Fender Strats and Teles,
Gibson Les
Pauls and SGs, a PRS Quatro and Modern Eagle, and a smattering of guitars from
custom builders. All the amps were auditioned with 4x12 cabinets supplied by
the
manufacturers. — ART THOMPSON
Acoustic GT50H
THE GT50H IS A TWO-CHANNEL
amp with several nice twists, including a
choice of Triode and Pentode output tube
modes for two very different sounds, and a
Half Power switch that interacts with the
Triode/Pentode switch to provide between
12.5 and 50 watts, making the amp adapt-
able to a variety of both rehearsal and per-
formance situations. The Clean and Lead
channels share a single input that is switch-
able between Normal and Bright and a single
set of tone controls, which potentially limits
the amp’s tone-shaping capabilities, but in
practice didn’t prove to be a major liabil-
ity, thanks mostly to the way in which the
Bass, Middle, and Treble controls are voiced.
An included 4-button footswitch lets
you toggle between channels, turn the
Accutronics spring reverb on and off, and
engage both the High Gain and variable
Boost functions. The ability to switch to
High Gain while using either the Clean or
Lead channels effectively results in four
distinct and directly accessible tones. The
variable Boost theoretically gooses either
channel’s signal by up to 15dB, but even
when maxed the actual volume increase
was relatively subtle. There’s also an effects
loop with a handy dry/wet Mix control.
Acoustic recommends that the GT50H
be paired with the matching G412AC
speaker cabinet, which contains four Celes-
tion G12P80s and sports dual inputs con-
figurable for mono (4 Ω or 16Ω) or stereo
(8Ω per side) operation. The cab sounded great in mono at16Ω,
delivering a
nicely bal-
anced blend of clear highs, punchy mids,
and firm lows—and its metal handles and
casters added to an overall impression of
sturdiness.
The GT50H sounded significantly dif-
ferent when paired with a Stratocaster than
it did with a Les Paul Standard. I generally
preferred the former, as the tones were
clearer, livelier, and had a warmer low end,
though the ’59 reissue Paul also produced
a range of very nice sounds, particularly
when using the bridge pickup on higher-
gain settings. Generally, there was a dra-
matic difference between the two output
modes. As might be expected, Triode Mode
produced a smoother, rounder, and darker
sound compared with the more aggressive
edginess imparted by Pentode Mode. Per-
sonally, the former appealed to me most,
and while hard rock, punk, and metal gui-
tarists may differ, I even found that palm-
muted low-note riffs sounded tighter and
punchier in Triode mode. Also, while the
Lead channel dished up some tasty over-
drive sounds, I got the best old-school
British-style crunch by cranking the Clean
Volume control, and punching things up
another level by switching in High Gain
when appropriate.
Considering its clean headroom, versa-
tile overdrive and distortion capabilities,
and useful features, the GT50H is a good
general-purpose amp at a reasonable price.

Blackstar S1-1046L6
BLACKSTAR IS MAKING A NAME FOR
itself with a series of amps that offer a lot
of bang for the buck through the common
dual-sourcing practice of being designed in
the U.K. and manufactured offshore. Sev-
eral smaller models have won respectable
followings, but larger amps such as the
S1-1046L6 seek to put that value and flexi-
bility into a seriously powerful package for
the big-stage rocker. The head is derived
from the company’s premier Series One
line, which also features an EL34-powered
version voiced specifically for those tubes.
The S1-1046L6 carries the more American-
toned bottles, is voiced to appeal more to
the modern high-gain metal player, and car-
ries a dizzying array of features.
Four footswitchable channels offer
Clean, Crunch, OD1, and OD2, with
independent Gain and Volume for each,
and two three-knob tone stacks shared
between the first and second pairs of chan -
nels, each of which also has a dedicated
ISF control. This proprietary “Infinite
Shape Feature,” takes you toward Amer-
ican tube-amp voicings when rolled coun-
ter-clockwise, and British voicings when
turned clockwise, exponentially increas-
ing the tweakability of each EQ section.
Beyond the shared Presence, Resonance,
and Master Volume controls, there’s also a
Dynamic Power Reduction (DPR) control
that governs overall output by reigning in
the output and output driver tubes’ voltage
levels, from ten to 100 percent. An added
Bright/Warm switch on the Clean channel
and Super Crunch on the Crunch ups the
options there, while a plethora of back-panel connectivity—including
level-switchable
FX loop, Speaker Emulated Output with
XLR and 1/4" outs, and MIDI switching
capabilities—boost the S1-1046L6 right
into the realm of high-concept amplifica -
tion. It’s all extremely well thought-out,
and feels robustly put together, although it
can be difficult to see how the Clean/Warm
and Super Crunch switches are set if you
aren’t using MIDI switching. The Series
One 412A is a rugged, closed-back, over-
sized cab made from finger-jointed birch
ply and enclosing four Celestion Vintage
30 speakers wired for 4Ω, or 16Ω when
used in mono or dual 8Ω pairs.
The S1-1046L6 delivers a helluva’ lot
of oomph for the player seeking ultimate
flexibility, and sounds extremely good
wherever you point the dial. Given the
bountiful features you can’t expect bou-
tique-single-channel quality from every
voice, and yet every setting I cooked up
(with either a Grosh Set Neck or Fender
Strat injected) proved so bold, dynamic,
and satisfying that I was left wanting for
nothing. Cleans are sweeter and chimier
than the “rhythm” options on most old-
school channel switchers, Crunch is meaty
and bold, and the OD channels, between
them (and their shared EQ options), take
you from gut-busting brutal to über-satu-
rated shred-wail with myriad nuances in
between. To top it all off, the DPR works
great to rein in output in smaller rooms
or venues. The back-panel functions work
just as they should, too, making this amp
a real heavy hitter in the connectivity and
switchability stakes. — DAVE HUNTER
Carvin Legacy 3
THE LATEST EVOLUTION OF THE
Legacy Series amps designed in conjunc-
tion with Steve Vai, the Legacy 3 features
the same channels 1 and 2 of the original
model, but has a reconfigured channel 3
with controls for Drive, Volume, and Pres-
ence, plus a Gain switch. Channels 2 and 3
share a common set of tone controls, and
are selected by buttons in the center of the
front panel, with the optional FS44M foot-
switch ($44), or by MIDI. Green, yellow,
and red LEDs indicate the active channel,
and the interior lights up in these colors
as well. Slightly confusing is that channel
3 (which has the most gain potential) illu-
minates in yellow while channel 2 is red,
but you can re-program the LEDs in any
combination you want via MIDI.
Getting around on the Legacy 3 is easy
enough once you get used to how channel
3’s controls are arranged. This amp has
one of the most headroom-minded clean
channels in existence. Channel 1 has a nice
balance of crispness and body, and sounds
great for pristine chording and fingerpick -
ing. But this preamp doesn’t distort, so
you either have to turn the volume up high
enough to encourage some clipping in the
power stage—more practical when using
the 15-watt setting due to how fiercely
loud this amp gets in the 50- or 100-watt
modes—or use an overdrive pedal. The DSP
reverb adds welcome ambience and air to
the clean tones, enhancing the sense of
dimension with warm, spacious, and nat-
ural-sounding reflections.
Engaging channel 2 brings on a rush
of distortion even at the lowest Drive set-
tings, so it’s kind of a straight shot to sus-
tainville, rather than a more scenic journey
between clean and overdriven sounds.
The dynamic response of this channel is
such that you can get milder overdrive by
turning down your guitar (or by using a
Volume setting of around 8 with the Drive
set low), but the Legacy 3 is definitely best
suited for players who want very thick ’n’
sustaining rhythm and lead sounds, and
then be able to switch to a stratospheric
level of distortion for solos. The variable
boost function is very useful when using
the high distortion this amp is capable
of, as it lets you preset just enough level
increase to ensure your tones will punch
through clearly no matter how much sat-
urated grind you’re pushing. The shared
EQ posed no problems for dialing up tones
on channels 2 and 3, though having a sep-
arate Presence control on the third chan-
nel makes it easier to get the definition
where it needs to be with humbucker gui-
tars—especially when the Gain switch is
on and the preamp is pouring out a mon-
soon of distortion.
Very adept at delivering extremely clean
and viciously distorted tones, the Legacy
3 is a great choice for players who want a
palette of super-sustaining tube sounds,
but who also need a channel that is opti-
mized for guitars, pedals, or anything else
that warrants no distortion from the amp.

Egnater Armageddon
BRUCE EGNATER’S AMPS HAVE
always been a tone-shaper’s dream, and
with its glut of mini-switches, knobs, and
a dense, feature-laden rear panel—not to
mention a 7-button floorboard that even
sports mini toggles for the footswitches(!)—
the Armageddon promises even more of the
same for the tweaker crowd. Admittedly,
I was a bit daunted at first by the Arma -
geddon, an amp that is, after all, named
after an end-of-the-world scenario. But I
quickly discovered that it is super-easy to
get around on, and every one of those func-
tions served a useful purpose.
Running my Telecaster on the amp’s
clean channel, I was greeted with some
tasty multi-dimensional tones that offered
great touch-sensitivity and musicality. The
Gain control on the clean channel definitely
helps dial in how much caloric content you
want in your clean tone, which is always a
welcome ability. Channel 2 conjured some
magical hot-rodded tones in the classic
modded-Marshall vein, with tight snarling
mids, pummeling bass, and a searing top
that begs for humbuckers. There’s a good
range of frothy gain on tap, and you can
voice this channel to be a Keef-on-steroids
grinder or a modern metal machine. Best
of all, no matter what you dial up, these
tones react well to your touch, cleaning up
wonderfully with a lighter attack. The amp’s
digital reverb, which sports individual level controls for each channel, works
wonders
for adding air and ambience to clean tones
and lead lines. And once you have tailored
it to your style and guitar, it sounds consis-
tent at whatever volume you’re playing at.
You might think that Channel 3 is where
the Armageddon makes good on its moni-
ker. Well, it can, but actually Channel 2 and
3 not only share EQ, they are identical in
every way, so it’s up to you to set them up
differently, and that’s where all of Egnater’s
tweaking options shine. The Tight, Bright,
and Gain switches on each channel are voiced
wonderfully, allowing just the right touch
of overall seasoning once you’re done dial-
ing in the EQ. If you want to slim out your
rhythm sound a touch or add that last bit
of bite or midrange heft to your lead tones,
the Armageddon can do it. The high-gain
sounds are never hyped sounding, and the
EQ is very natural with enough range to
easily accommodate humbuckers or single-
coils. The bypassable Midrange section with
its Depth and Level controls is the bomb for
scooped metal sounds, and coupled with
the variable ISP Decimator noise gate, you
can get ridiculously tight, chugging tones
that track your picking like a bloodhound!
Bottom line: If you are dedicated to micro-
managing your tones, and also dedicated
to delivering them in high-volume situa-
tions, the Armageddon may be the end of
the world for you. — DARRIN FOX
Fuchs Mantis 100
DELIVERING A STOUT 100 WATTS
from four EL34s (6550s or KT88s optional),
the Mantis 100 nails contemporary rock and
metal tones in two distinct, footswitchable
preamp channels. Channel 1 shoots for
“hot-rodded American,” with a clear voice
and an aggressive midrange, while Channel
2 is probably best described as “California
grind,” with a scooped voice and thump-
ing lows, something we might have called
“modded British” in the past. Each channel
has its own Gain and Master control and
independent 3-band tone stack, and they
share global Master, Thrust (low-end reso-
nance), and Presence controls. Round back,
there’s a half-power switch which cuts two
EL34s, outputs for 4Ω, 8Ω, and 16Ω speaker
cabs, and a series effects loop with a hard-
wire bypass switch and a signal-level selector.
The Mantis’s circuit is hand-loaded
onto a heavy duty PCB within an aircraft-
grade T-6 aluminum chassis with stain-
less steel hardware throughout, and uses
careful grounding and DC-heated preamp
tubes to keep noise at a minimum. Both
the power and output transformers are
custom-wound and over-spec, and the
amp includes a cooling fan to extend tube
life. In short, it appears built to get the job
done, and its use by a growing list of tour-
ing rock artists seems a testament to that
impression. The Fuchs 412 cab is a tradi-
tional heavy-duty closed-back design, made
from strong North American-grown, low-
emissions “Lite-Ply” plywood, with four Eminence Wizard
speakers
inside.
Played with a Grosh Set Neck and a
Fender Strat, the Mantis delivered might-
ily on its premise. This amp simply isn’t
designed for “classic” tube-amp tones—
blackface Fender-esque clean or vintage-
Marshall crunch just aren’t its forte, and
aren’t meant to be. It excels at taking you
straight to that big chug and shred, with a
minimum of fuss and fiddle at the control
panel. In fact, just a few minutes with the
Mantis reminded me what an integral part
of the “inspiration chain” the right amp can
be: however much I tried to throw roots,
blues-rock, or indie-pop riffs its way, the
Mantis spit me out the other side churning
21st century shred and death-metal licks,
and having a blast with it.
Channel 1 accesses your best clean tones,
but with the channel Master advanced it
gets loud fast—exponentially more so than
channel 2, even with the global Master
reined in. I found channel 1 worked best,
therefore, at clear-voiced semi-grind and
moderate lead tones, where it proved sweet
and dynamic, with bags of overtone-laden
shimmer. Channel Two goes straight to
scooped metal, and thumps like a beast
in the process. This one is impressive in
its easy path to gut-kicking power-chord
rumble, and will get you head banging in
no time flat. With more than enough gain
on tap for most needs, the Mantis 100 is
an extremely worthy package for today’s
road rocker. — DAVE HUNTER
Hughes & Kettner TriAmp
MKII
THE ALEX LIFESON SIGNATURE
Edition Series TriAmp features three inde-
pendent channels, each with a secondary
mode that can be selected via front-panel
switches (labeled Gain A, Gain B) or the
included stageboard. This effectively makes
the TriAmp a six-channel amp with each
pair of channels sharing a common set of
tone controls. Not surprisingly, the TriAmp
covers a lot of sonic ground. The clean chan-
nel (Amp 1) with Gain A selected offers
crisp, Fender-voiced tones that exude bright
top-end, warm mids, and a burly set of lows.
This channel stays nice and clean even with
the gain turned up, and as there’s no Master
Volume, it’s a natural for big, ringing chords
and twangy country picking. Switching to
Gain B reconfigures the circuitry to evoke
a Vox-style response with added sparkle in
the highs and enhanced midrange complex-
ity. The bottom-end can get a little tubby
in this mode, but you can remedy that by
pressing the Amp 1 Tight switch, which
revoices the low frequencies in a manner
that makes it easy to forget you’re playing
a half-stack and not an AC30 combo! This
channel sounds killer for rhythm playing
when turned up, and the well-implemented
Master Volume also makes it possible to
crank the snot of it for heavier rhythm and
lead tones while retaining an excellent sense
of mass and tonal balance at lower levels.
Amp 2 is the go-to channel for Marshall-
style tones, which pack a punchy, aggres-
sive, but not too overdriven response with
Gain A selected. It’s close to a JCM 800
kind of tone, but the H&K version has a slightly harder edge when
pushing
lots of
drive. The dynamic response is very good,
and this mode could be a great match for
smoother sounding overdrive pedals when
combined with a lower gain setting on the
amp. Selecting Gain B unlocks a broader
range of overdrive, allowing for everything
from juicy, early Clapton-style “Blues-
breakers” tones to torrents of grind that
can evoke super-sustaining Gary Moore
lead sounds.
For pure aggression, Amp 3 fills the bill
with a super-quick attack and a definition
that brings out the stringiness in chords
and allows speedy single-note runs to cut
though a mix like a knife. There’s massive
harmonic action going on here when Gain
A is turned up halfway or higher, yet the
dense distortion never leads to mushy or
indistinct tones. The brutal response of
this channel works particularly well with
Gain B selected, which significantly ups
ante for metal by virtue of a fuzzier, gnar-
lier distortion tone and a tight bottom-end
chunk. Despite having some excess hum
(most likely a preamp tube issue), Amp 3’s
insane gain and ability to extract equally
punishing tones from humbuckers or sin-
gle-coils makes it a great platform for mas-
sive, modern-style overdrive tones.
One of the world’s most visually allur-
ing amplifiers with its clear, illuminated
front panel, chrome-plated chassis, and
lighted pushbuttons, the TriAmp MKII
is an impressive affair for rock and metal
players who worship at the altar of gain.

Mesa/Boogie Royal Atlantic
THE ROYAL ATLANTIC APPEARS
to be a straightforward 100-watt amp with
two channels and a footswitchable high-
gain mode. However, a unique feature is
its channel-assignable Multi-Soak attenua-
tion system that offers three attenuator cir-
cuits that can be used to varying degrees
on all channels. Powered by four EL34s
(a bias selector on the rear panel makes it
easy to swap in 6L6s), this British-voiced
amp is designed for players who appreciate
how power tubes contribute to tone when
pushed hard. As a standup 100-watter (50
watts in half-power mode), the Royal Atlan-
tic delivers outstanding clean tones with
tons of headroom, meaty crunch textures,
and furious shred tones with gobs of touch-
responsive sustain. When the gig demands
less volume you can, of course, throttle
things back using the Master Volume con-
trol on the Clean channel or the indepen-
dent Masters on the Lo/Hi channel. But the
Royal also lets you reduce volume while
keeping the tubes at a boil via its three
Multi-Soak rotary switches on the back
panel. Each 5-position Multi-Soak control
has detents for Bypass, -4dB, -8dB, -12dB,
and -16db of wattage reduction. The latter
setting cuts the amp’s maximum power
down to about 3 watts, which is a huge
amount of attenuation to deploy when the
rest of the amp is cooking at full bore in
100-watt mode. The potential downside is
that running the power stage near full-tilt
when using extreme attenuation settings
(-12db, -16dB) causes the tubes to work
much harder and generate more heat, thus
reducing life expectancy. Very high attenu-
ation settings can also cause the sound and
feel to become somewhat less defined and
squishy. I found the -4db and -8db posi-
tion to be most useful on the Hi/Lo chan-
nel for getting aggressive crunch rhythm
and soaring lead tones that maintained the
girthy feel of tubes flexing their muscles.
The Royal’s Clean channel transitions
beautifully into distortion with detailed
highs and lots of upper midrange com-
plexity when Gain is turned up. The tube-
driven spring reverb circuit delivers a
lush and expansive sound. Reverb level is
adjustable from the rear panel only, but
this inconvenience is offset by a 3-position
switch that (A) assigns the reverb equally
to all the channels, or (B) defeats it when
switching to Hi/Lo, or (C) defeats it just
in Hi mode. Worth noting, too, is that the
series effects loop is completely bypassed
when nothing is plugged into the send or
return jacks.
Well equipped for anything from fusion
to country to hard rock and metal, the
Royal Atlantic plays well with humbucker
or single-coil guitars and has enough head-
room, sustain, and volume control to make
it workable for venues of virtually any size.
If you’re looking for a high-power tube amp
that can pretty much do it all, the Royal
Atlantic is definitely an amp to audition. — ART THOMPSON
Orange OR50
ORANGE WAS FOUNDED IN ’60S-ERA
swinging London by musician and wan-
nabe producer Cliff Cooper as a veritable
musical empire. The storefront on New
Compton Street originally encompassed
music publishing, a record label, a record-
ing studio, and an agency, and when these
proved slow to turn a profit, Cooper dis -
covered a demand for loud amplifiers. The
OR50H was inspired by Orange’s origi-
nal flagship, the “Graphic Overdrive” line,
which represented its control functions in
picture form only. For the uninitiated, the
legends on the amp’s front panel represent
(left to right)—Gain, Bass, Middle, Treble, HF Drive, and Master
Volume. The
penul-
timate of these is a nifty little “two in one”
control. Turning it clockwise increases
power-amp presence, while also ramping
up power-amp gain. Finally, there’s a front-
panel jack for a single-button footswitch to
hop between your preset Master Volume
level, and full output.
Build quality of the OR50H is probably
best described as “robust contemporary.” A
sturdy PCB is loaded with many good-qual-
ity, western-made components—if not the
most high-end bits and pieces—and accom-
panied by heavy British-made transform-
ers. Tube sockets are all reinforced to the
chassis itself for long wear and reliability.
Orange speaker cabs are as distinctive as
the company’s amp heads, and the PPC412
is no exception. The closed-back cab is rug-
gedly constructed of heavy-duty plywood,
with a woven-cane front grille protecting
four Celestion Vintage 30 drivers.
Plugging into the OR50H is like hop-
ping a time machine to the late-’60s and
early-’70s, when the classic Brit-rock tone
was segueing from crunch to, well, more
crunch. With the gain just shy of half way, the amp will do plenty of
Marshall-esque
tricks, giving me Kossoff or Page with my
Grosh’s humbuckers, or Hendrix with my
Strat. To hit the Orange in its wheelhouse,
though, wind it up to around one o’clock,
where it dishes out a bombastic, chunky
pre-metal thump with a delectable mid-
range grind. Despite the master volume
and the footswitching function (which is
really only much good if you want a solo
boost equitable to the master’s full-out set-
ting), this is actually old-school rocking—
find your desired lead tone, then do what
you can to obtain a pseudo-clean from the
guitar’s volume control, which, fortunately,
works extremely well.
The deceptively simple preamp features
three gain stages, so the OR50H gets juicy
and sizzly fast, and chances are you’ll just
want to solo all night. From noon to full-
blast, the Gain control doesn’t add much
more apparent volume (that’s easily gov-
erned by the Master), but piles on the sat-
uration, adding harmonic richness, sustain,
and willing feedback to the brew. The HF
Drive knob is a real hidden weapon, and
while either end of the dial is rather muted
or spikey, respectively, many great shades
lurk in the eight o’clock to four o’clock
range, taking you from woody and warm
to crispy and biting. Given its simplic-
ity, the OR50H is surprisingly versatile,
and has a seductive, “play-all-day” feel
that always leaves me yearning for more.
— DAVE HUNTER
Peavey Triple XXX II
WHEN PEAVEY INTRODUCED THE
5150 amplifier (now known as the 6505)
in 1992, the Mississippi-based company
suddenly found itself the choice de rigueur
amongst players and producers looking for
the most savage, punishing metal tones on
the planet. As the years wore on, Peavey
has continued adding to its line of aggres-
sive tone machines, and its latest, the
Triple XXX II, keeps the hits coming. With
a Gibson Les Paul and a Fender Telecaster,
I put the Triple XXX through the paces,
starting with the amp’s formidable Clean
channel. This amp is easy to use, but it’s
worth noting the 3-button footswitch is
arranged so that the Clean channel has to
be bypassed in order to activate the Lead or
Rhythm channels. So, for example, if you
want to go straight from pristine clean to
shred scream, you need to make sure that
the Lead channel is pre-selected.
With humbuckers, the Triple XXX’s
clean tone is beefy—real beefy—with a thick
midrange and huge bottom end response.
Thankfully, there is enough treble sheen
so that chords can ring with enough bril-
liance to render chimey arppegiations or
funk stabs authentic. With single-coils,
the clean tones are very easy to dial up
as there is a ton of detailed sparkle on
tap—as well as a boatload of clean head-
room—big and bold for sure. Switching to
the Rhythm channel, my mild-mannered
Telecaster was quickly elevated to a shred
machine with the blessing of the channel’s
aggressive, ultra-high-gain tones. Turn-
ing the Gain way down gave some nice
toothy definition to power chords and
chugging, low-string riffs—always with
a dash of agro attitude. It’s these types
of tones that the Triple XXX does best:
crunch like a punch to the face. The Lead
channel gives you an opportunity to shoot
for the stars with a seemingly unlimited
supply of distortion. Even when pushed
to the hilt, the Triple XXX’s bass response
stays tight and focused while delivering a
punishing amount of heft. In conjunction
with the master Presence and Resonance
controls, the Fat switch on the Lead and
Rhythm channels is your ticket to either
hot-rodded Marshall or Boogie Rectifier
shades, especially with humbuckers. The
amp’s EQ is extremely responsive, giving
you everything you could need with the
twist of a knob, and in all other regards,
the Triple XXX is powerful sonic machine
that delivers bone-rattling rock and metal
tones that are as intense as they are prac-
tical. — DARRIN FOX
PRS Core Series 2 Channel
“H”
THIS LATEST VERSION OF THE 2
Channel amplifier that PRS introduced in
2010 is powered by a pair of 6L6s and fea-
tures proprietary Heyboer transformers. It
also wears the new charcoal maple fascia,
which is now standard on all Core series
amplifiers. The control layout remains
unchanged, however, with two independent
footswitchable channels, Clean and Lead
Master Volumes, and a Reverb control that
affects both channels. Fired up through a
PRS 4x12 loaded with Celestion Vintage 30
speakers, the 2 Channel chalked up some
very sweet Fender- and Marshall-flavored
tones—thanks to the abundant range of the
well-voiced passive tone controls on each
channel. The wide gain range of the Clean
channel makes it possible to get everything
from super clean tones to gutsy overdriven
textures. The spring reverb sounds excel-
lent, and through the closed-back 4x12, the
amp’s tones are surprisingly open and spa-
cious. As with any amplifier, the voicing of
the tone controls is hugely important, and
the cool thing here is that the 2 Channel’s
tone stack has both the ability to provide
useable sounds pretty much wherever the
knobs are set, yet is also extremely effective
for tone shaping. Need to shave off some
low end (there’s a lot on this channel) and/
or get a little more crispy detail when using
a humbucker guitar—or perhaps just beef
up the sound of your Strat’s single-coils—
these are easy tweaks with this amp.
Switching to the Lead channel brings on a
ballsier overdrive response that’s a bit leaner
in the lows but otherwise very consistent
with what the Clean channel presents. This
makes for seamless switching from clean into
a blaze of distortion, and the Lead channel’s
dynamic sensitivity also makes it possible to
simply dial up a great tone for soloing and use
your guitar’s volume knob to surf between
rhythm and lead. Lower settings of the Volume
knob yield tones that are reminiscent of Mar-
shall’s “plexi” era, and with the Master turned
up enough to let the power tubes trot into
overdrive, it’s easy to catch a whiff of early
Clapton. Inching toward the halfway on the
Volume control provides sweet, sustaining
tones that invite Duane Allman-style blues
licks, while some further advancing on the
Volume brings you to a scorching overdrive
zone with the twanginess and stringy clarity
heard in David Grissom’s fiery tones. The
scope of the Lead channel can also accom-
modate metal and shred. Dialing down the
well-implemented Master lets you enjoy what
this amp can do at more sensible volumes,
and without destroying the balance or feel—a
good thing, considering no power reduction
feature is provided.
The 2 Channel “H” is a no frills amp
that’s
ideal for players who just want killer clean
and overdrive tones. This compact head is
nicely priced for a U.S.-made product, it’s
ruggedly built, and it won’t bust your knuck-
les to carry. — ART THOMPSON
Traynor YSC100H2
FOR YEARS PLAYERS HAVE BEEN
snatching up vintage EL34-loaded Traynor
Bass Master heads, noting that they weren’t
a far cry from classics from across the pond,
and modding them to Marshall specs. The
YSC100H2 builds on Traynor’s EL34-fired
roots and twists them into a contemporary-
styled head that offers about as much as
any modern player could ask from a rig.
At the front end, the YSC100H2 has three
fully independent channels with their own
Gain, Volume, and EQ controls, and indi-
vidual Reverb and Effects level controls
(return-level mix) that remember their set-
tings even as you switch between channels.
Pushbutton switches for Modern/Vintage
and Scooped (Bright on channel 3) increase
the voicing options on each channel, while
there are also individual footswitchable
Boost settings on each to jump up the gain
as desired, and a pre-settable Solo Boost
control in the master section.
There’s a wealth of features ’round back,
too. Among these are two efects loops—
a parallel loop with Level control and Pre-
Out/Amp-In jacks for series looping—and
outs for speaker-compensated DI on XLR
and headphones on a 1/4" stereo jack. An
“Amplifier Mode” switch lets you select
between 100 watts in A/B mode, or 30 watts
in Class A (fixed bias, with two EL34s cut
from the circuit) The power switch simply
reduces the plate voltage from 500 volts
to 250 volts and then re-biases.. The only
hint of inflexibility in this rugged and well-
thought-out amp is its relative paucity of speaker-out options: an impedance
switch
beside the dual outs allows a 4Ω or 8Ω load
at 100 watts, or 2Ω or 4Ω at 30 watts, which
might limit some speaker cab options. The
accompanying YSC412A2 is a traditional
angle-toped, closed-back cab made from
rugged birch ply, with four Celestion Vin-
tage 30 speakers wired for either 4Ω or 16Ω
mono, or two 8Ω stereo pairs.
The YSC100H2 is a heavily feature-laden
amp that seeks to do a little of everything
for the contemporary rocker. The func-
tionality and flexibility are impressive,
and everything works as it should. Cleans
are accessed in channel 3, which is woody
and full with plenty of headroom, if not
overly inspiring in its harmonic content.
Channel 2 runs from balanced crunch to
contemporary lead, and arguably offers
the YSC100H2’s most versatile all-round
voice. Channel 1 is heavily predisposed
toward metal, with a hyped low-end thump
that kicks hard in the gut, and remains
in evidence at all EQ settings. Given the
truly independent EQ on each channel,
plus Boost, Modern, and Scoop buttons
(Bright on channel 3), and the independent
Reverb and Effects level controls, it’s easy
to craft each voice to your requirements,
and from girthy power-chord rhythm to
singing lead, the YSC100H2 covers all the
modern-rock bases confidently. If some of
the amp’s tones feel a tad processed and
pre-packaged, Traynor, at this price range,
still gives good value in features and ver-
satility. — DAVE HUNTER
