MXR™ PHASE 90™ REPLICA RTS PCB

The ready-to-solder PCB for our MXR™ Phase 90™ (script logo version) replica, a classic one-knob phase shifter.

About the effect

The script-logo Phase 90™ is the version many players chase for its smooth, vocal swirl. We based this project, the P90, on the original script-logo unit, and the layout is very similar to the original MXR™ layout. We chose it because the 741 op-amp ICs seem to be part of the "magic" sound of the old script-logo pedals. Jumpers are built into the board, so you can go straight to populating parts. If you would rather not source parts yourself, a complete P90 kit with this PCB is also available.
