Keeley Zoma Stereo Reverb & Tremolo Guitar Effects Pedal

Reverb and tremolo effects crown any player’s pedalboard. The Zoma is more than just a pedal – it’s your signature and Keeley’s most high-fidelity pro Reverb & Tremolo ever. Trust Keeley reverbs for an inspiring “always-on” sound and vocal-like tremolos to give you an unreal sonic experience.

Main Features

• Simple Control Layout: Three large knobs give you maximum control over Reverb Level and Rate and Depth for Tremolo.
• Easy Access Alt-Controls: Reverb Decay, Reverb Tone, Tremolo Volume.
• Instant Effect Order Switching: Choose which signal path is right for you. Put your tremolos after the reverb for a vintage correct, black-panel tone. Experience a dirty, swampy tone with harmonic tremolo on top of reverb.
• True Bypass or Buffered Trails: You chose what sounds and works best in your rig.

Three Reverb and Trem Modes
Keeley have 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 - Keeley 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.
