FEEDBACK/SUSTAINER CONTROLS FDBK - The feedback switch is used to configure Dr. Distorto's unique harmonic sustainer circuit.
Off - This disables the feedback portion of the pedal, leaving Rise, Fall and Blend non-functional. This setting is great for using Dr. Distorto as a distortion box only.
Sustain - Provides a sustained tone that will be in unison with any single note played.
Octave - Provides a sustained tone that is one octave above any single note played.
Rise - Adjusts the amount of time it takes the feedbacker to begin sustaining a tone. Fall - Adjusts the amount time it takes the feedbacker to stop sustaining a tone. Blend - Adjusts the volume of the feedbacker's sustained tone.
DISTORTION CONTROLS Level - The Level knob controls the output level of the pedal. It does not affect the pedal's tone or FX section in any other way. Drive - The Drive knob dials in the amount of distortion created by the pedal. Use this with the tone knob to dial in the perfect overdriven tone. Tone - The Tone knob allows you to smoothly morph from a fuzz distortion tone to a classic drive tone using only one dial. Gate - The Gate switch is used to reduce signal noise, hum, and hiss when you are not playing.
Off - Disables the gate function completely.
Mild - A soft gate, when minimal noise attenuation is needed. The gate's threshold is linked to the Drive knob for best results at any setting.
Clamp - A hard, clamping gate with a quick response to cut out all noise between notes. The gate's threshold is linked to the Drive knob for best results at any setting.
