The D'Addario O-Port is designed to fit most common soundholes. It offers a fuller, louder, and clearer sound with better projection for guitars, whether you're a beginner or own a custom - made one. This O - Port can also reduce feedback on acoustic - electric guitars. Made from a custom - blended polymer, it's easy to install and won't damage your guitar's finish. Ideal for all music genres, both in live performances and studio recordings. You can install it simply by loosening or removing the strings and fitting it into the soundhole. There are two sizes available: the large one fits 3.875' - 4' (9.843cm - 10.16cm) soundholes, and the small one fits 3.375' - 3.5' (8.573cm - 8.89cm) soundholes.
Using your D'Addario O - Port is a breeze. First, loosen or take off the strings of your guitar. Then, place the O - Port into the soundhole. If you have a large soundhole between 3.875' - 4' (9.843cm - 10.16cm), use the large O - Port. For a smaller soundhole of 3.375' - 3.5' (8.573cm - 8.89cm), go for the small one. When using it on an acoustic - electric guitar, you'll notice less feedback. As for maintenance, just keep it clean. You can use a soft cloth to wipe it gently. And remember, since it's made of a custom - blended polymer, don't expose it to extreme temperatures or harsh chemicals as it might damage the material and affect its performance.
