Changing guitar nut to a teflon / graphite nut = good.

I put locking tuners on my old LP Studio Lite about a year ago and it helped with tuning. I decided to try a teflon / graphite nut for the heck of it.

Got the TREM-NUT slotted jumbo from someone on ebay for $7.

Getting the old nut out was as easy as the instructions said. Fitting the new one took a bit of time to sand it down. I left it higher than my previous nut and it really affected the action in a bad way, so I decided to shape it closer to my original (bone?) nut.

After 20 minutes of sanding, I got it to where I wanted it. I used some old strings to file the low E slot to fit the .52s I use.

I still didn't glue it in yet, because I may lower it, but I really like it. It has helped my tuning very much. My strings don't waver around tuning-wise. They pretty much get to tune and hold. The lockers helped with that and now this new nut really helps tuning.

PS - You can do as I did and leave it unglued. The strings hold it in very nicely. Once you decide that you like the height, then glue it.

If I did it over again, the one thing I'd do different is to make a jig so I can grind the new nut down square. I had to square it up as the 2nd to the last step in the sanding process.

I highly recommend trying this if you don't have one on your guitar.

Here's the kind of nut I got:

has anyone replaced their nut and had good results? I have to think that the stock nut I had sucked at this point, considereing how much better the tuning is now...

I've been waiting to replace the one on this jazz bass till I wasn't sick and busy. I think you've inspired me. Anyways, more than anything, time will tell with the nut.

My guitar has a roller bearing nut on it, and locking tuners. The fucker never goes out of tune.

Only cowboys stay in tune.

Thanks for the info. I just bought a new nut for my fretless bass. It's black and dull. The shop called it carbon fiber.

While am working on it, I am going to clear epoxy my rosewood fretboard like some of the other fretless basses and try to get a better sound.
