MusicRadar rating

4 of 5

Pros

Masses of potential. Highly interactive. Abundance of great sounds.

Cons

Cost is high when you add an expression pedal.

The bottom line

The asking price for the Stereo Polyphase may seem steep. But with 24-volt operation and extensive features, what a phaser this is.
