Upgrade your Floyd Rose guitar's performance with the Graph Tech Un-Lock nut.

Take your Floyd Rose-equipped electric guitar to the next level with the Graph Tech Black TUSQ XL Un-Lock Nut. Crafted for Floyd Rose bridges, this replacement nut integrates seamlessly without any guitar modifications needed. With advanced slot design and customizable string action, it ensures your guitar stays in tune and plays smoothly. The Un-Lock Nut's thoughtful design considers the unique string behavior on Floyd Rose tremolos. The reimagined slots hold each string securely, eliminating issues like tuning instability. No more frustration fiddling with tuning machines between songs. Just perfectly locked tuning. The nut's precise radius matching also improves accuracy. Now you can select the ideal radius for your guitar rather than settle for a mismatch.

Customize Your String Action

A major advantage of the Un-Lock Nut is the ability to customize each string's height. Dial in the perfect action for your playing style, from buttery smooth lead work to aggressive rhythm chugging. The nut accommodates a range of height adjustments, offering the versatility of a standard TUSQ XL nut. Find your sweet spot.

Enhance String Vibration and Reduce Friction

This nut's extended ramps distribute string tension more evenly across the nut. The result is better transfer of vibration along the strings for singing sustain and harmonics. Compounded with triple the self-lubrication of other nuts, you get silky smooth gliding during vibrato and bends. No more binding or catching. Just friction-free playability.
