My latest ukulele is an exercise in versatility: short enough to go inside a suitcase, long enough to be remain playable under heavy capo and, of course, both acoustic and electric. And not just merely electric, but featuring both a passive piezo pickup and a magnetic pickup, which can be mixed in any ratio. I looked for a wiring diagram that could do this, and found nothing simple. They all required a switch to select the main pickup, with perhaps the ability to add a bit of the other, or had something weird about them. Since the two pickups are very different electrically, there was no assurance that they would mix well. I took a guess, and it worked, though theory predicted that it shouldn’t have. Read on for the solution.
