Heads up Builders widely report inconsistent quality from PCB Guitar Mania boards, and whether a given board works is a gamble. Read recent forum reports before ordering.

Project Overview
This pedal takes inspiration from classic Phase 90 without being an exact copy. We took the iconic single-pot orange pedal and added a whole new level of control over the phaser effect.
We’ve included a potentiometer for Depth, allowing you to dial in the perfect amount of modulation intensity, and switches for Stages, Width, and Script, providing you with deeper mastery over your phaser tones.
