Did you get this bass from Doc Green?
 
Bill, tgo

Classy!

I picked it up through a guitar shop in San Jose, CA. Doc used to own this bass.

Guitar Showcase?  Doc used to work there.
 
Bill, tgo

After scrolling through some old catalogs, I found this. Looks like this bass was the poster child for the Series II in 1983!

Looks like you are right there Neyman.  Also that one right in the photo is a rare example of a light wood neck. Probably maple.

That one on the right has been for sale at Gruhn's Guitars for quite some time. Price may be a little steep, but it's a beauty!
 
Check it out. It's at the top of their bass list:

Checked out the list.  I can now see the reason why it's been for sale for some time. Given the company your new bass has kept, it appears you got a great deal on it. Congrats!

$20.000?
My goodness, that just has to be too much.!

Is this the Doc Green you mentioned? I have done some gigs with him playing at nursing homes!
