Roland - AP-7 Jet Phaser

Vintage 1975 Made in Japan - 4 Stage Phaser with Resonance Control and Slow / Fast Switch. The speed switch ramps the speed difference just like a leslie motor. There are 6 Modes of Phase available; the first four are Jet Phase modes and combine a fuzz circuit with the phasing. The 4 selections are hardwired bandpass filters, creating a preset EQ / voice. The last 2 phasing modes are clean (no fuzz) and are again different only in how they are EQd. The resonance control can create very vocal ‘yoy yoy’ sounds when maxed out. Runs exclusively on 2 x 9V batteries.
