Strange title I know but let me explain. Recently picked up a Gibson Les Paul custom. The guitar came with 9's (I Think). Now personally I prefer 10's on my Gibson's, after re stringing with 10-46 Gibson bright wires, the guitar fights with me sometimes when I try and tune it up. At other times the issue is not present the guitar plays normally. Issue in question is mostly on the B and G strings, although the other strings have acted up in the past. What happens is when I pluck them, they immediately go sharp if I keep plucking them eventually they go from sharp to flat and then finally up to pitch. The guitar will then stay in tune only for a few minutes before going sour again. Things I have tried are Lubing the nut with graphite flossing the nut with thread and playing with no lube adjusted the height of the tail piece ( it was cranked all the way down against the body causing the strings to bind up heavily on bridge) Tightening the tuning knobs and and making sure the actually tuning machines themselves were properly tightened. Apologies for the long post, any help/suggestions would be greatly appreciated.
