i've posted earlier and was told to adjust my truss rod-- turn anti counter closewise.. because my strings were hitting my neck. now everytime i tune my strings to see if it worked or not, my bridge pins are popping up. i guess it didn't? i don't know, now i'm just confused.
push on your bridge pin while you tune up and they should stay in place. they should have a slight lock when you put them in without any tension, but when you start to increase the tension, it may want to pull out so just hold it down a bit. dont use too much force though. just enough to hold it in.
