No picture, but the worst bass I ever had in my hands comes down to a toss-up between two.
First, a whole series of Wasbhurn basses from the '80s. Symetrical double cutaway, just like the guitars they made then. Good wood, necks, electronics, so they should have been nice instruments. But the 34" scale on those bodies made it about impossible to play them. The strap button put the 1st fret about 3' away from your shoulder so standing up was a pain. And the body shape was so small that sitting down was almost impossible too.
Second, a particular Fender Jazz bass. Maple neck with pearl blocks, Antigua finsih, no tone, big clumsy feeling neck, and just about everything done wrong. It was so bad that when people broke into our store and stole a pile of instruments, they left this one sitting in the parking lot. Even thieves wouldn't take it!!
