I just really dig it because I tend to anchor my thumb on the bridge pickup of any bass that has 2 pickups. This is something I couldn't do comfortably over the years with Rics and has been my only gripe about these basses, being primarily a fingerstyle player.
There are 3 versions. A plain one with no recess or thumbrest (Addison has one of these and may wanna chime in), the 'Cove' (which I have), and another that has a small protruding thumbrest.
Here's info on the different models:

I got mine at Pick Of The Ricks, $36 USD
So here it is.

And no, I'm not giving my '78 Jazz the ol' thumbs-down
