My Les Paul doesn't stay in tune.

I'm still going to say nut.

Outside of this, how far down is your bridge clamped to the surface of the top? What's the angle like there?

Have you ever tried throwing the strings over the tailpiece as opposed to through it?

Options - seriously - try the bridge height thing (a tech should know if it's too steep or too flat) and barring all these matters (nut included), try the strings over the tailpiece.

Nut. Easy fix with a nut file to widen. But, since it's been to a tech for a new nut and refret, he needs to take it back and have the guy check his work and get the nut filed for the string size. Adjust the neck if needed. Intonation on a LP will sometimes drive you crazy, but if not intonated, it will sound out all the time up the neck.

Another improvement, if the OP wants to spend a little more on it is a locking Tone Pro's tailpiece and a lock Tone Pro's bridge with new studs. If there is any slop on the bridge, this will kill the tuning and intonation.

I see this all the time with guys replacing tuners and bridges when almost always it is either poor string winding or the nut. Get in the habit of pressing hard on all strings over pickups, retune and press hard on all strings again. Each time retune it and repeat, each time strings will go out of tune less and after about 3 times it should stay in tune for whole gig. Big bends nut sauce will help any you may also need a good tech to do you nut. Also, bigger string gauge will usually require wider nut slots to prevent string sticking.

Grover tuners if you have the stock classic ivory ones..

My Custom NEVER goes out of tune. I string my strings properly, Grover machine heads , I tune to Eb, & have a bone nut. ZERO issues. Good luck!

As well as nut oil, check your bridge to see if the little grooves are too worn to keep the string from sliding from side to side. Also this time of year, the weather can play havok with instruments under AC, near windows, or anywhere else that has a changing of temp. Always play every strings with bends before you tune.

The G on my LP is the only unstable string. Everything else stays fairly in tune.
