Recently installed a B-Blender on a B-50 Bigsby Squier Telecaster. I am using D'Addario 10's out of a 3-pak container. 2 of the 3 B strings have unwound at the ball after ab0ut a week of light playing. Is this a problem with B-benders as well? Is it unique to B-Blenders? Or did I buy a pack of dud strings? Am I going to need to solder the windings on the B strings?
