Hello. I've been reading this forum a lot, so I finally joined, as I have a question about a new SG Standard 61 w/Maestro vibrola that I just purchased. I watched this video that details a few simple mods to increase the guitar's tuning stability: The two big suggestions are (1) inserting new Faber bridge posts to increase the stability of the overall bridge unit, and (2) replacing the stock ABR-1 bridge with a TonePros bridge with nylon saddles to reduce the friction with the strings on the saddles. In another video though, the same tech then says the TonePros bridge with nylon saddles did not work as well as expected (he gave it a B) and suggested instead that a bridge with roller saddles would be more effective at maintaining tuning stability. However, I have thus far been unable to find a suitable bridge with roller saddles. Does anyone here know if there is a drop-in replacement bridge for the ABR-1 with roller saddles? Thanks!
