The D’Addario Feedback Suppressor (formerly Screeching Halt) sound hole plug allows you to play your acoustic or electro acoustic guitar at far greater amp volume, without unwanted feedback or howling.
The tapered design allows for a great fit in most soundholes, while the inert material is safe for your instruments finish.
Simply place the Feedback Suppressor into the sound hole, and enjoy a feedback free performance.
