I recently got this bass and was having a hard time getting a date. The story I have puts the guitar being played in the 60's. It has a silk screened serial number. #155652. From the pics I've seen on the web, this ones missing the hand rest (steel cover over strings). I believe it to be a eb 0 but I've been wrong before. Great shape. I did see pic of guitars with a dampener by the bridge this one appears to never of had one. 1 pick up with a volume and tone knob. The lower finger rest is there. Theres nothing on the truss cover. I hope the pics can do most of the talking. Any info or date would be great. Thank You. I only attached 2 pics. It took me an hour to figure out how to resize, lol. I'm sure it's a mess. I can add more.
