Hey everyone! This is a forward/repost of my question/request I posted in the Welcome Forum.

I got my Ovation Breadwinner back when I was 12 from my cousin. Batteries corroded, it was in a state. Local music shop got it cleaned and back up and running. It has been an OK guitar for a time, but bit the dust a few years ago. A couple years ago decided I would take it apart and see if I could track down it’s problems. The pickups were shot/decaying and the circuit board had a few traces broken, lifted, and/or corroded (most likely because of the batteries from years before).







With a little know how from my friend and I, we are going to try and make a custom printed circuit board using its current layouts and schematics we found. It will require me to move the components over, but the traces will be newer and hopefully restore the sound of the Breadwinner!

Has anyone attempted this at all?
If not, would anyone else be interested in purchasing a replacement board for their guitar? (it’s cheaper if we buy the boards in bulk!)

Side question, what have people used for replacement pickups that can mount to the Y bracket? I tried contacting Seymour Duncan about a custom Y bracket spun pickup. No response, been over a year.

Looking forward to any responses!

I have manufactured a Y shape adapter to mount different mini HB pickups to Ovations.

Nice! Is that 3D printed? Do you have the STL somewhere?

I think MWoody would likely make it out of wood. But I can't see any of the pictures in thread.

Here's a thread with links to schematics drawn by OFC member BruDev: http://www.ovationfanclub.com/megabbs/forums/thread-view.asp?tid=32...

I'm not sure that there's a market for an exact replacement board. There are several unique components on the board that can go bad- it would be a lot of work to move everything only to find it's still not working.

I'd think about cleaning up your existing board and repairing the traces with a conductive pen like this one: https://www.amazon.com/CircuitWriter-Conductive-Ink-silver-based-4g/... IIRC, I did this on one of Woody's preamps long ago.

To get it up and running quickly, you might look at the Artec line of active electronics. You could put one module in place of the notch filter, and another in place of the tone control. http://www.artecsound.com/pickups/electronics/index.html

Thanks for the great info! Didn't think there would be, but it would be fun nonetheless to design and have one printed. I thought that board was used in many variations of the solid body electrics of that era. My 72 Breadwinner isn't in mint condition by any means, and I think would be a candidate for some simple "sleeper" mods. Might add a kill-pot in it too. I would document everything I do too and post it if people were interested. Might 3D print that pickup adapter as well, or print and process a fancy scratch plate.
