Messed up locking studs
Hey guys! I want to ask something. Just restringed my RG 550, and decided to set it up again, cause i barely play this guitar now. The reason is that when i play it my Jackson which i mainly use on gigs seems to me like a plank with strings. Anyway this is not important. So adjusted the truss rod and the action on the lower frets is ok. Now the bottom stud moves and i lowered it as desired, but the top one (thick strings) i lowered a little and it stopped. Wont move anymore. I need to lower it a little more and everything will be great but doesn't move. Now when i put the proper allen wrench in both studs it just rotates like there is nothing no locking nothing just a hole. I presume that they are gone the guitar is made in 1987 lots of time has passed. I can take it to a luthier, the guys is one of if not the best in my country, but i now i just dont have the time to do it, so if someone of you can help with some advise i will be really tankful!
