Does anyone else have a problem with the Ashbory's G string spontaneously popping (most often it seems, on the way to a gig)? I have never once had it happen while I was playing, and none of the other strings has ever broken. While it has broken most often near the head, because of how far the silicone strings stretch, I can't tell where exactly on the instrument the string broke. The nut doesn't appear to have a sharp edge, and the G string has snapped in various places, including down near the bridge. Is this just poor QC and a fact of life that goes along with using an Ashbory? Or could there be flaw I can't see in the nut that is responsible for at least some of the string failures? Any comments or suggestions would be appreciated. (I would especially appreciate hearing if anyone has succeeded in getting Fender/DeArmond to sell individual G strings.) Thanks.
