About This Listing

A genuine vintage Electro-Harmonix Big Muff Op-Amp dating from late 1970's and believed to be from the early production period of the Op-Amp Big Muff Series. 

Can you name a 90's band that didn't use one of these? If so, let us know! 
Modded with a 9v output, but apart from that, all original and sounding killer!
