In my quest of looking for a PRS I've come across a Epi with a Bigsby. Go figure!!! I have a few guitars w/Floyd Rose tremelos and love them mainly because onec they are locked in, they are locked in. This one has a Bisgby and I know nothing about them, necer played one. How are they as far as staying in tune? Won't be using this guitar (Riviera) for any aggressive (dive bombing) playing and probably won't use the system much at all. All inputs welcome, and thanks in advance. Dale
