OMG, It looks like one of those things you see with a baby attached! You can breast feed while you play! (sorry, just had to say that).  
 
I also sometimes play a ss series and got used to it after a week or two, but I do play it up high.

That?s funny Dave!  
   Sort of like a Papoose, you can get so caught up in the mechanics and solutions you can forget how it looks!!  
Still there maybe something here if there was a way to combine the system to a single one shoulder style. Anyway over thinking again. Thanks for the laugh!

Here is one I found today that may be more suitable and less intrusive but not sure if it would solve the forward lean of the bass.

There's an Alembic part of the way down this page.

I saw this on facebook today, one solution from bass player Stephen Jay for neck dive on a sc signature bass. Not sure if his page is public but if it is you may have to log in to see it.



Neat idea, though probably fiddly to get the bass off at the end of a set or changing basses mid gig.

It is a unique solution. I'm not sure about fiddling around that area of the body to hookup in public though.
