1994 Doutone Gut Shots Needed

[Dutchman]

I just bought a 1994 Duotone only to find out the wiring has been butchered. 

If anyone has a USA 3Hole Duotone that they don't mind taking pictures of their innards please place them here or PM them to me. I also need close ups of the volume and tone circuit board.

Also if any one knows of a schematic that would really be cool for the acoustic preamp board.

Thanks!!!

Can't find the schematic right now but here's a pic. I think it is from 4 38677. I'll look again for the schematic later.

And the board;

Thank You!!

No wiring plan here but some more pictures, from a 95er: 5 43150:

Thank's Guys!! I got it all working! The Preamp circuit board is tan on this 1994 model and has some bad tracings. So that's gonna take a bit. Just jumpers for now! 

Thanks Again!!! Another Hamer has risen from the doesn't work  stuck in a closet to a player once again!!!

Perfect! 

Strange the different fourth pot-color of my 95-Model... 🤔

That one is a different value. It's the volume pot. The probly ran out of black ones. All of mine say "Made in Spain" I'm still trying to figure out where the circuit board was made. I do know that PCB's from the 80's had a tendency to be tan. I'm thinking about building new PCB's. I think if I send one in they'll clone it. Then it just add the parts! Surface mount parts...I hate those tiny things....

Wowh!  All respect I only can turn the cavity screws. Good luck 🤞

Hey @Dutchman, let’s see some pictures of the guitar while while you’re incubating on the electronics 

 

thanks, and Good luck

Pictures are up on the message board!

Oh wow, never knew there was that much inside a duotone. What kind of shielding paint did Hamer use for those, anyone know? I've seen a few different colors inside the control cavities.

>I'm still trying to figure out where the circuit board was made.

The green (with solder-mask) and tan (no solder-mask) boards both look to be made by EMG. They are known for being helpful so I would give them a call to find out more.

Yes, these are the EMG HEQ circuit. I wasn't able to track down a schematic, but EMG might be able to help you.

I'd second that.  I've had to email them a few times and they were always helpful. 

[Dutchman]

Turns out they still have them! Who would of thought! EMG IS AWESOME!!
