MusicNomad’s patent pending GRIP Puller’s innovative design allows you to easily pull bridge pins. Simply slide under the pin to GRIP and pull straight up. Alternately, use a rocking motion to roll back and lift the pin. It’s that easy. The ergonomic, rubber lined comfort grip design has no moving parts and is a one-handed operation. Metal free construction with a rubber exterior makes it safe on delicate wood and all bridge pin types used on acoustic guitars.
