Univox Univibe

A 4 stage phase shifter without an op amp in sight. This pedal is legendary. It's often placed in its own category of just "vibe" as opposed to lumping it in with the '70s phase shifter crowd. Fulltone in particular uses the word "throb," and I think that's a good adjective for what might set the Univibe apart from other phase shifters.

It can also be categorized as a Leslie rotating speaker simulator. That was Fumio Mieda's original intent anyways. The VIBRATO and CHORUS labels are directly taken from organ terminology.
