Riverhead Jupiter Bridge Adjustment

[dadadata]

I have a "Jupiter" that was de-fretted and stripped to bare wood by a previous owner. It's a nice instrument.

However, I don't understand how to adjust the bridge. And I've been playing bass since before the Badass came out.

So I know how to set up all varieties of Fender bridge, Badass bridges, Univox fake Mosrite bridges, Gibson LP Recording bridges, and Rick O'Sound bridges.

But this one has me baffled.

There are three screws on each bridge piece. One, obviously, changes the string length.

If we can figure this out I'll do an illustrated tutorial for everyone's future reference.
