I am considering getting a TonePros locking bridge for my new Yamaha SA2200. The main reason is that I want to be able to remove all the strings without having to intonate the guitar all over again because of the lose bridge. It is my first guitar with a T-O-M system so I hope to get help with some issues. I have not been able to find detailed info about the bridge and tailpiece on the SA2200 anywhere. It turns out that they are Gotoh and as I understand the bridge is Nashville-type. I am pretty sure that it is a Gotoh GE103B and I am guessing that the posts are screwed straight into the wood of the centerblock since there seem to be no bushings. I am thinking that I can install the TonePros bridge on the existing Gotoh posts and thumb wheels and lock it in place. The TonePros bridge that seems to fit is the T3BP. The holes for the posts seem to fit the M4-sized posts. My concern is if the distance between the posts will fit the TonePros T3BP. The distance between the holes for the posts on the Gotoh bridge is 74 mm. For the TonePros bridge I have found measurements ranging from 73.99 mm to 74.5 mm. Does anyone know for sure if it will fit? And if so, is it a good idea? And also; do you think that I will get the benefit of the improved sustain that TonePros claim to have with this simple arrangement? And finally (if you haven't fallen asleep yet) there's the question about radius: The Yamaha SA2200 has a fretboard radius of 13 3/4" (350 mm). I am pretty sure that the bridge has a radius of 12". Still the strings, of course, each have a perfect height from the fretboard. Does this make sense?
