Depends on the guitar/tuning. Mine are all different. My LP is currently in B Std. with 13-60 (wound G), My acoustic is 13-56 (Std), My custom MLF is 10-46 (D Std.), My DBDT ML is 9-46 (E Std./Drop D), my other ML is out of commission at the moment. Was in 9-42 but, I snapped the low E; I was way too used to 10-52 Std. and I bent the shit out of those strings. I'm trying to play with a lighter touch so, I've been going lighter with picks and strings and focusing more on my technique.
