I know they were made in the '80s, and for a time both Eric Clapton and Andy Summers were endorsers, though I can't find any official documentation. (The 30-day warrantee made the decision that much easier.) I've tried to research the amp's history online, but there really isn't much information. It sounded great when I tried it out in the store, so I figured I'd take the gamble and bring it home with me.
I was hoping you could shed some light on a 60-watt tube head I recently acquired from a local pawnshop for $140: a Dean Markley Signature Series 60 head.
