Hey,, I just picked up a Carvin LB76F and I'm looking to upgrade the strings (particularly the B). Mwah, warmth, growl are all good catch phrases, definately going with nickel roundwounds. I don't want to go any bigger than .135 for the B, and I could really use some help for getting more tension and tone out of it. Please recommend your findings (brands,sets, sizes, taper/exposed/wrapped core), these things are $35 + ! Not to mention there's 30 different companies at JustStrings.com, it could take me YEARS and big $$ to figure it out!
