The Big Muff Multi is a versatile pedal based on the EHX Big Muff Pi. It features a smart Multi Muff PCB that can accommodate four mounted pots and a toggle switch. However, not all variants of the pedal use all four pots. You can refer to the parts lists to determine if your version has three or four pots.

The main deviation from the standard circuit is the addition of a clipping diode toggle switch, which enhances the pedal’s versatility. The Big Muff Multi offers different circuit specifications that cover various eras of muffage. While most of them are similar, if you’re looking for a classic Muff sound, you can opt for The Original or The Green Russian variants. For a heavier tone, the Stoner Spec is recommended, and if you prefer something more boutique, the Whoof variant is available.
