Bridge pins are small, cylindrical pins that maintain the strings in place on an acoustic guitar. They’re usually manufactured from plastic or bone, and they’re inserted into the bridge of the guitar.
To take away a bridge pin, you will have a pair of needle-nose pliers. Gently grip the pin with the pliers, after which twist it counterclockwise to loosen it. As soon as the pin is unfastened, you’ll be able to pull it out of the bridge by hand.
