Looking to swap out the bridge on my 5220 to one without the retaining pin. Getting a bit of rattle noise when I play. Looking at TonePros or something similar for around $50. They have quite a few on Reverb priced right but not sure which one I need. I don't want to have to pull the bushings out if I can find one that screws right in. Am I looking for 6mm, 4mm posts? Doesn't have to be TonePros. Gotohs maybe? Any suggestions would be appreciated! PS Is all that rattle just from the saddles? I'm used to the Tele bridge so I was surprise by how much play is in the bridge and tail piece unstrung. Thanks!
