The Ernie Ball Acoustic Sound Hole Cover stops loud squeaks and buzzing when you play your acoustic guitar. It fits sound holes up to 3-3/8". The cover is made of soft rubber, so it won't scratch your guitar. This piece blocks out feedback from loud speakers and helps keep dirt out of your instrument. You can install it without any tools—just push it into the sound hole and you're set. The cover works for both regular acoustic and acoustic-electric guitars. Now you can play at higher volume or on stage without that annoying hum messing with your sound.

Ernie Ball Rubber Design Stops Feedback on Stage

Anyone who plays live or wants a cleaner sound will find this cover useful. If you use an acoustic-electric guitar, feedback can make it hard to hear your music. The rubber cover fits snugly and blocks extra noise, so you hear your guitar, not a loud screech. Studio players and gigging musicians can use the cover to play louder or record with less background hum. Playing is easier when you don't worry about feedback or dirt inside your guitar.
