Not for PRS

The nut is brilliant. Improved tuning stability is noticeable, and tone and sustain is also improved. However these are too short for a PRS, there is a slight gap at the edge and can be felt when running your finger over it. Also the E to e spacing is too short. I have now ordered a Gibson nut, quoted as slightly longer and with the correct string spacing.

Fit perfectly for my guitar with a little bit of sanding.

After owning my ESP LTD MH-350NT for many many years, the stock nut was so worn. After a quick measure of the old nut, I noticed this seemed like a drop in replacement, width-wise. The nut slots are pre-cut nicely and work well with 11-56 without any more filing. The only thing I needed to do was sand the bottom of the nut to make sure the nut wasn't too tall when glued in.Obviously, your mileage may vary dependant on your guitar and DIY skill level.

Excellent quality Nut

I bought this for a 2006 PRS SE Singlecut to replace the plastic nut and although it works it's just a tad too narrow for the nut width on a PRS SE. Not by much but by enough (0.5mm to 1mm?) Graphtech states that it's 42.95mm wide but it measures 42.85 on my digital callipers.The nut itself is great quality but it's not an exact drop in for a PRS SE guitar. I guess it depends on just how exact you want to be.

Nice replacement for PRS

I had broken my golden rule of never buying a second hand guitar. I was having massive issues with fret buzz. Went through all of PRS’s setup procedures. In the end worked out it was the nut. The idiot that owned the guitar previously had filed the nut slots way too far past the point of no return. So bought this tusq nut. Had to do a minor bit of slot filing. But nothing beyond my capability as I build guitars in my spare time. Very easy to fit, and gives a glass like sound and clarity to your high end notes. Very pleased with this nut.

Fits Ibanez RGA perfect

Exactly same size as the crap plastic nuts that come on these, no shimming or anything required. Just gently sand the old glue off before fitting.Much better tone and does not slip out of tune while performing bends anymore.I am using standard 46-10 strings, if you were to use a heavy guage 52 etc the string grooves would need filing out.Other than that to take into account, fantastic.

Fitted my PRS SE perfectly

I needed to change the original nut in my PRS SE due to the B string slot being cut too low which created a buzzing. This one dropped straight in and the slot heights were perfect the width is spot on too.

It fitted with very little adjustment, l don't know why they are not fitted to all guitars
