This is a rare DBZ (Dean Zelinsky) Diamond Imperial Bass. I don’t think many were imported to the U. This is the only Imperial Bass I’ve seen with the P. The active preamp creates a variety of tones. This is a premium bass and came stock with a Babicz bridge. What’s most unique about this bass is how thin the body is and how light the bass is. It has a really unique shape and is easy to play. The neck is straight and the action is low. It’s an easy to play bass with a ton of tone. Other than a few dings and a chip that has been colored black, it is in excellent shape. It looks almost new. I can’t find any others for sale, anywhere. I do not have a case or back but will pack it carefully.
