I've been using a crazy 8 for a year or so, it covers bigger gigs than i thought it would, people cant believe how much sound comes out of that thing, it's a great little cab. I drive it with a MESA D800, switched to 2 ohms to reduce power output, but the amp is still way more powerful than the cab should handle, but I regularly use it in restaurants and small pubs, I'm not saying its for heavy rock, but I have used it with a 17 piece big band, no DI and it did it....wouldn't like to push it any further, takes low B no problem. GLWS, great little cab
