Oh, oh! I think I got it. This was the bass that Leo actually build to the Ringo Starr specifications. Ringo wanted that now infamous mudbucker sound that could only be produced using the famous St. Paul pickup custom made by George Peshaw, and they were only available through Pete's repair shop, so Leo after lovingly hand crafting his first personally made instrument in 15 years sent it there were the mudbucker was installed. Unfortunately Ringo had no rhythm and picked up the drums instead.
