The Keeley Verb O Trem combines two timeless effects—lush reverb and vintage-inspired tremolo—into a single compact pedal, delivering everything from subtle ambience to rich, pulsing textures. Designed for players who want classic amp-style sounds without sacrificing pedalboard space, the Verb O Trem offers intuitive controls and studio-quality performance.

The reverb section provides warm, spacious ambience that enhances your tone without overpowering it, while the tremolo delivers smooth, musical modulation inspired by the classic tube amplifiers of the 1960s. Use each effect independently or combine them to create immersive surf, blues, indie, country, worship and ambient soundscapes.

With simple controls for both effects, the Verb O Trem makes it easy to dial in anything from gentle movement and room ambience to dramatic, cinematic washes. Its premium analogue dry path preserves the character of your guitar and amplifier, while true bypass ensures your signal remains pristine when the pedal is disengaged.

Built with Keeley's renowned attention to detail, the Verb O Trem is equally at home on stage, in the studio or as part of a compact grab-and-go rig.
