Three reverb modes
You can choose tremolo-based, pitch-bending, or phaser-modulated movement within the reverb.

Independent shopping perspective
Keeley’s Vibe-O-Verb is a three-mode reverb pedal built around modulation within the reverb itself. Harmonic mode puts tremolo movement into the reflections, Vibrato mode bends their pitch from chorus-like motion toward more unusual textures, and Phaser mode adds shifting notches around the reverberant space. It is a focused way to make the reverb part of the sound design rather than leaving it as a static ambient layer.
