From the vendor

A vintage model recreation of the EHX Bad Stone Phaser. The project includes true bypass switching, the auto/manual switch and of course the phase/vibrato switch of the old unit. We have added a clean boost on the output along with 2 individual internal trimmers so the volume of each mode (Phaser/Vibrato) can be tailored to preference.
