Virtuoso Phase Shifter
The Virtuoso Phase Shifter 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),
Alex Lifeson (Rush), Ernie Isley (Isley Brothers), among many others.
"The sound quality is so good that this could even be a studio device, made by a French company called Heptode"
L.A. first-call session guitarist
Member of Supertramp
"I have become a super fan of the Heptode phaser. I have even been using it during mixing and tracking of the new Aaron Neville record and couple of other really cool records! It's simple, well made, sounds great and is killer! I have a couple of other phase options, including Mutron and other classics, but the Heptode fully gets used over all of them these days. Awesome box!"

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.
