Custom Muff

Costalab creates boutique effects with classic inspiration and custom refinements. The Custom Muff puts their spin on the legendary fuzz circuit.

The Custom Muff is based on the Big Muff circuit with customized voicing and enhancements. The refined circuit delivers the massive sustain and singing fuzz of the original with improved tonal options.

With the classic three-knob layout and enhanced functionality, the Custom Muff provides wall-of-sound fuzz with boutique refinement and quality construction.
