Hi,
my rg550 neck wont concave as I would like it to. The bolt is all loose but the strings dont pull enough to make the neck concave. It is just flat.
Is there something I can do to make the neck behave(not taking account filing the neck concave, luthiers neck heat-treatment or neck shimming)?
Also, i wonder if putting some 060-013 strings on the guitar would hurt the Edge knife edges?

(I feel pretty stupid with this question)
