Keeley announced the Zoma, a stereo reverb and tremolo pedal, on October 25, 2024. Guitar World reported three days later that it was available for $2291; Gearnews said at the time of its announcement that the pedal would soon be available for order at an MSRP of $2292.
The pedal has three large knobs for reverb level, tremolo rate and depth, with additional controls for reverb decay time, reverb tone and tremolo volume reached through an Alt button2. Guitar World describes the three knobs as Rate, Depth and Level, with secondary functions for Reverb Decay, Reverb Tone and Tremolo Volume, and says the alt functions are accessed by holding down the reverb footswitch1. A retro LED indicates tremolo speed2.
Three mode combinations are selected with a small DIP switch2. Guitar Pedal X describes the selection as a three-way toggle and notes that the tremolo and reverb modes are chosen together3.
| Mode | Reverb | Tremolo or vibrato |
|---|---|---|
| SS | Spring | Sine tremolo |
| PH | Plate | Harmonic tremolo |
| PV | Plate | Pitch vibrato |
The effects order can be flipped, so tremolo runs before or after the reverb2. Guitar World says holding both footswitches at once flips the order1. The pedal runs in true bypass or silent buffered bypass2, and top-mounted jacks provide stereo ins and outs plus a standard 9VDC jack1. It comes in Silver and Custom Shop Sand finishes1; Guitar Pedal X calls the Sand a more limited Custom Shop colourway3.
Guitar World reports Robert Keeley calling the Zoma "one of our crowning achievements" and Keeley's "most high-fidelity pedal to date"1. Guitar Pedal X calls it a follow-up to the California Girls, I Get Around and Halo Core pedals, and describes it as competition for the Strymon Flint and Fender Tre-Verb3. It also questions the plate reverb appearing in two of the three modes3.
"Don't be fooled by its simplicity. It's a wonderful-sounding machine," Keeley says.
Guitar Pedal X reports limited distribution through the Keeley webstore at $2293.
