i am thinking of buying a 50's supro resoglass, and its a good price and i have owned 3 of them before so i know what to expect. unfortunately the seller just informed me (with rare honesty and ethics!) the neck has a very slight bow at the 7th fret. this guitar does not have a truss rod. it is simply a fat chunk of wood, like an old harmony, kay, valco, airline etc. so the problem is I cant reach my repair guy until monday at the soonest, and i need to hit this sucker before its gone. and no, it is NOT on ebay!! he says it plays ok enough, but the action is a little high, and stresses its a minor bow. he did not say which direction. does anyone know if this is a simple repair for a professional? and is this an EXPENSIVE job?! the chances of finding a replacement neck are slim to none. so please help!!
