if i'm with the classic rock / NWOBHM band, i'll take my two Dean metalmans, and possibly my machine gun, if i'm at church, it'll be my us P, with poss my Jap p lyte (depending on the age of the strings on the us), and with the alt / industrial band, it'll be a dean metalman, ibanez 5, and possibly a p lyte back up.
i've rarely had breakage on stage, but if it's going to go, it's always at the wrong time! Since i'm a really heavy player, i need to have spares!
