What is interesting to me is the proportions down toward the butt of the bass at the bridge area. Notice how much different the positioning of the pickups and bridge is between the two pics below. That would place your hand at a different place. I like plucking down by the bridge which in the case of that headless bass would make the plucking position further up the bass. I wouldn't like that. I'm wondering if that is a lot of what is bothering you with how the bass "feels". Or is it just an optical illusion?
Very well observed. It is part of the problem - my problem.
