Feedback Buster™ Guitar Anti-feedback Device - New!
The Feedback Buster™ reduces feedback from acoustic/electric guitars. Simply insert the Feed-back Buster™ into the guitar's sound hole while using the pickup system. The principle is to control the resonance of the hollow body by simply closing the sound hole. Made from flexible neoprene, the Feedback Buster™ installs or removes in minutes and does not harm your guitar's finish. Fits most acoustic guitars and basses with standard round dreadnought size sound holes. (3 7/8" to 4" diameter )
