The title of the thread kind of lays it out there. I have an Op-Pro that stopped putting out a signal. I have no idea why. The tuner still works, but no signal out at all. I also know it's the unit and not the can as I swapped it into a functioning guitar with the same results.

John Budny kindly replaced it as it was on one of my guitars they re-built, but it seemed like a waste to just pitch it back then, and I have since found a use for it if it can be made to work again. The old OP-24 is going bust on my trusty Custom Balladeer 12-string.

So is anyone here handy with these things? Electronics are not my forte.
