Don't paint it yet! Check into fEARful cabs; they're a free-on-the net homebrew design, but you can find them ready-made, and maybe used (though I can't imagine selling one). I went to see Edwin's band Shakedown Street (in Denver, as it happens), and his fEARful 15/6/1 sounded absolutely magisterial. After the gig, he told me to pick it up; as a former roadie I know what it takes to hoist something like that, and lifted accordingly. Almost threw through the roof! I want say it was 32 lbs or some such (Edwin?).
