Up for sale, a circa 1971 Big Muff Pi "Triangle Muff" in exceptional, 100% original condition and in perfect working order. The Triangle Muff is the first Big Muff offered by Electro Harmonix, and this is an exceedingly clean and 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 completely original and untouched.

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. All original transistors are intact, and at least one of these can be identified as a Fairchild Semiconductor 2N5133 NPN transistor (EHX was known to mix and match transistors on these circuits). This particular Muff is as thick, smooth, and articulate as they come, with scooped mids, ample bass, and detailed top end.

Cosmetically, this is an extremely clean example, with all of the original black silkscreen text intact and near mint textured sides and back, complete with the original rubber skid pad. The CTS pots date to 1966, consistent with all early Triangle Muffs, as EHX has purchased a significant stock of CTS pots from '66 despite Big Muff production commencing circa 1969-70. The original "pinch" style black Bakelite radio knobs are intact too.
