I am wondering if you guys could tell where to get single strings (of any brand) in bulk. the reason why I'm considering this is because I was playing my bass today, and really felt the tension was comfortable on my D and G strings, but the A and E (especially E) are a little floppy to my tastes. Thus I want 45,65,90,110s (up from a standard 45-105 set), but realized that this gauge set is hard if not impossible to find. Thanks. P.S. - if you could suggest string brands that would be more tense as a 45-105 set I would also be grateful. I play nickel roundwounds at this point.
