Early 70’s Electro Harmonix Big Muff Pi “Triangle” Fuzz Guitar Pedal. Pedal is the “Triangle” version, the Holy Grail of Big Muff pedals! CTS pots date to 34th week of 1972 (1377234 with 137 being the manufacturer code, 72 being the year, and 34 being the 34th week of the year). Transistors are Fairchild Semiconductor FS37000. All components appear original (except perhaps one faceplate screw). Classic Big Muff sound, with long sustain and sweet fuzz, a sound that is not obtainable with modern transistors. Condition is very good for a 70’s pedal with minimal wear on the faceplate of the pedal, and also minimal wear on the bottom rubber skid plate. These pedal are very rare, and do not come up for sale often. Priced at $900 plus $25 shipping through Direct Sale (outside of eBay). PayPal accepted.
