Electro Harmonix Nano Triangle Big Muff Pi Fuzz Distortion Sustainer

Referred to as the "Triangle" Muff because of its signature volume, sustain, and tone knob layout, the original circuit was the very first Muff EHX made back in 1969, kicking off a line of fuzz pedals that would quickly become ubiquitous with the brand and a favorite among guitarists across a wide range of genres.
