The G string on my DeArmond Ashbory snapped, so I decided to replace them with Thunderguts. These work and sound great! A bit stiffer, not as sticky as the originals, they have more of a plastic and less rubbery feel. The sound is similar, I can't really tell the difference, however since I haven't A-B-tested them I am not sure. Fingers crossed that these will last longer, too.
