Electro-Harmonix Founder and President, Mike Matthews and serial inventor Bob Myer go way back. Together, they designed the very first Big Muff and had a working relationship throughout EHX’s storied history. Always innovating, Bob was known to present Mike with updated designs to keep up with available technology of the times. As the process goes, designs get selected and others get put aside and forgotten about. The Big Muff Pi 2 Dual Op-Amp design is one that didn’t make the cut back in the late 70’s and was promptly stashed away in Bob’s files. While interviewing Bob in his old workshop, EHX disciples Josh Scott (of JHS Pedals) and Daniel Danger uncovered this novel circuit design as a hand drawn schematic amongst Bob’s old notes. Josh went to work decoding the original schematic and resurrected the circuit as the Big Muff Pi 2.
