The Bearfoot FX Emerald Green Distortion Machine brings crunchy, germanium-driven tone in an easy-to-use stompbox with four controls for volume, distortion, voice, and treble. Designed to emulate the Vox AC series at its best, the Distortion Machine serves up bright, beautifully broken-up overdriven sound that can either complement your amp's existing overdrive sound or act as your dedicated crunchbox for bigger leads and crushing solos.
