The elusive vintage "script" Phase 90 is a highly coveted addition to any pedal collector's repertoire. The original version, available from the company's inception to the late '70s, defined the classic phase shifter sound and was featured on everything from hard rock to jazz-fusion to funk hits. The MXR Custom Shop Script Phase 90 faithfully reproduces the headroom, clarity, warmth and smooth phasing, and reduced midrange swell of the original. It comes in the original smooth orange paint job and script logo with an LED and AC power jack, direct from the MXR Custom Shop.
