An octave and fuzz pedal, adding an extra note two octaves below the one you play. It’s monophonic but the glitching effect as it struggles to identify what note you’re playing is part of the fun of this pedal
This is the crazy effect heard on Jimmy Page's "Fool in the Rain" solo. The Blue Box takes your guitar signal and duplicates it two octaves down for a huge, subterranean tone. The Blend knob lets you control how much of the effected tone you mix in with your dry signal. Not for the timid—there is truly nothing like the Blue Box.
Power: Dunlop ECB003 AC Adapter or Single 9 volt battery
