Yes, I've done the Low A thing too, and experienced the same. That ended the experiment for me. I would go to a larger gauge B. Something like .132 or .135. It may or may not work, depending on the string type and gauge you are using, but it is worth a try if you really want to use the low A. Gol to
www.jsutstrings.com and go to the single strings section. Good luck.
