ELECTRO-HARMONIX RAM'S HEAD BIG MUFF Pi. This is a reissue by the original Electro-Harmonix of the 1973 Ram's Head Big Muff, which is currently traded at a very high price, in a compact nano-sized enclosure. Based on the V2 version, known for its purple paint, it features excellent note separation and intensely long sustain. It also incorporates modern specifications such as true bypass and 9V external power supply compatibility. Among the Big Muffs with their distinctive characteristics, I think this one is easy to use. It's also easy to use in a band setting. I highly recommend this to those who are buying a Big Muff for the first time. It was a pedal I really liked, but I'm selling it because I'm switching to a multi-effects unit. Thank you for looking.
