The Mi-Si wasn't much trouble to install. I found the center for the endpin hole and started it with a 1/8" bit, finished up w/ a step drill. Drilled an hole angled at about 45 toward the side for the UST in the saddle slot. I followed Chuck Moore's advice and allowed for about 1/4" of dead space at the end of the transducer, which I ran back down another hole at the other end of the saddle. After that it is just a matter of fishing everything through and securing it. I used a 1/4" dowel shoved into the jack to pull the circuit board/jack assembly down to the endpin hole from the soundhole. I taped a piece of wire to the UST and fished it up through the hole in the saddle. I had a problem at first with the pickup wire rattling around inside the ukulele, but I coiled it a ltttle tighter and that went away. It was pretty simple, the hairiest part was drillling the holes in a finished instrument. Charged it up and it sounds really good, better than most piezo-type pickups I've heard. Not so much of that cardboard toilet paper roll sound, but pretty smooth and detailed.
Pete, I'll post a video as soon as I can make one. I found the bubinga a bit difficult to work, and very dense and heavy, but with the spruce sounds pretty balanced. Looks nice too.
