New to the Heptode line of guitar effects: The Virtuoso Phase Shifter. 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) and 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.

Phasers are something that you want to sound warm, vintage and gooey. I am very intrigued by this unique boutique vintage offering from Heptode. Great sounding phasers are particularly rare.
