This is the Vertigo Tremolo, another member of the Source Audio One Series of effects pedals. This is our first dedicated tremolo pedal and we are chomping at the bit to get this beauty out into the world. The control panel is simple (Depth, Speed, LFO Wave Shape, and Output), but the range of sounds that can be conjured with its four knob's is outstanding. The Vertigo has three types of tremolo: standard amplitude modulation, Harmonic Tremolo, which bounces between a high and low frequency bump for an effect that falls somewhere between a tremolo and a phaser, and finally Bias Tremolo, which gives you a dirtier, swampy effect. Things really get interesting with the Shape knob, this magic controller allows you to morph the tremolo LFO from a Fender Opto Trem, Sine Wave, Square Wave, and Reverse Saw Tooth.
Of course, like all the One Series pedals, the Vertigo comes with the free Neuro Effects Editor Software that allows users to access a extended menu of additional parameters. You'll want to jump in there and really fine tune the sound to perfectly fit your taste. Save your presets and upload them anytime, anywhere with the Neuro App for iOS and Android. The Vertigo's Effects Editor has a nice collection of additional controls including advanced equalization, modulating filter and delay effects (a.k.a "flanger") whose modulation speed can be synced to the tremolo rate.
