Octorsion is a combination of two effects, octave up and distortion. Four knobs: volume, dist, octave and tone. The dist knob has a very big range and in the min position the sound is without distortion. Almost max gives a powerful yet “normal” dist. Max mode is a nasty hard dist that squeezes everything that goes out of the circuit. The octave knob is connected as a mix knob and you can get only dist or octave up, or a combination of both. It also means that you can get completely clean octave up if dist is in min and octave in max.
The volume knob is a traditional voltage divider max to zero volume out. The tone knob is a combined high- and low-pass filter so you can pick out the treble or bass of the tone.
