The Virtuoso is a boutique recreation of the original Maestro* PS-1A Phase Shifter, as used in the 1970s by keyboardist John Paul Jones (Led Zeppelin) and guitarists Steve Howe (Yes), Alex Lifeson (Rush), Ernie Isley (Isley Brothers), among many others.

Footswitches below three colorful LEDs select SLOW, MEDIUM or FAST PHASE. The effect ramps up or down when changing from one speed to another and like the original, sounds superb with guitar or keyboards.

The Virtuoso’s modern features include a pedalboard-friendly footprint, battery or AC adapter operation, relay-based true bypass and a greatly improved signal-to-noise ratio.
