ZOMA Stereo Reverb and Tremolo
Meet the ZOMA Stereo Reverb and Tremolo – Keeley's most high-fidelity pro Reverb and Tremolo ever!
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.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them.
Perhaps I just got a bum pair?

Quality and comfort
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Comfortable and fit well. I got these to replace a very old pair that finally wore out! Warmth is medium (I wear puffer booties for when it's really cold). Quality on these is great!

Can't go wrong with Acorn for as long as they last!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
Acorn is just a great company all around. I had bought my husband these slippers over 20 years ago. They are still in great shape although the sole has worn in some places. But nothing's coming apart! However, I decided to replace them for him. His foot is 10.5 and they are a little hard to get on right away-of course, after over 20 years of having "worn in" the original pair, anything would feel tight. So I'm not holding this against them. They will relax with use. The only difference is that the original sole was black and these are tan. I think I would prefer the black, but since it's only being worn in the house, no big deal.
My husband has really cold feet and these slippers never fail to warm his feet right up! He said they feel really soft to walk in and like the cushioning. They're not too heavy and fit him great! I have Acorn slippers myself that I've worn every single day in the house and outside to the mailbox too. They last.

Very warm and comfortable. A little difficult to put on with the collared top.
