MXR Phase 100 MXR107
The MXR Blue Box is the crazy effect heard on Jimmy Page’s “Fool in the Rain” solo. It 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.
Adds fuzz to your signal and then duplicates it 2 octaves down
