The stock 12" radius nickel/nickel steel bridge has the grooved saddles . . . . . . jus' wonderin' if a bridge replacement with roller saddles would make much difference (?) either theoretically or in reality/ practical experience. (They are a few bucks cheaper, so maybe these rollers are a cheaper material than the slider grooves ?) The afterlength after the saddles will be longer and less steep after the mods, fwiw. Thanks in advance for critique or comments.
