When most players hear Source Audio effects, like their rich Flanger, funky-ass Stingray Multi-Filter, or out-of-this-world Multi-Wave Distortion, they’re instantly hooked. When some people see these effects, however, they’re intimidated by the deep feature sets, multifunction knobs, and general complexity. Well, now Source has come out with the One Series line of effects, which includes the Vertigo Tremolo reviewed here, a collection of simple and straightforward pedals.
I mean, the Vertigo is as it appears: a green box with four knobs and a couple of switches that does one cool thing when you stomp on it. If that’s all you need—a juicy, hypnotic, throbbing trem—the Vertigo will deliver in spades. Bam. Done.
The mad scientists at Source Audio did not stop there, of course. Before we go down their vertiginous wormhole, though, let’s talk about what the Vertigo offers on the surface: three types of trem, including Normal, which emulates the opto trem of blackface Fender amps; Harmonic, which goes after the vibrato circuit of the hallowed Fender Super; and Bias, which pays homage to tube bias-style modulation. You can modify any of these further with the Shape knob that can take you anywhere from square wave to sawtooth. I easily found a huge range of usable pulses with the three types and various Speed and Depth settings. I personally love it when a subtractive effect like a trem comes on with a slight boost, and the Level knob can give you that, although it is subtle.
So there you go. Simple, great-sounding mono trem at the touch of a button. You want more than that? Okay. The Vertigo’s stereo ins and outs mean that you can easily spread your pulsations out to two amps (it’s not nearly as dirty as it sounds). That’s when some of the more extreme waveforms like sawtooth really came to life for me.
Do you want to really go deep, though? You are in luck, my friend. Connect your Vertigo to Source’s ingenious Neuro Mobile App and several things will happen. First, you’ll gain access to a mind-boggling library of trem sounds that you can upload to your Vert. Not only that, but you also get control of a bunch of additional parameters for tweaking your trems, such as parametric EQ, wet/dry mix, and more.
They’re not done. Get down with the Neuro Hub (to be reviewed in an upcoming issue), which is kind of like a super-brain for all your Source effects, and you get full MIDI compatibility for this box, and the ability to save 128 presets, making the Vertigo one of the most versatile trems of all time.
Or it’s a guitar pedal that simply pumps out sweet-sounding trem when you step on it. Your call.
Source Audio is doing stuff that very few effects companies have ever tried to do. None of the bells and whistles would mean anything if the effects didn’t sound great, and they do— especially the Vertigo Tremolo. If you want vintage trem, wild trem, or never-heard-that-before trem, they’ve got you covered. A marvel of technology that sounds awesome to boot. Bravo!
Kudos Great tremolo effects. Excellent sound quality. Incredibly deep feature set.
