A Must-Have for Playing Amplified Without Feedback
The Ernie Ball Soundhole Plug is designed to reduce feedback when playing an acoustic folk guitar equipped with a pickup and connected to an amplifier or PA system. By blocking the soundhole, it decreases air vibrations responsible for feedback, allowing you to increase volume more confidently and maintain better sound control, especially on stage or in small venues.
