This MXR Phase 90 has found its way into a wide array of rock recordings, adding a shimmery velocity to lead passages or a more dramatic swoosh to muted strumming. Not just for guitars, its a great effect with bass, keyboards and even vocals. Vary the speed from a subtle, long cycle to a fast, watery warble—and myriad vintage vibrations in between. Classic phasing with variable speed control, on/off switch. Uses nine-volt battery or optional ECB03 power supply. Theres no better unit for that classic phase shifter sound. Provides the classic four stage phasing sound with continuous variable speed control. Phase 90 fixed regeneration level adds intensity and is particularly effective for keyboards. Features: Foot accessible speed control knob LED on/off indicator Powered by AC Adapter and/or 9 volt battery
