Welcome, you are looking at a great piece. This is the Electro Harmonix Bad Stone Phase Shifter.
The Bad Stone Phase Shifter pedal from EHX is a faithful recreation of the original circuit design and 3-knob control layout, but features up-to-date enhancements for the modern player.
It provides six stages of phase shifting plus a manual mode that lets the player freeze the phase. In addition to the pedalboard-friendly die-cast case, EHX updated this pedal with true bypass switching, an LED indicator, and an AC jack.
Here's your chance to own the legendary analog Bad Stone phase tone in a compact rock-solid package.
