Up for sale, a Source Audio Vertigo Tremolo pedal in like-new condition and in perfect working order, complete with the box and power supply. Part of Source Audio’s One Series, this Massachusetts-designed pedal offers three distinct tremolo effects, toggled through the central three-way switch.
- Normal tremolo is a recreation of the “opto trem”-style amplitude modulation found in vintage Black Panel Fender amps
-Harmonic tremolo is designed after the Fender Super’s “Vibrato” effect from the Brown Panel years
-Bias tremolo is slightly overdriven and sweet, designed to recreate the swampy “bias wiggle” of early tube bias modulation
The standard Depth, Speed, and Level controls are present; with further sculpting made possible via the Shape control, allowing the user to morph the overall LFO wave shape from square to sine/opto to sawtooth.
This unit is practically perfect, with the original box, 9V power supply, and 1/4”-to-3mm adapter cable.`
