the word you're looking for is gauge. string gauge refers to its thickness.
they had a write-up in guitar world a few months back about him and they said he uses 11s. the brand it listed was DR if you were wondering about that, too.
But how are u tuned dudes ?
Coz id u're in DGCFAD, it can't be 0.09 I guess, that's why Alexi uses 0.11 ..
Yeah D'addario r my favorits ones, but I gonna test some DR ...
How do u do to change your gauge everytime guys, don't u have any Floyd tremolo system ?
Well with the floyd rose bridge, if you change the guage you probbably need to add another spring if you are usaully playing in E. Also you would need to adjust your intonation so that it sounds right as well.
Hey fatmrcrab, mixing string sizes ona FR guitar will fuck it up bad, you won't be able to intoneate it for shit, at least that what happened with my buddies RG-7.
