So I have an issue with my Roto 77s in that the location of the taper of my E string (tuned D) is right on the tuning peg. More concerning is that the thread wrap on the string is sitting on top of the saddle when intonated, and I'm afraid it's going to fray. My thought has been to get some form of spacer between the ball end of the string and the bridge, but I'm having trouble finding a product which would be appropriate. I'm thinking a small brass cylinder to go over the string before it gets threaded into the bridge to shift the string downwards. I'm also not sure if that would be stable enough to keep the tension, and therefore tuning, consistent. Any ideas? Has anyone had similar problems, and how did you fix it?
