Re: Guitar Retainer/Tree
I don't think its presence or absence would really make much a difference to the guitar's setup, being that it's behind the locking nut. I suppose you could look for a generic RG one in the classifieds and if you like or see an improvement you could get a gold one from Rich, or just get one from Rich.
Right now I've got a 7VWH and a Jackson SL1 within a few feet of me, and both have locking nuts and tilt back headstocks. Only the Ibanez has the tree, and both play equally well and are equally well setup. Perhaps you need to venture off the coast and get someone to give that guitar a good setup for you?
