Hey, does anyone out there know offhand if there's a rack case on the market that you can lock? I have my amp in a regular old SKB rack right now, and I just busted the vagrant, crackhead bass player in the band we share our space with using my amp without asking. Luckily, he didn't hurt it. But I don't want to haul my rack home every night, and until I can get those guys kicked out, I wish I could lock my rack case. Anybody know?
