Quick guide from the manual
The One Control Prussian Blue Reverb Revival 15th Anniversary is a limited edition reverb pedal designed to provide a natural, high-quality reverb tone suitable for electric guitar, bass, and acoustic instruments. It features a 24-bit digital chip with a custom BJF program, while maintaining an analog dry-through signal path.
Controls and Connections
- INPUT: Connect your guitar or bass cable here.
- OUTPUT: Connect this to your amplifier.
- LEVEL: Adjusts the output volume of the effect.
- DECAY: Controls the length of the reverb tail (from 2ms to 2s).
- TONE: Adjusts the high-frequency content of the reverb. Turning clockwise increases high frequencies; counter-clockwise decreases them. This does not affect the dry signal.
- KILL DRY (Internal): A switch located inside the pedal that mutes the dry signal. Useful for parallel effect loops.
- FOOT SWITCH: Toggles the effect on and off. Features true bypass when off.
- DC INPUT: Connect a standard 9V DC center-negative power adapter (One Control EPA-2000 recommended).
Power Supply and Battery
The pedal can be powered by a 9V DC adapter or a 006P 9V battery. To install a battery, remove the four screws on the back plate and open the cover. Note that the battery is not included.
Usage Tips
When you first power on the unit, wait a few seconds for the internal digital chip to stabilize. During this time, the pedal may be in bypass mode. Because the effect is sensitive, small noises from cables may be processed by the reverb; if you need complete silence, ensure the effect is bypassed.

Practical help
Common problems
Unstable sound immediately after power-up
Wait a few seconds after connecting power for the internal digital chip to stabilize.
Small amount of sound heard when muted
If using the Kill Dry function, bypass the effect completely for a full mute, as the effect may process small noises from cables.
Before use
