Excessive string breakage...HELP!!!
I'm with Jeremy for sure. You want to check the string when it breaks. Does the string break right at the smashed point? Or does the string curve over the angled part and then break right at the point where it leaves the saddle? If all that is left when you pull out the extra piece of string is the flattened part, you are tightening the nut too hard. If you are pulling out a flattened piece of string with a plump section about 1/8" long on it, then it is definitely your saddle, and not your tightening. *Sometimes saddles can look smooth and still have burrs, or your picking style is to blame. The TRS saddles seem to have a wider, more relaxed curvature to them, which may lend itself to your speed picking style, whereas on the edge, the string rubs the sides of the saddle slot with each strum, not just the bottom. Look for burrs on the sides of the slot, too. But if your strings are breaking at the flattened point, it's probably the tightening. ALSO, *a lot of people check the saddle for burrs but don't check the angle at which the saddle "breaks" into the block hole. If there is a sharp corner there, it needs to be filed and smoothed. But edges are pretty good about that. I see that more on the TRS.
