Keeley ZOMA Stereo Reverb and Tremolo

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.
