The optimally ramped and angled string slot design evenly distributes tension, enabling triple the lubrication!
The Un-Lock Nut® was created to solve common problems with traditional locking nuts, including difficulty bending strings in lower registers (like bending from G to A on the high E string), complex string replacements, and restricted access to machine heads for tuning.
The locking nut introduced in 1977 greatly enhanced guitars but also created challenges, such as limited access to machine heads for tuning and the hassle of adjusting fine tuners on the bridge. When a string broke, it required tedious adjustments with an Allen key. The introduction of locking tuners has transformed the experience. Enhance your guitar's tuning performance with the innovative Unlock Nut, designed for perfect compatibility with locking machine heads. Installation is straightforward.
We have four sizes to fit your guitar!
