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.
raucous fuzz pedal with double-octave-down capabilities, the MXR Octafuzz is a distinctive sound that thickens up licks and riffs for massive tone that is hard to miss. Down and dirty, the M-103 allows you to control the mix of the effect so you can try to tame this beast! MXR pedals have great tone, are built to last and represent excellent value for money. You can be sure that the box under your foot will deliver great quality tone gig after gig.
