I've never seen one of these before - a 1966 fretless 'Devil' bass made by Ampeg, who are now best known for making great Bass amps. It was created by an Ampeg employee called Mike Roman, who pestered and pestered the boss until he was allowed to put them into production. Nobody at the company (or outside it) liked them, and dealers refused to stock them. These days they are very rare, but loved by people like Bruce Johnson, who is now talking about putting them back into production.
