Black TUSQ XL by Graph Tech Nut 6 Stringg Electric Nut 43 X 6 PT-6643-00

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.

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.

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.

I have a ibanez grgr131ex-bkf which has a plastic nut. I bought it and sand it from the bottom until it fits the correct height and glue it. Just that. It is a nice upgrade to my cheap guitar.

Fits great on a PRS SE Custom 24. My only issue is the G-E(hi) are filed down by the factory about a mm or so too deep. I know this might be my fault for not buying a blank nut, but I would like somewhere in the middle that starts the processes but allows me to fine tune the file down to the size I want. As it is, I don't want more then half of my string down in the nut, the G-E(hi) strings are completely covered. THAT SAID - The cut is good! So you don't get pinching and the tuning is great. But the default cut is wrong. It's too deep. Is it bad enough you shouldn't buy it? No, more so if you don't have files like I do, this would be a great replacement drop in without needing to file. Again, loved the item, just wish they had left a little more material on the higher strings for me to widdle down, E-A-D were perfect.

My 2018 made in Korea PRS se custom 22 with awesome sunburst flame top and f hole was having tuning issues on the g and b strings. I tried graphite powder and filing the nut slots for .010-046 strings. This helped but only for a short while, so i scored around the nut and it popped off easily enough. The new black graptech tusq xl was a perfect fit with no modifications needed. Just set it in with a few drops of white glue and restring and tune it up and the guitar was good to go. No more tuning issues. Thanx alot Graphtech for a great product.

This was a near-perfect replacement for the OEM nut on my PRS SE Zach Myers. The original nut was incredibly crude - very angular with edges sharp enough to make fretting painful. I of course sanded the edges but it still looked like hell. lt also had deep string channels that looked like a nice way to have string binding issues. When I saw this product I decided to give it a try. Installation was pretty easy - remove the strings and truss rod cover, score the top edge of the old nut where it met the head stock and then gently tap it with a small hammer/wood block. It popped right off. The TUSQ nut needed no sanding and I simply installed it with a couple small dots of white glue. Replace the strings and truss rod cover and you're done! I didn't have to make any adjustments to the nut slots for my 10-46 gage strings but I suspect you might have to if you use bigger diameters. If you're contemplating doing a replacement of this sort and have average or better tinkering skills, I recommend going for it. Life is too short to play with crude guitar nuts.

I'm not a guitar tech, but I'm pretty handy and tend to jump into things without reading the instructions. I first measured the string height on the low and high e with micro calipers. I loosened my strings until they could be moved off to the side, I removed the original nut from my pre ce by scribing around it on all sides with a razor then tapping it with a metal punch and a hammer, up from the fingerboard side. It came off clean. I then put the new nut in place and put the strings back on and tuned it up then measured the height. It was a little high, so I loosened the strings back down, and sanded the bottom of the nut held at an intentional angle to take a little more off one side than the other on some 400grit sandpaper on a table top. Repeated this a couple times until it all lined up. Left it unglued for a few days while I adjusted string height at the bridge and intonation until I was happy, then loosened it back up, add a drop of wood glue to the nut and spread it thin with my finger, then reassembled. Worked like a champ, plays great, and solved a problem I was having with the stock nut pinching the b string and causing a dull tone and poor sustain when unfretted. I didn't have to file the string grooves. I'm very happy.
