I HAVE ALWAYS ASSOCIATED MESA/BOOGIE WITH AMP TONES
that are either super clean or soaked in gobs of gain. In the last couple
of years, the company has released several amps that have dismantled
that perception one model at a time. With the release of the TA-15,
Mesa became an honorable contender in the world of British-toned
amplifiers. Continuing further down this path across the pond, Mesa/
Boogie recently introduced a new member to the Transatlantic family,
the TA-30. At first glance, this amp appears to just be a higher-powered
version of the TA-15, but upon closer investigation, the TA-30
has several new features, which include a series effects loop, an alltube
spring reverb with separate mix controls on the Green and the
Red Channels, and a new pull Boost on the Red Channel’s Gain control
(The Green/Brit Channel has Normal/Clean and Top Boost/Overdrive
modes, and the Red/American Channel has Tweed/Clean, Hi1/
Brit Gain, and Hi2/Boogie Gain modes). For the Brit-minded purist,
both reverb and loop circuitry can be hard-bypassed to retain maximum
attack and vintage-approved sensitivity.
The TA-30 sports the same style metal enclosure as the TA-15, though
it’s a few inches wider. Removing the four screws on each side of the
enclosure allows you full access to the power tubes and reverb tank.
Further disassembly is required to access the preamp tubes, however.
(Mesa’s Doug West adds: “We kept hearing from players and rental
companies that they needed a top-mount, Brit-style amp that provides
easy serviceability in stage environments. The combo versions of the
TA-30 incorporate a removable vented access panel held on by six Phillips-
head screws, that—unlike some other top-mount designs—allows
easy access to the tubes without the need to take the amp apart.”)
For my first test, I wanted to see how the reverb sounded with a
delay pedal, so I plugged in my Gretsch 6118-LTV and a Line 6 Echo
Park into the TA-30, ran the head into a
2x12 Transatlantic cabinet, and proceeded
to pull up a rockabilly tone by using the Hi2
setting on the Red channel with the Gain at
eight o’clock, Master at two o’clock, Treble
at noon, and the Bass at 11 o’clock. I set the
Reverb to nine o’clock and ran the Echo Park
through the amp’s effects loop. The result
was strikingly similar to Brian Setzer’s tone
on “Sleepwalk.” The reverb was smooth and
full sounding, and it didn’t interfere with
the clarity of the notes, even when turned
all the way up.
Next, I went for a Wes Montgomery-type
tone using a Gibson Howard Roberts Fusion
III guitar. Switching to the Red channel and
Tweed mode, I set the power to 40 watts (you
can select 15, 30, or 40 watts), turned the
Volume and Treble controls to 11 o’clock,
and boosted the Bass up to one o’clock. I also
kept the Cut/Master knob pushed in for Cut
mode (which attenuates high frequencies),
and dialed it to two o’clock. The tones had
a delicious jazzy sweetness and warmth, and
amp revealed even the slightest changes in
my attack and dynamics.
Among the tones that the TA-30 does best
is an AC/DC-style rhythm sound. Using my
PRS Custom 22 loaded with 57/08 pickups, I
set the amp to the Top Boost mode and engaged
the master function by pulling out the Cut/
Master knob. The setting that worked the best
for crunchy rock chords was the master at 10
o’clock, volume at noon, treble at 11 o’clock,
and the bass at noon. While the TA-30 introduces
a new variety of spongy British sounds
to the Mesa family, the amp stays true to its
high-gain ancestors in Hi1 and Hi2 modes. I
found that pushing the gain in the Hi1 setting
delivered articulated and pumpy overdrive
that was great for drop-tuned riffs. The Hi2
setting added a touch more gain and low end
that worked really well for sustained soloing
and burning leads.
Bottom line: If you’re looking for one amp
that can deliver a wide variety of tones and
is loud, responsive, and portable, the TA-30
is a must-hear for tone seekers.
