QUICK CHANGE - Grip-Lock tuners make changing strings a breeze. EASY AND FAST SETUP - The UMP (Universal Mount Plate) enable upgrades without drilling or screwing.
I like these a lot better than 2 other locking tuner brands I've owned. It can be really hard to hold tune because I have strong bending ability but these very well. Classy look, and open gears are realistic...no need to encase them. Win.
