Classic fuzz with a searing upper octave- the ?-Octave is a high gain silicon fuzz circuit with a switchable octave up effect. Switch it in for classic octave up leads or break new ground and use it for heavy chording with lots of gnarly random overtones as the octave circuit tries to find the root note, double stop bends get that twisted multi octave sound with the high octave climbing while a subtle sub octave slowly drops in pitch. Switch out the octave for a more straightforward fuzz that sounds great with humbuckers or single coils and note how the LED changes from purple to blue to show the octave on/off status.
Plug in a bass and turn on the octave up for synth like fuzz textures that will put a smile on your face every time you turn it on. *Warning*- overuse of octave up effect guaranteed to annoy family, bandmates and audience alike, please use this pedal responsibly.
