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.
Adds fuzz to your signal and then duplicates it two octaves down.
Control the mix of the dry signal and the effect.
Used by Jimmy Page for the solo in Led Zeppelin’s "Fool in the Rain."
Power: Dunlop ECB003 AC Adapter (not included) or Single 9 volt battery.
