Graph TechPT-1200-00 4 String Bass TUSQ Nut Black
1/3
Independent shopping perspective
The Korena take
A pre-shaped TUSQ replacement nut for 4-string bass. For players swapping a worn, cracked or badly cut nut, or chasing more consistent open-string tone.
Strong match
Who this is for
- Replacing a chipped or badly slotted nut on a 4-string bass
- Techs who want a blank close to final dimensions
- Fixing open strings that ring or sustain unevenly
Consider the trade-offs
When to look elsewhere
- 5- and 6-string basses — this is a 4-string blank
- Anyone unwilling to file slots or glue a nut in place
- Guitars — the string spacing and width are bass-specific
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
1.224 inch E-to-E spacing
Sets how far apart the outer strings sit. Compare against your current nut before buying.
Detail 03
1.614 x 0.181 x 0.348 inch
Length, thickness and height. The slot in your neck must match the 0.181 inch thickness.
Detail 04
Pre-slotted blank
Slots start close but usually need filing to depth for your string gauges and action.
Detail 05
Black finish
Reads as a dark line at the headstock end rather than the white of bone or standard TUSQ.
Final check
Know before you order
- 01Measure your existing nut's length, thickness and height first — fit is not universal
- 02Nut files and glue are not included
- 03Slot depth almost always needs final filing; too deep means open-string buzz
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my bass?
Only if your nut slot matches 1.614 inch long by 0.181 inch thick, with 0.348 inch of height to work with. Measure before ordering.
02Is it pre-slotted or a blank?
It comes shaped with string spacing set at 1.224 inch E-to-E, but slots typically need filing to final depth for your gauges.
03Can I install it myself?
If you can remove the old nut cleanly and file slots to depth, yes. Cutting too deep is not reversible — otherwise see a tech.
04Does TUSQ sound different from bone?
It is more consistent piece to piece, since bone varies in density. Expect even sustain across all four open strings.
