I have two Cort guitars with the same type of Floyd Rose bridge. One is about 5 years older than another. Each of them has the same problem. The saddles are worn due to friction with the strings. It makes them serrated like a saw. Then it breaks the string frequently and throws the remaining strings out of tune.
I go to a luthier and he strips smooth again, but it never lasts long and the problem returns. I use tape between the string and the saddle to improve the durability.
My question is, there's a way to fix it without throwing them away and buying some new ones ?
