1978 Electro-Harmonix Little Big Muff Pi

Model Description:

Fuzz is dead; long live fuzz! One of the great and unmistakable sounds of the 1970s was that of the Electro‑Harmonix Little Big Muff Pi and its loftier sibling, the bigger Big Muff Pi. Mike Matthews and his band of quirky effect innovators from Rochester, New York City spawned a legendary effect pedal filled with fabulous fuzz‑fuelled excess in 1969. Jimi Hendrix, Carlos Santana and Ernie Isley became associated with these iconic boxes early on, fuelling further fuzzy fandom. While the more flexible Big Muff enables guitarists to dial in bucket loads of ϋber distortion and vary the tone, the Little Big Muff took a simpler approach to maximising massive sonic pandemonium.

Pedal Description:

This shiny little American stomp box is in excellent all‑original condition and works perfectly. The pot dates to early 1978, so it isn’t any older than that. Electro‑Harmonix added the convenience of a battery compartment to the base of their pedals in the late 1970s, not long before the company got into trouble and finally went bust in the early 1980s. The gargantuan level of extreme noise produced by this vintage Electro‑Harmonix Little Big Muff Pi is far from subtle and deftly evokes the spirit of the time – it sustains ‘forever’. No other pedal past or present comes close to emulating the Big Muff Pi’s signature harmonic craziness. Just stamp on the switch, defy convention and be transported effortlessly to analogue fuzz town. Love the fuzz. Wonderfully cool. Love Vintage Fuzz! NB. Pi = 3.1415926535… to infinity, and beyond.
