this is the earliest one I can find that has the filters wired to be on all the time
 
Mica,
I'm trying to follow wires, but I'm confused. Do the Filter Freq & Q knobs sweep each pickup simultaneously? Or is the signal summed and run thru the filter parallel to the direct signal?  
You're referring to the circuit in the plural, but I'd imagine you'd need quadruple stacked pots to pull off my first guess?!???!?

Anyone know where to get a couple of those double bar knobs? They would be perfect for my coil selector rotary switches on my Starfire!

Complete with a letter from Bob Weir stating the guitar was made by Doug Irwin?!!!!!!  WTF!!!!  
 
Bill, tgo

Hi Bill, this Letter of Authentication was written before I had come across this site and learned more of the history of the guitar. On the home page of our website and in the eBay auction description of the guitar I include Ron Wickersham, Rick Turner, and Frank Fuller.

I think I might recognize it if I saw a picture of it. It looked a little like #12 as well ! I Have always wondered what happened to her Bass . Do you still have your 72 ?  Do you know who owned it before you ? . I Think you might guess where I am going with this !   Got Pics?

Wolf — is the Mouse you referenced Markie Sanders/Shubb?

I don't trust this, as it is from AI, but possibly Mary "Mouse" Johnston - later Mrs. Rick Turner.
