The first sound effects built into amplifiers were tremolo and reverb. With the Zoma, Keeley’s legendary reverbs are paired with their sultry, vocal-like tremolos to give you an unreal sonic experience.

Three Reverb and Trem Modes:
Keeley has combined the most popular ‘Verbs and Trems into three different pairs. There’s nothing quite like the syrupy smooth sound of their Plate Reverb combined with Harmonic Tremolo:

SS – Spring Reverb and Sine Tremolo – Classic black panel amplifiers had spring reverb followed by a sine wave tremolo (at the power tubes)
PH – Plate Reverb and Harmonic Tremolo – Smooth reverb with swampy harmonic trem, what’s not to love?
PV – Plate Reverb and Pitch Vibrato – Vocal smooth vibrato with other-worldly reverb.

Reverb – Sounds and Controls

Spring Reverb: tube amp spring reverb – we simulate every detail of that classic vintage reverb sound.
Plate Reverb: bright, smooth reverb from a thin vibrating metal plate.
Reverb Decay: (Alt feature) Hold REVERB/ALT SWITCH down while adjusting Level knob.
Reverb Tone: (Alt feature) Hold REVERB/ALT SWITCH down while adjusting Rate knob.

Tremolo – Sounds and Controls

Sine Wave or Volume Tremolo: Sine wave tremolo simply adjusts the volume of the signal up and down.
Harmonic Tremolo: Just like tube-amp harmonic tremolo, your guitar signal is phase-split and filtered, almost like a phaser.
Pitch Vibrato: Bends the notes out of tune, you control how far and how fast.

Alt-Control-Tremolo Boost Volume: Hold REVERB/ALT footswitch down while adjusting Depth knob.
