Keeley Zoma

Incredible stereo reverb and tremolo with the Zoma

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

Zoma Key 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.

The Zoma is more than just a pedal – it’s your signature.  Reverb and tremolo effects crown any player’s pedalboard. Trust Keeley reverbs for an inspiring “always-on” sound.

Three Reverb and Trem Modes:

We’ve combined the most popular ‘Verbs and Trems into three different pairs. There’s nothing quite like the syrupy smooth sound of our 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.

Stunning Design and Ease of Use

• Artful Electronic Circuitry: Housed in a proprietary angled aluminum enclosure for simplicity and durability.
• We stand behind EVERY Keeley pedal: Proudly Designed and Manufactured in the USA.
