Re: Licensed floyd rose problem in RG550EX
Without seeing it for myself I won't be able to 100% identify the problem. I will agree with both Razzle & j.arledge that those are potential problem areas. Here are the things you should check.
The bridge may not be sitting fully in the neutral position. Cleaning the knife edges & studs and slight adjustments to the springs if needed will solve this. Also make sure the knife edges and studs aren't worn down. Light ware can be filed back straight if needed, if not replacement may be in order.
The sttrings may be slipping a little bit. Make sure eveything is locked down good at the locking nut and the string clamps on the saddle. Check for ware on these components also, if they are worn the strings won't be properly clamped down and will slip. If the nut is worn you'll probably have to replace it. If it's just worn clams you can replace those without replacing the whole nut. If the clamp on the saddles are worn replace them. Same thing as the nut, you can replace the clamps without having to replace the whole saddle unless the whole area is worn then the saddle may need replacing.
The strings may be catching on the saddles. Give the saddles a cleaning and check for any ware or knicks that may catch the strings. Minor knicks you may be able to file out, major ones you'll probably have to replace the saddle.
The hole the studs sit in may be ovaled a little bit due to ware and the studs are moving in it. If this is the case you'll probably need to plug the holes and redrill them.
*Quick note, anywhere I said you can file things back even this is only for very minor ware in which you just need to take out a small knick or ding that might be catching something. Don't do any major grinding on anything as that will screw up alignments then you'll may have to replace the entire bridge.
