The MXR Phase 90 established the standard for phaser effects with its full and robust tone. Our in-house model, acquired in 1974, was carefully analyzed and replicated as the '74 Vintage Phase 90. The hand-wired board includes chosen resistors and hand-matched FETs to replicate the original's smooth and warm modulation. The '74 Vintage Phase 90 is encased in the iconic orange box and features the distinctive Script logo.
