AP-2 Phase II
The Roland AP-2 Phase II is a vintage analog phaser pedal produced in Japan between 1975 and 1978. Launched before Roland transitioned its effects line to the Boss brand, it is part of a rare series that includes the AS-1 Sustainer and AF-60 Bee Gee. This professional-grade pedal features a six-stage FET-based circuit that delivers lush, organic modulation ranging from slow, subtle sweeps to intense, spacey textures inspired by the Leslie rotating speaker. The interface is straightforward, featuring dedicated knobs for Rate and Resonance to manipulate the speed and shape of the phase shift. A notable technical feature is its 18V operation, powered by two 9V batteries, which provides significant headroom and clarity similar to the legendary Jet Phaser. Its circuit later served as the foundation for the original Boss PH-1. Highly sought after by collectors and musicians like Dimebag Darrell, the AP-2 remains celebrated for its warm, vintage character and robust build.
