Source Audio Vertigo Tremolo Pedal

Three Classic Amp Tremolos in One

Three classic tube trem effects

• Normal (Optical) — This mode reimagines an early iteration of the amp-based tremolo, which relied on a bulb and photoresistor. It's marked by a forward-sounding pulse, most famously found in the 1967 Vibrolux.
• Harmonic — This mode faithfully captures the modulated tremolo effects found in early-'60s American amps, specifically the 1962 Brownface Super. It results in a rich and complex effect that blends tremolo with subtle shades of phasing.
• Bias — This mode emulates the tremolo effects caused by modulating bias voltage across preamp tubes. The result is an extremely gratifying tube breakup that's rich in harmonics and presents in a distinctive pulse.

Dedicated controls, plus Shape

Along with dedicated controls for Speed, Depth, and Level, Vertigo gives you a waveform-morphing Shape control to coax new textures — square to sine waves, opto to sawtooth — from your favorite mainstay tremolo effects.

Configure settings via your phone or laptop
