Reverb Tanks
Spring reverb tanks are used to create a unique reverberation effect in guitar amps and organs. The reverberation effect is created when an audio signal created by a transducer is sent through one or more springs, the movement of the springs is then converted back into an audio signal by another transducer at the other end, creating the unique sound. Not sure which tank you're looking for or what a 4AB3C1B is? Check out our spring reverb calculator to help you determine what these tank designations mean!

Mount these rubber grommets to the base of reverb tanks to help alleviate feedback and other vibration issues. The thick rubber ring helps with isolating the tank from the surface that it is mounted to or resting upon. These rubber grommets fit typical reverb tanks.
- Mounting Hole Diameter = 3/8"
