I recently converted my 5 string to a 6 string and I went with lighter gauge strings for the EADGC (100-80-60-40-30) but my Low B is a 130. Not a big deal, but it's a big string. I'd like to try a lighter gauge B string. Anyone know who makes the lightest gauge Low B nickel string? I'm thinking a 120 or even a 115 to try out.
