From the vendor

Project overview

The boutique fuzz that covers that will make you feel you are dialing your classic fuzz on 15 rather than 10. This circuit combines the best of LPB1, Big muff, and Fuzz Face to create its unique “Imminent Amp Death” sound.

Introduction

If you are into pedal building and guitar effects in general for sure, you love to experiment with stacking fuzzes, overdrives, boosts, and drives to create your own trademark sound, don’t you?

Have you ever tried stacking Big Muff between a booster and a fuzz face? If you did you, found how insanely cool, loud, and saturated it could get, but it is an issue to dial-up and carry it around. Plus, not always all these pedals will get along together.

Pete Cornish addressed this issue, making a unique fuzz that delivers a thick creamy, saturated fuzz while keeping an original feel and taking distance from other boutique muffs such as the Black musket or Pharaoh deluxe.

For this model, we recommend you try different diodes for D1 and D2; leaving them empty can really turn this muff into a real doom machine! Another interesting idea would be to try some NPN germanium transistors for the Fuzz Face section, Q4 and Q5. For the Muff and boost section, I’d rather stick to stock ones as it won’t have such an impact on the overall tone.
