My local pawn shop has an 18" Black Widow cab for sale for $150. Worth it? They don't have any heads in for me to try it out on, but insist it works. $150 wouldn't really set me back too bad. I have a Black Widow 1516 (15 and 2 8s) and I think it's one of the best sounding cabs I've ever played out of. Anyway, does anybody have experience with the 18s?
