MXR CSP026 ’74 Vintage Phase 90 Pedal


The ’74 Vintage Phase 90 is a faithful reissue of the original, featuring hand-matched FETs and a hand-wired circuit board.

This pedal can only be powered by one 9-volt battery (not included).


The MXR Phase 90 set the benchmark for phasers, with its thick and rich tone. Our in-house work horse, purchased in 1974, was meticulously spec'd and recreated as the ’74 Vintage Phase 90. The hand-wired board features select resistors paired with handmatched FETs to achieve the same smooth and warm modulation as the original. The ’74 Vintage Phase 90 comes housed in the classic orange finished box and is adorned with the unmistakable Script logo.
