The Keeley Vibe O Verb is a reverb pedal with a twist: instead of modulating your dry signal, it applies classic effects to the reverb only. Keeley describes the result as "Lost reverbs that never were," letting you "create new sounds and textures like never before"1.
What it does
The pedal runs in three modes, each putting a different classic effect on just the reverb tail. As Delicious Audio's Paolo De Gregorio put it when the pedal launched in June 2017, "This three mode reverb lets you hear what some of the most classic effects sound like on just the reverb," describing the atmospheres as "Vibey, have Vibratoneness, and are Phasery"1. In other words, vibe, vibrato and phaser character are applied to the wet signal alone, so your underlying tone stays untouched while the reverb itself takes on the movement.
The Verb O Trem family
The Vibe O Verb sits within a wider family of Keeley tremolo and reverb pedals. MusicRadar's Trevor Curwen, reviewing the related Eddie Heinzelman Signature Vibe o Verb Workstation in 2026, described Keeley as having "brought out a definitive tremolo and reverb pedal in two versions": a single footswitch model of the Verb O Trem and the fuller Workstation2.
Of that pedal's character, Curwen wrote: "The largely traditional/vintage sounds should appeal to those who play more rootsy music styles, but the functionality h..."2, positioning it as a fine utility addition to any player's signal chain.
The Vibe O Verb and the Verb O Trem-based Workstation pedals are related but distinct: the Vibe O Verb puts classic modulation effects on the reverb only, while the Verb O Trem family combines tremolo and reverb21.
