The Disturbed pedal is capable of producing a variety of distorted fuzz tones, overtones and oscillations.
Disturbed has 5 controls
The Guitars Volume control affects the sound too. Roll off the volume whilst using a setting that's generating octaves will reduce the original note just leaving the octave or overtone.
The 1st 4 controls interact with each other i.e. the effect of 1 control depends on where the others are set, crazy stuff.
Disturbed is a low current consuming battery powered hand made stomp box with 1 output level control, an input connection on the right and output connection on the left, and a heavy duty bypass switch.
