The One Control Beth Reverb is a reverb pedal developed in collaboration with guitarist Tomo Fujita, described by One Control as his signature pedal for maximum expression. It expands on the company's Prussian Blue Reverb and carries two distinct reverb types, Reverb A and Reverb B, that can be accessed seamlessly with a footswitch1.
One Control's product page listed the Beth Reverb as sold out as of 26 October 20261.
Two reverbs on one pedal
The Beth Reverb's core idea is two reverb types in one enclosure. An A/B switch lets you alternate between Reverb A and Reverb B on the fly, and a dedicated on/off switch engages or bypasses the effect1.
- Reverb A: One Control describes it as combining spacious sound diffusion with a dynamic range that enhances the guitar's natural qualities without overwhelming it, with the decay time subtly modulated for a spatial effect1.
- Reverb B: Inspired by classic plate reverb, One Control describes it as a more pronounced and enveloping effect in which the original guitar tone is subtly reinforced, providing added body and warmth1.
The pedal has built-in muting during reverb switching and effect engagement, which One Control says prevents noise or signal interference when you change reverbs mid-performance1.
Controls
| Control | What it does |
|---|---|
| Reverb A Tone | Controls the brightness or darkness of the reverb effect1 |
| Reverb B Level | Balances the reverb volume in the mix1 |
| Reverb B Intensity | Adjusts the reverb's strength, from a subtle background to a prominent spatial presence1 |
| Reverb B Decay | Sets the reverb tail's length for more control over sustain1 |
Note that the Tone control belongs to Reverb A only; Reverb B is shaped with its own Level, Intensity and Decay knobs1.

Questions
Who designed the One Control Beth Reverb?
The Beth Reverb is a signature pedal developed in collaboration with Tomo Fujita, the world-renowned guitarist and Berklee professor. One Control describes it as a result of that collaboration, built as a signature pedal for maximum expression, and it expands on the company's own Prussian Blue Reverb circuit.
What is the difference between Reverb A and Reverb B on the Beth Reverb?
Reverb A combines spacious sound diffusion with a dynamic range that One Control says enhances the guitar's natural qualities without overwhelming it, with decay time subtly modulated for a spatial effect. Reverb B is inspired by classic plate reverb and is a more pronounced, enveloping effect in which the original guitar tone is subtly reinforced with added body and warmth.
What power supply does the Beth Reverb need?
One Control specifies a standard 9V DC adapter with a center-minus plug. Current consumption is 60mA. The pedal's input impedance is 500K and its output impedance is 2K.
Does the Beth Reverb have a tone control for both reverbs?
No. The Tone knob, which controls the brightness or darkness of the reverb effect, belongs to Reverb A. Reverb B has its own set of controls: Level to balance the reverb volume in the mix, Intensity to adjust the reverb's strength, and Decay to set the length of the reverb tail.
Where can I find the Beth Reverb manual?
One Control hosts the Beth Reverb manual as a PDF on its own site, linked from the Beth Reverb product page. The manual file is the Beth Reverb v1.01 English edition.
How much does the One Control Beth Reverb weigh?
One Control lists the weight of the Beth Reverb at 390g. Its dimensions are 80W x 120D x 30H mm without protrusions, or 85W x 120D x 48H mm with protrusions.
