There's nothing quite like the ’70s Electro-Harmonix Polyphase. With six stages of LDR-modulated analog magic that rival the sound of the most sought-after phase effects ever made, it has all the aspects that make for a great vintage effect. Not many were made and it’s difficult to replicate because it uses light-dependent resistors, which are long out of production.

The Polyphase takes your classic phasing sounds to a new dimension by activating its envelope mode. With controls for sensitivity, modulation, and modulation rate, you can dial in anything from a funky envelope filter sounds to some amazing Leslie rotating speaker tones. If you want the sound of that awesome intro to ‘No Quarter,’ this will get you there.
