Detail 01
TUSQ XL vs plain TUSQ
XL is impregnated with PTFE, a dry lubricant. Strings slide instead of catching, which is what fixes bending-induced tuning drift.

Graph TechTUSQ XL 1/4" Epiphone Slotted Nut
Independent shopping perspective
The Korena take
TUSQ XL replacement nut pre-slotted to Epiphone dimensions. For fixing a worn or binding nut on an Epiphone-spec neck.
Strong match
Who this is for
- Curing tuning drift caused by strings sticking in the nut
- Replacing a chipped factory nut on an Epiphone
- Pairing with a fret dress and full setup
Consider the trade-offs
When to look elsewhere
- Gibson necks — the 1/4 inch thickness is different
- Anyone without gauged nut files to finish the slots
- Players who prefer the brighter attack of bone or brass
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
1/4 inch thickness
Notably thicker front-to-back than the Gibson-cut version. This is the dimension that decides whether it fits your slot at all.
Detail 03
1-3/4 inch length (1.735 actual)
Sized for a standard Epiphone nut slot. Ends usually need light sanding to sit flush with the fretboard edges.
Detail 04
1-3/8 inch E-to-E spacing
Narrower outer-string spread than the Gibson-cut nut. Affects how close the low E sits to the fretboard edge.
Detail 05
3/8 inch height
Left oversized on purpose. Sand the base down in small steps and check first-fret action as you go.
Final check
Know before you order
- 01Slot depths still need cutting with proper nut files
- 02Nothing else in the box — no glue, files, or shims
- 03Check your existing nut thickness; 1/4 inch will not fit a Gibson slot
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What does the XL actually do?
It is TUSQ with PTFE lubricant through the material. The slots stay slippery permanently, so no need to keep applying graphite or nut sauce.
02Will this stop my tuning problems?
It fixes drift caused by strings binding in the nut slots. It will not help if the cause is worn tuners, a bad string tree, or stretchy new strings.
03Can I use it on a Gibson?
Not directly. This is 1/4 inch thick versus the Gibson cut's 3/16 inch. Choose the Gibson-slotted version for those necks.
04Is this a beginner job?
Removal and gluing are straightforward. Cutting slot depth correctly is not — too deep means open-string buzz and a new nut.
