Graph Tech Trem Nut PT 1200

The nut is great as any other Graph Tech product: good material, enhances the tone and stabilizes the tuning, but it will require some extremely accurate work to fit a P bass.
The length and the string spacing are correct, but it's very much higher and deeper than a normal P bass nut, so it will need a lot of sanding.
However, the major letdown is that it's flat-bottomed, unlike a standard Fender nut, and that complicates the installation a lot.
So my advice is: buy it if you're going to install it behind the fretboard, skip it if it's for a Fender-type bass 'cause installing it will be too much of a hassle and if you're not VERY careful you'll ruin the nut and need to buy another one.

I really love the Thomann short scale bass, but the white plastic nut it comes with is really nasty and cheap. This nut is the perfect width for it.

I had to increase the width of nut slot with careful filing, but this nut is so much better and the bass seems to have much more sustain (I don't think it is just my imagination).

The nut iutself is quite deep, so whichever bass you need it for, it will require a substantial sanding down, but better there being too much which you can work with rather than too less.

The material feels like it is going to last, and from the sanding process to bring the heigth down, it comes across as a quite dense material.

So far, no problems, so I can highly recommend it.

As my first bass turned 33 years old, it deserved some refurbishing. Last not least, the nut was about to turn into dust. Actually, when I unglued it, it broke into 3 pieces...
Anyway, I took all the measurements, filed the new nut according to the neck radius and the desired height and glued it in place. When I restringed the bass, I immediately realized that the D string was lying way below the other three. After a couple of plucks, the impression was confirmed and the D string is unplayable (it keeps banging against the first fret when playing the empty string).
That's a pity because it sounds very good, way better than before (OK, the old cracked nut is not a proper reference here...) adding a lot of sustain.
I haven't sent it back because I modified it (N.B. I didn't touch the slots!), but eventually it turned into a waste of money.

Yes, the title might be read in two different ways but all in all, this graphite nut is fantastic. It really keeps the strings from detuning during songs and it has a nice feel to it.

I paired this with my Gretch Junior Jet 2 bass and it's a massive improvement upon the stock nut. One bad part about this bass is that it tends to detune pretty badly mid song, especially when using bends, because of its 30.5" scale. This nut paired with a Hi-Mass bridge helped with the overall detuning issues. I hope changing the tuners with some locking tuners will further improve on the issue.

Great nut!
