I've had this Series 1 guitar for over 10 years.
  I've started thinking about getting it back to as original as possible.
It appears it possibly has mellow filters (two extra switches close to the bridge).
 
Thanks in advance for additional info.

A '78?  Cool!  Well, you've been around here long enough to know what we're all thinking now:
 
Gotta post some pics!!!!
 
Bill, tgo

I'll start a showcase thread with pics.  
It's a cool guitar , but it's had a hard life.
I'm thrilled at the idea of getting her back in the game.

Ergh - no file. Will add details when it turns up.

ah well...thanks just the same.
I sent you an email (in may or june) with questions as I figure out it's restoration. If it got zapped I'll send another soon.  
 I know I'll need new pickups and maybe more.
