I own two 5125s and a 5127. All with the dynasonics. I just LOVE the tone of these guitars and why I own three. All have the extra tension bar on the Bigsby. 1 came with a roller bridge, the other two with the standard bridges. I, personally, think the one with the roller bridge sounds better, but it's a slight difference between the two that could equate to pickup magnet heights more than anything, although I try to match them closely. But, I did research here and it seems most think the roller bridge sacrifices tone. I haven't noticed it when comparing my guitars without a roller and the one with, but it seems many here feel this is true. I don't use the Bigsby a ton, and the roller bridge stays in tune better than the non-rollers. It's by a significant, noticeable amount. My roller bridge measures ~2 1/32" E to E ~2 7/8" stud to stud ~5/32" stud screw ends Just curious if others have made the switch. What they thought? Which bridge they bought that worked well with these guitars when you made the shift. Thanks for any help!
