I've got an old Sunn combo sitting around and thought I might get some more use out of it if I ran it with a cab. I am ignorant when it comes to this stuff so I figured I'd ask here. Here's a pic I found on the web of the back of the same amp. http://www.dangpow.com/~sunn/betabass/Img_0009a.jpg I know it's underpowered and old but I figured if I had a clue I could find something used cheap. What do you think?
