The Stomp Under Foot Tri-Muff is based on a great version of a 1972 Big Muff Pi™ that, in my database, is known as Version 6.
The 1972 V6 has a full and strong low-end that produces huge, gritty, wooly chords and sweet, creamy lead tones.
The 1972 pedals are known for having a lot of gain which produces amazing harmonics that jump off the fret-board.
All Stomp Under Foot pedals are made by hand and use only quality, through-hole components.
