Used MXR M103 Blue Box Sub Octave Fuzz Pedal With Box - 2

This is the crazy effect heard on Jimmy Page's Fool in the Rain solo. The Blue Box Octave Fuzz 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 fuzz tone is mixed with the two octaves down signal. Not for the timid-there is truly nothing like the Blue Box. This pedal is in excellent condition and comes with a box.
