Roland AP-7 Jet Phaser
Debut: 1975
Best known for creating the swirling, nasally fuzz sound on the Isley Brothers hit, “Who’s that Lady,” the Jet Phaser combined a multi-setting phase shifter with a fuzz circuit that was probably lifted from Roland’s Bee Baa pedal. The rarely-seen AP-7 packs a bunch of controls and specializes in psychedelic colors that no combination of fuzz and phaser can quite duplicate.
