Up for sale, a 1972 Big Muff Pi "Triangle Muff" in excellent condition and in perfect working order. The Triangle Muff is the first Big Muff offered by Electro Harmonix, and this is an early example, with the singing sustain and rich, saturated fuzz that has made this pedal a mainstay in studios and on the road for decades. Differentiated from the first edition of the V1 Triangle Muff by the On/Off switch and "Tone" text on the enclosure, this V1 second edition Muff circuit is loaded with the original quartet of Fairchild FS3699 silicon transistors.

The list of artists who gravitated to this particular Muff circuit early on in production is impressive, with Jimi Hendrix, Carlos Santana, John Lennon, Steve Howe of Yes, King Crimson and more gravitating to the pedal's unique and thick tone. Infamous for the constant component substitutions this circuit received while in production, there are 17 known minor variants of the Triangle Muff, and they all have a slightly unique tonal character while retaining the same general sonic footprint. This particular Muff is as thick, smooth, and articulate as they come, with scooped mids, ample bass, and detailed top end.

All original Fairchild FS3699 transistors are intact, along with the CTS pots which have source date codes from the 1st week of '72. The circuit is virtually untouched, and other stock components include the Japanese-made 1/4" jacks and the battery clip.

The enclosure top and silkscreen graphics show light wear, with only faint wear on the textured sides and back, complete with the original rubber skid pad. The original knobs are intact too.
