I saw the title of this thread and when I went to post I saw that brother Jazzy had already posted my intended response. So how about this: the side LEDs also function as a strobe tuner!
And, risking a brief hijack, Gregory’s suggestion of pairing magnetic/piezo pickups is right-on. I just picked up a prototype Wechter semi-hollow with a neck humbucker and Graph Tech Ghost bridge. The combination is a very nice articulate tone. And, getting back to the thread, Alembic has done a few guitars with piezos.
