Heptode Virtuoso Phase Shifter


Sold out.

Heptode Virtuoso The Heptode Virtuoso is a boutique recreation of the original Maestro® PS-1A Phase Shifter, as used in the 1970's by keyboardist John Paul Jones (Led Zeppelin) and guitarists Steve Howe (Yes) and Ernie Isley (Isley Brothers), among many others. Footswitches below three colorful LED's 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.

Simply listen to No Quarter (Led Zeppelin), Starship Trooper (Yes) or Who's That Lady (Isley Brothers) to experience the classic sound produced by the original PS-1A.
