The Keeley Zoma Stereo Reverb and Tremolo pedal combines two of history's most iconic amp-style effects into one ultra-high-fidelity, true-stereo stompbox. Designed and manufactured in the USA, the Zoma pairs Keeley's legendary digital reverb algorithms with three lush, vocal-like modulation modes, allowing you to instantly inject rich texturing and massive spatial depth into your rig while maintaining a 100% analog dry signal path.

The pedal features three expertly curated modes that pair distinct reverbs and modulations:

• SS (Spring and Sine): Delivers the classic character of vintage black-panel amplifiers, blending a splashy surf-style spring reverb with a smooth, pulsing sine wave volume tremolo.
• PH (Plate and Harmonic): Pairs a lush, studio-quality plate reverb with a chewy, phase-split harmonic tremolo for a warm, swampy, and psychedelic vibe.
• PV (Plate and Pitch Vibrato): Combines that same premium plate reverb with a true pitch-shifting vibrato circuit, capable of moving from a subtle, vintage sway to full-on lofi textures.

Despite its powerful stereo processing, the Zoma keeps things incredibly simple on the surface with a streamlined three-knob layout for Reverb Level, Tremolo Rate, and Tremolo Depth. However, it also boasts intuitive secondary features like adjustable Reverb Decay, Reverb Tone, and a Tremolo Volume boost. You can also instantly switch the effect order to run tremolo before reverb or vice versa, and choose between true bypass or buffered trails depending on your pedalboard's needs.
