Guyker 43mm Stainless Steel Ball Adjustable Guitar Nut - Adjust Bridge Nut Split Regulation Replacement Parts Compatible with Gibson Les Paul LP Style Guitar

I build my custom guitars with a zero fret.....If you don't have a zero fret this will put your guitar way out of intonation. Before you take the old nut off, measure the nut to the first fret. This HAS to be the same when you put this new nut on, which it will not be. You'll have to remove the very end of the fretboard by about 3mm or so, so when the string goes over the balls, it will be the same distance from the first fret as your old nut. Don't try to fake it and you will have a great ball bearing nut. Odd, this unit comes with absolutely NO instructions if you're a newbie.

I’m writing a review to help some save their guitars from some weird suggestions about this nut.It was a slip replacement for my LP style, took minutes to install, looks and plays great, take the old one out, clean the site , a drop of glue for the base string the guitar and adjust the hight (very minor adjustments to the saddle might be needed) there is absolutely no need for cutting and filing…etc, please don’t cut anything, if your guitar’s nut is the same size you don’t need crazy modifications…. No it will not mess with your scale and intonation beyond the minor saddle adjustments.

Installation on an Epiphone Les Paul Special II took about 3 min. No sanding/filing of fretboard material needed whatsoever. Intonation and tuning at 1st fret is perfectly fine, confirmed with a tuner. This is because Guyker made this roller nut 180° backwards compared to the Fender LSR roller nut, string to nut contact from the 1st fret is exactly the same as the stock plastic nut this Guyker roller nut replaced. Super easy to install and the monumental difference was realized the first time tuning up. The stock tuners are no longer an issue since the strings are now on roller bearings, so I'll be keeping the stock tuners on this guitar, no reason whatsoever to change them out, so that saved about $60 for "real" tuners. When this nut was adjusted to desirable height, wow! This guitar plays like a very expensive guitar now. It could not be easier to do a superb action height setup with this nut. HIGHLY recommended! At this price, you can't go wrong, do it! You won't be disappointed.

The 43mm nut is for Fender scale guitars. Although advertised to fit Gibson necks, according to the Warmoth site, a nut measuring1-11/16" (43mm) wide is considered "Modern Medium" Fender width. "This is a standard nut width and closest to most modern Fender® necks."Prior to ordering, I measured the nut on my PRS Santana SE model. It's exactly 1-11/16 (43mm). Many PRS use F spacing. On my 2 American Strats and 1 Mexican Strat, the nut width measures 43mm or 1-11/16".Measure carefully! Otherwise, great product!

I wanted to like it but it just wouldn't stay in tune on my epiphone. When I did get to tune for a day the intonation wouldn't jive. It was sharp higher on the neck and not every string either, just most of them. Tried setting the height, the bridge, new strings, over and over. Nope. Here's the thing...The ball bearings are always in Flux if the string is vibrating.Think about it. I bought the one with the screw heads that the string sets on made of titanium to replace. That one works great. It's in the second pic of the guitar head. Made by the same company. Just stay away from the ball bearing type is my recommendation.

This item is way past due for guitar players that like to set their own string heights at the first fret. I love having one on my acoustic guitar now. But I have run into a couple issues that might be worth noting. One is that the neck side grooves may need a small amount of filing to get the string to ride on the balls. I found that if I used 14-52 strings it did ok. But when I went up to 14-56 the E, A, and D strings were not seating on the balls. I widened the slots to each of those strings a couple thousanths using jeweler's files. The other issue is that the strings come out of this nut flat. There is no arch and no way to raise the heights of the A through B strings to match your neck's radius. When I set the outside strings to the heights to .021", the D and G strings were sitting at .011" and were buzzing. What a bummer there. Using different sized balls would fix that or simply changing the design to include some kind of arch. The neck relief is now .013". It was .009". I had to add a little to it to quiten down the buzzing. Any more than that it became too hard to push the strings down.I know Fender is starting to use this type of nut on their electric guitars. Maybe they will come out wiht a properly designed adjustable nut for acoustic guitars.

Does what it's supposed to do well. I had to do a little cutting on the fingerboard to match the factor intonation. No big deal.

This nut is the best nut I’ve ever installed on a guitar ( so far ) I’ve had it installed for just about a week as a replacement for another type of roller nut that I installed previously. This nut holds intonation and tune after bending the strings really well it was easy to install on my Les Paul custom.. actually a slip in replacement.. I’m ordering one for my SG today
