Take control of your live sound with the Feedback Buster, a simple yet essential tool for acoustic-electric players. Designed to fit most standard-sized soundholes, including those on Martin guitars, this insert dramatically reduces unwanted feedback when using your pickup system on stage. Whether you're strumming at high volume or playing in front of monitors, the Feedback Buster helps ensure a cleaner, more controlled tone.
Made from durable, flexible rubber, the Feedback Buster installs in seconds and stays securely in place. It doesn't interfere with your playing or damage your guitar's finish, making it a reliable and reusable addition to any performance setup. With a 102mm diameter, it’s tailored to fit snugly in most dreadnought and OM-style guitars.
