odd 72 thinline - need help with wiring

ezrydr · April 27th, 2008, 09:54 AM

I am going to continue my original thread for this guitar here on the tech page

http://www.tdpri.com/forum/telecaste...-thinline.html

Now that I have the original pups back in the guitar I am having tone pot issues. Basically the tone pots no longer affect the sound. Volume pots work fine.

I was looking at the original wiring diagram from the Fender web site amd noticed that my original pickups do not match what is shown in the diagram.

Note how the diagram shows 2 wires within the the shield coming from eaxh pickup. A brown and and a black.

My pups only have 1 wire within the shield.

Can anyone explain what the deal is here?

I was going to try and reqire the guitar back to original but now I find the original diagram does not match my guitar.

I'm a little confused here. Your guitar has four pots not two like the '72 thinline diagram. Seems like you would want to wire it like a '72 Deluxe or like this Seymour Duncan 2 Humbucker, 2 Volume, 2 Tone diagram.

With respect to the fact that the Fender diagarams show an extra wire coming from the pickup, notice that two go to ground and can be thought of as a single wire. Same with the Seymour Duncan diagram. Think of each pickup having two wires ............ground and hot.

"I'm a little confused here."

welcome to my world!

After I posted the this thread I toolk the guitar out to my shop along with the original diagrams. After I sat and scratched my head a bit it dawned on me, exactly like you said, that the diagram is treating the shield/sheath as a separate wire. It really is not drawn correctly in my opinion. But I get it now.

Since I really want to keep the separate controls for each pup I rewired everything to match the 72 Deluxe.

Everything works fine now. Tone pots work correctly, sounds better and got rid of a slight hum.

The way the guitar was wired was nothing like the original. I can only assume, since I do not really know, that whoever did the original mod was trying to duplicate the wiring in a Gibson.

Thansk for your help Jack!
