Graph Tech Guitar Labs has expanded its innovative Un-Lock Nut line with two new models designed specifically for seven-string electric guitars. According to a report from mia.org.uk, these new components replace traditional metal locking nuts with a pre-slotted, triple-lubricated Black TUSQ XL nut. This design eliminates the clamps, hex keys, added weight and everyday hassles associated with a conventional locking nut. Designed for guitars equipped with double-locking tremolo systems, the seven-string Un-Lock Nut gives players excellent tuning stability while keeping the machine heads fully accessible.
Dave Dunwoodie, founder of Graph Tech Guitar Labs, stated that seven-string players often use different tunings and string gauges, so being able to tune at the machine heads and change strings quickly is a real advantage if they are using a tremolo stabilizer. The weight reduction is substantial: a traditional metal locking nut weighs roughly the same as four AAA batteries, while the Un-Lock Nut weighs about the same as one AAA battery. Made from Graph Tech’s triple-lubricated Black TUSQ XL, the Un-Lock Nut features advanced slot geometry that helps the strings move smoothly through the nut. Its extended ramps distribute string stress more evenly, while the accurately matched radius and individually adjustable string heights allow for a precise setup. Players also benefit from smoother, easier string bending in the lower fret positions. Both models are pre-slotted, accommodate most common string gauges and install without permanent modification to the guitar. As with any replacement nut, minor fitting and height adjustment may be required for the individual instrument. The new Graph Tech seven-string Un-Lock Nuts are available now for $24.95 USD each through Graph Tech and authorized Graph Tech dealers.
