The Korena take

An unslotted TUSQ XL blank, 1/4" thick, for a tech or builder cutting a nut from scratch. Not a drop-in part.

Strong match

Who this is for

  • Luthiers cutting nut slots to a specific spacing and gauge
  • Instruments with a nut slot too thick for standard blanks
  • Repairs where no pre-slotted nut matches the neck

Consider the trade-offs

When to look elsewhere

  • Anyone without nut files and a way to measure slot depth
  • Players wanting a bolt-on replacement with slots already cut
  • Necks with a nut slot thinner than 1/4"

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 01

Slab blank

A flat rectangle with no slots, no radius, no shaping. Every dimension is cut by whoever installs it.

Detail 02

1/4" thick

Thicker than most factory nuts. Meant for slots that need it, or to be sanded down to your neck's actual width.

Detail 03

TUSQ XL

TUSQ with PTFE mixed through the material, so string slots stay slick without lubricant. Helps tuning stability on trem guitars.

Detail 04

Self-lubricating throughout

The lubricant is in the material, not a coating. Filing slots doesn't remove it, and it doesn't wear off.

Detail 05

Black

Colored through, so cutting and sanding won't reveal a different color underneath.

Final check

Know before you order

  1. 01No slots are cut. You need nut files in your string gauges
  2. 02Confirm the blank is larger than your nut slot in every dimension before cutting
  3. 03Radiusing the top to match your fretboard is part of the job

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01Is this pre-slotted?

No. It's a blank slab. You cut the slots, the radius, and the outer dimensions yourself, which is the point of a blank but means real work.

02What's the difference between TUSQ and TUSQ XL?

XL has PTFE lubricant mixed into the material itself. Strings slide more freely in the slots, which helps guitars with tremolos return to pitch.

03Will 1/4" fit my guitar?

Only if your nut slot is 1/4" or wider. Thinner slots mean sanding the blank down, which is doable but adds a step.

04Do I still need nut sauce or graphite?

No. The lubricant runs through the material, so freshly cut slots are already slick and stay that way as they wear.
