Bringing back the look and feel of the coveted Phase 90 with the original script logo, the MXR Phase 90 Script Reissue demonstrates vintage style with modern sensibilities. The sound is as psychedelic as ever, continuing to provide the same phase shifted tone that made the Phase 90 a favorite of Eddie Van Halen's. The only real way to tell the Script Reissue apart from its predecessor is the LED status light.
