The Stereo Polyphase is a cool pedal. The feature set is pretty nice I really dig the slow envelope mode, which is something I’m missing with my current envelope filter.
The square wave mode is also a nice feature, and you can get some pretty cool sounds with that, especially in conjunction with an expression pedal. It’s a tweaker pedal for sure.
The expression mode is really cool. You can tweak it to be in the range of the stuff you’re playing and with distortion have the resonance be right in that range and you get these cool feedbacky notes. Add some vibrato and it’s quite wonderful. It’d be awesome if they made just an EHX “wah” that was just that mode of the Polyphase in a Wah enclosure.
Cons:
-it’s pretty subtle sounding, even for my tastes
-hard to find a perfect setting on
-never really find myself using it to write songs
-expression pedal jack placement, most expression pedals don’t use right angle jacks for some reason, so it’s in a bad spot.
Though I don’t really consider myself much of a modulation guy, so take my words with a grain of salt if you are. I could be perfectly happy if my board was just a pitch shifter, a ring mod, a tuner, some fuzzes, and a looper.
