Keeley Verb-O-Trem Reverb and Tremolo Pedal

Inject classic amplifier effects into any rig with the Verb-O-Trem. Choose between three distinctive tremolo voices to dial in your own personalized sound.

The Keeley VoT reverb and tremolo combo gives players a simple and beautiful sounding way to end their pedal boards. Reverb and Tremolo often sound best at the end of your guitar rig, after effects like compression, fuzz or overdrive. The Keeley VoT gives you famous Keeley spring and plate reverbs as well as modulated tube amp tremolos. This immaculate pairing provides you with everything you need for a small, compact pedal board.

Keeley Spring Reverb allows you to get that splashy spring sound that instantly fattens your guitar tone. If you want something super smooth, flip it over to switch in the Plate Reverb. Get that huge plate reverb sheen by simply flipping a switch!

You have three blooming tremolos in the Keeley VoT.
R+T - is an organic tube bias type tremolo. This means you hear the tube amp bias change enough to modulate the volume. A very personal and haunting tremolo.
Mack - This mode is a MagnaAmp style pitch vibrato. Done by carefully changing the phase to elicit a silky smooth pitch shift.
HAR - Harmonically Amplified Resonator. Harmonic Tremolo - two filters that vine around, back and forth, creating a notch filter that gives you that Tower of Flower sound.

VoT - Lotus:
Here's where the flowering magic occurs: you can set the VoT to be either Reverb OR Tremolo OR Both if you want. Let's say you just need some 'verb for the night, simply reduce the Depth control! Reverb Purity.

I have been on a sort of journey as far as tremolo and reverb are concerned. A Music Man amp from the 70’s was gifted to me. Amazing!!!! I know. It has a few pot issues but other than that it’s awesome. The best thing about the amp was the reverb and vibrato built into this Leo Fender masterpiece. I have been looking for this in a pedal. For I can’t play the Music Man out at gigs. Too old and I don’t want to deteriorate it by moving it around. The verb o trem has ended my long search. It sounds great! No noise. The different tremolo modes are all great. I flipped the dip switch under the hood to plate reverb. I prefer it on this model plus I have spring reverb in my current amp. Been using the 2 reverbs and tremolo together. Highly recommend this pedal if you are looking for what I was looking for.
