Just wondering how hard it is to install a bigsby on a tele? I have a stock tele with a vintage style bridge on it and I've really been wanting to add a bigsby to it. My concern is neck angle-- I have no problem getting a vintage style bridge that has the slots in the back that allow the strings to go from the bigsby over the saddles, but I'd really rather not have to install a tune-o-matic style bridge assembly. Can a bigsby+vintage style bridge assembly work with just a possible shim for the neck? Or would I even need a shim to get the right break angle for that type of setup?
