Peavey 1810 cabinet in super condition with casters (removable) added. This is a heavy beast, but sounds great and in great shape. I bought it from the original owner, who had it sitting at his church since he bought it, and used it on Sundays.
If you haven't played through an 18" Black Widow, it has a boomy low end you just can't get out of a smaller cone, and the 2 10's round out the sound. It's also bi-ampable.
A couple of tiny snags in the tolex and otherwise like new. Speakers are in great shape. This thing is really heavy and shipping it would be prohibitive I think, so local p/u only.
$200
