i currently use 11s for standard, and i was planning on tunning to B standard (2 and a half steps down) and i was wondering what the string equivalent would be? 13s? 14s?
Personally I use 13s for C standard, although I checked intonation and made a couple of minor adjustments. Quite a few of the regulars here have mentioend that they happily ise 11s for C.
It's an opinion. It's subjective. And I'm right, anyway.
