The Triangle Big Muff Pi is a reissue of the very first Big Muff from 1969, the pedal that ushered in a legendary era. With its original circuit, it offers the same creamy sustain, rich harmonics, and distinctive mid-scoop EQ. The simple Volume, Tone, and Sustain controls make setup intuitive and musical. From subtle crunch to massive fuzz: this pedal delivers pure vintage authenticity. The Triangle Big Muff Pi is not just an effect, but a piece of rock history.
