Hello everyone, this is my first thread so please let me know if I did something wrong. Recently I purchased a used Yamaha Pacifica 612v (2004 MiJ) with r1000v tremolo bridge. As I was trying to set it up I noticed something odd on the bridge. One of the studs holding the bridge is coming out from the body, causing on side of the bridge to be tilted a little. Also the same sides stud screw allen key hole is rounded off, so I cannot adjust or take it off. What would you recommend for me to do? I already tried to contact Yamaha about replacement screws, but didn't get a reply from them. I found some replacement screws from China, which are cheap and I doubt they will be any good. Should I just tap it in with a hammer? Please help me!
