The pedal with which it all began, for us in any case, the Big Muff is first and foremost the history of sixties rock music. The search for sound: Frank Zappa who hacks the circuits to the spacy sound of Pink Floyd's David Gilmour. Every musician knows the Big Muff, this mix of sustain and power. When things go wrong, when the rig doesn't work, it's time to take out the Big Muff, it's reliable, cheap and damn effective. Just ask Jack White.
