## Description

graphtech black tusq nut 6 string electric 43 x 6

Review: Because your old nut is a sharp-edged, plastic piece of... - Perfect fit*(see update below) for PRS Tremonti SE and a set of 10 - 46 strings. SE's come with 9 - 42s, and while they are fun to play, the increased sustain with the thicker gauge is evident from the first strum. A great upgrade to get rid of that sharp edged, cheap looking white plastic nut that has no reason being on such an otherwise outstanding guitar. The nut swap is an easy-enough project, and the perfect time to refinish your fret-board with some #0000 steel wool and 100% mineral oil (don't forget to tape off your PUP's - as these magnets are, well a magnet, for all those steel shavings). I recommend watching a vid on the nut replacement, carefully score the finish around the old nut, and the old one comes off easy enough with the tap of a mallet. Use a little wood glue, and a Capo to clamp it in place for 24 hours to dry, yes, I know you're going to want to string it and play after like 15 minutes, but it will likely fall out every time you replace the strings unless you actually form a chemical bond. Otherwise, the alignment is 100% flush with both wide-thin & wide-fat necks, and string slotting are both superior to the OEM nut. Never had an issue holding tuning with the stop-tail Tremonti previously (had to use pencil graphite on the nut as a lubricant), and it's rock solid (and additive-free) after the change as well. Intonation changed slightly with the 10 - 46s, requiring a slight adjustment at the bridge. This can be problematic on a stop-tail bridge -- with the PRS, tightening the hex screws actually lengthens the scale length which is counter-intuitive. The bridge will slide right out w/o string tension holding it down, take a look at it to see how this works. There are no individual adjustments, supposedly if you intonate the high-E at the 12th, followed by the low-E, the other strings intonation magically fall in place. Actually, it works pretty well for the middle strings, but can be difficult to get both E's near perfect at the same time w/o a high-quality solid scope. No truss rod adjustment was (or should be) necessary moving from 9s to 10s. *Update 8/27/16 I did get a professional set-up a few weeks after installing this nut. The intonation issue was pre-existing, and virtually the same problem translated with the TUSQ nut out-of-the-box. Intonation around the lower frets (closest to the nut had always been off - and improved as I went up the neck). This is a slotting issue and relevant to having a proper set-up, so I can no longer say it's a perfect fit. The 9s the guitar came with were replaced pretty quickly w/10's, so I cannot for certain say if this was a string gauge issue. Since I did not have the proper tools and gauges to do this myself, I had a skilled luthier go over the guitar, and it increased playability with numerous slight adjustments. At around $35 highly recommended. The intonation is very good and barring chords close to the nut requires less effort if your tolerances are tight (too far and you'll get fret buzz). Still a 5-star nut for price/performance just believe most people can benefit from having it properly slotted.
Review: Very consistent - Great nut! I love these, they sound really good and strings glide through smoothly. They are extremely easy to shape and cut very rapidly. Take your time installing because you can cut them down too quickly. They your in nicely and have a nice bright sound.

## Questions & Answers

**Q: which nut do i need to replace the black one on my epiphone less  paul ?**
A: You need to pay very close attention to the string spacing on your guitar. This nut is for a string spacing of 1-3/8". Epiphone Les pauls have a string spacing at the nut of 1 3/8". USA Gibson Les Pauls have a string spacing of 1-7/16". That 1/16" makes a difference.  You make sure you get the right one. The string spacing on this particular nut is 1-3/8" which will also fit an ESP LTD EC series guitar. Graph Tech does make an exact fit for a 1-7/16" Les Paul nut. These are good quality.

**Q: Will this fit Ibanez Gio guitar?  If not can a nut be recommended?**
A: It needs to match the neck radius and the string width. Measure those two things and if it matches this nut then it should fit. To measure the radius I just made a template from cardboard. Height wise this nut has plenty of stock to be fit to any neck. I think I ended up sanding about 1/8" off the bottom to fit it to my Yamaha se350 (strat style guitar).

**Q: Will this fit a Jackson js22 dinky ?**
A: Whatever nut you decide on, some adjustment will be needed.  If you don’t have the tools to do it, bring to a luthier.  If you do decide to do it, you will need a caliper and some files.   Good luck.

**Q: Is this for a right-handed guitar?**
A: Yes

### ⭐⭐⭐⭐⭐ One of the best and most affordable upgrades to most guitars.
*by K***N on November 3, 2025*

Graphtech Tusq XL and Tusq XL Black nuts are my go to nut anytime I am doing a nut replacement. I find that these nuts combined with good locking tuners and when applicable Tusq XL string trees, drastically improves tuning stability and reduces string binding. I highly recommend these nuts, just double, triple, and even quadruple check that you are ordering the correct one for your needs, it is easy to mistakenly order the wrong size or material, note that the Tusq is Ivory color and non lubricated (which could increase string binding compared with the self lubricating versions but still better than most other materials, I have mistakenly ordered this version a couple of times), Tusq XL is Ivory colored and self lubricating, Tusq XL Black is colored Black as the name indicates and is also self lubricating. The difference in the two versions of Tusq XL is purely aesthetic so just go with whichever color might match better with your guitar. I have also noticed improved tone, sustain, and less string breakage with all versions.
