Hi guys. I notice that most PRS today comes with "hybrid" trem. It appears to have brass saddles and mounting screws. My question is, is there any tonal difference in addition to cosmetic? What material are the saddles on older trem made of? Steel or plated brass? If it's steel then there must be massive tonal difference old vs new PRS. Similar issue regarding the brass post on newer tuners, compared to chrome post on old tuners.
