We’ve all been excited to use our acoustic-electric guitar’s amplification system, only to be met with torrential outpourings of feedback and hum. Ernie Ball offers a convenient, simple solution with this Acoustic Soundhole Cover, an accessory that requires no tools for installation and slots neatly into most acoustic guitar soundholes. Once applied, a contoured seal stops amplified sound from entering the soundhole, thus eliminating feedback. These feedback-fighting properties not only guard the sound quality of your performances but also render your acoustic-electric more compatible with high-output gear — think overdrive pedals and electric guitar amps. Sweetwater guitarists also find this cover a convenient choice for outdoor gigs because it stops dirt and debris from reaching the inside of your guitar. And because the Acoustic Soundhole Cover’s rubber construction is naturally soft and non-abrasive, you’ll never have to fear a damaged soundhole or rosette. Stop feedback in its tracks with this handy Ernie Ball accessory!
