Opto Tremolo
Based on the tremolo circuitry of the 1965 Fender® Deluxe Reverb® amplier, which
features a pulsing light source directed at a photo resistor.
Knob 1: Tremolo Speed.
Knob 2: Tremolo Depth.
Knob 3: Shape, from classic smooth tremolo to dramatic sci-fi throb.

input slows it down.
Knob 5: Mix. Tremolo usually sounds best from 90-100% wet.
Bias Tremolo
This Model emulates a classic Vox® tremolo circuit design. Bias tremolo produces a deep,
3-dimensional tremolo with a wide stereo spread.
Knob 1: Tremolo Speed.
Knob 2: Tremolo Depth.
Knob 3: Shape. The minimuim setting is a sign wave and max is a square wave.
Knob 4: Volme Sensitivity. Louder input signals speed up the tremolo and lower
volume inputs slow it down.
Knob 5: Mix. As with Opto, BiasTremolo usually sounds best from 90-100% wet.
