The Feedback Buster is a simple yet essential tool for acoustic-electric players who want to take control of their live sound. Designed to fit most standard-sized soundholes, including those on Martin guitars, this insert dramatically reduces unwanted feedback when using a pickup system on stage.

Made from durable, flexible rubber, the Feedback Buster installs in seconds and stays securely in place without interfering with playing or damaging a guitar's finish. It is ideal for players strumming at high volume or performing in front of monitors, with a 102mm diameter tailored to fit snugly in most dreadnought and OM-style guitars.
