A craftsman's upgrade for your Gibson acoustic.

The TUSQ Gibson acoustic guitar slotted nut is the perfect replacement or upgrade for your Gibson-style acoustic guitar. Made of premium TUSQ XL, a synthetic bone alternative, this nut enhances your guitar's tone and playability. The precisely machined nut slots are pre-cut to the correct string spacing so it drops right in—no adjustments needed.

Premium TUSQ XL Material for Rich Tone

TUSQ XL closely mimics the tonal properties of natural bone while improving on its durability. This high-tech but natural-sounding material produces richer harmonics, fuller sustain and a smooth feel under your fingers. Your notes will ring out with a warm, woody character that vintage Gibson acoustics are known for.

Precision-Crafted for Drop-in Install

This nut is carefully crafted to retrofit your specific Gibson acoustic guitar model. The string slots are pre-cut to the correct width and depth, so the nut installs easily without the need for filing or adjustments. For custom builds or vintage reissues, this OEM-quality nut helps ensure your guitar plays and sounds as intended.

Enhanced Playability and Tone

A properly cut nut is essential for maximizing an acoustic guitar's tone and playability. This high-quality TUSQ nut improves how cleanly your strings ring by providing firm, uniform support. Notes in the first position will sound clearer and fuller. And with string slots polished to a smooth finish, tuning and intonation are more stable. Your Gibson acoustic deserves a nut of this caliber.

Made for Gibson Guitars and Beyond

While designed as a drop-in replacement for most Gibson-style acoustics, this nut can also be customized to fit other guitars. Its quality construction and tone-enhancing TUSQ XL make it ideal for vintage reissues, custom builds and any acoustic where tone and precision matter most.
