Mike Matthews, founder and president of Electro-Harmonix, and prolific inventor Bob Myer have known each other for a long time. Together, they designed the very first Big Muff and have collaborated closely throughout the rich history of EHX. Always at the forefront of innovation, Bob used to propose updated designs to Mike to incorporate the latest technologies. Throughout the process, some projects are selected, while others are set aside and forgotten. The dual op-amp Big Muff Pi 2 project is one of those that was not chosen in the late 70s and was promptly tucked away in Bob's archives. During an interview with Bob in his old workshop, Josh Scott (of JHS Pedals) and Daniel Danger, two EHX disciples, discovered this original, hand-drawn circuit schematic among Bob's old notes. Josh set to work decrypting the original schematic and resurrected the circuit under the name Big Muff Pi 2.
