Feedback Buster

Minimize stage and studio feedback and keep your performance clean and confident with the McPherson Feedback Buster. This smart and simple sound-hole plug does what it says: busts feedback.

Product Highlights

• Designed to fit a range of acoustic and acoustic guitars.

• Inserts easily into the sound-hole to reduce the “howl” and unwanted resonance when playing amplified. (Similar tools known in the industry: sound-hole covers, plug-in dampers.)

• Multiple size/variant options available; pick the size that suits your instrument’s body and sound-hole dimensions. 

• Lightweight, unobtrusive—when inserted properly it still allows you to play naturally while preventing excess resonance from building up under amplification.
