A few days ago while changing the strings on my RG520QS, the A string saddle got hosed. It appears that the string block was misaligned, and the long screw that secures it and the string in the saddle got a flat part just on the inside of the saddle, between it and the block, so now I cannot tighten it anymore, nor can I back it out. I checked Ibanezrules.com, and he doesn't have any in stock. Ordering one is going to take a long time. Hopefully someone has one. I'd prefer Cosmo Chrome, but at this point I'll take what I can get. PM me if you have anything.
