I'm sure you've heard of the stringsavers graphite saddles, I just got them and they are amazing. I have never broken a string on my guitar with these things on. They just simply go dead and then I need to change them. I play a Gibson Les Paul, and with my original saddles, I was breaking strings almost weekly. So if you haven't checked out the graphite saddles, do it.

p.s. If you're worried about them altering your sound, I have not noticed any kind of change in my sound.
