MXR™ PHASE 90™ REPLICA COMPLETE KIT

A complete kit for an MXR™ Phase 90™ replica (script logo version), a very cool phase shifter with a beautiful, rich sound. Includes a matched set of JFETs.

About the effect

The Phase 90™ is the classic one-knob phaser heard on countless records since the 1970s. This replica follows the early script logo version, and our layout is very similar to the original MXR™ layout. We used 741 op-amps, which seem to be part of the "magic" in the sound of the old script logo units.

This kit is NOT for beginners or inexperienced builders.
