NOT A DUMB QUESTION AT ALL. Sadly that amp has been modded and is not worth 1/10th of market value so chopped and molested. I do have a soft spot for those amps, so I'd be willing to offer you half what you paid.
I'll give you what these Cat's are giving you, plus sweeten the deal by throwing in either a Crate or Line 6 amp, your choice.
ya know ya want the ribs....
