There are ways to go to a karaoke box or practice studio, but if you do this every day, it's not financially or time-wise. If you are having such a problem, you may be wondering if there is a way to reduce the sound somehow. Attach it to the sound hole as an acoustic guitar silencer for people who want to practice playing the guitar but don't want to disturb others with noise. A snug-fitting sound hole cover allows for night practice and reduces sound leakage. Useful for reducing guitar sounds such as electric-acoustic guitars, classical guitars, folk guitars, and ukuleles. ✅ [Hole Cover] When playing an electric-acoustic guitar (electric-acoustic) connected to an amplifier (guitar speaker), it prevents excessive feedback and allows the sound to be picked up (device that converts string vibrations into electrical signals). You can pick it up. For example, if the echoes from a performance are picked up again by the pickup, it can cause howling. These problems can be reduced by installing a sound hole cover. By attaching it to the sound hole of an electric acoustic guitar, it prevents excessive feedback and howling, allowing for even more dynamic performances. In addition, it is recommended not only to reduce the sound of the guitar, but also to prevent dust from entering the hall, insects from entering when performing outdoors, and for storage. ✅ [Easy to install] Made of soft rubber that is easy to use. Removal is easy. It is a sealed type that fits snugly into the sound hole, and is designed to fit into the sound hole of a typical guitar.
