Structurally mine is great, superb construction, nice neck, what you'd expect from a Matsumoku guitar of the era. Just to looks at it, you'd have no idea anything was wrong with it...however, electronics-wise, it's a mess. As I mentioned, the PCBs are gone, the little red LED low-battery indicator is gone, the pickup selector switch seems to be pooched (and its cavity cover is missing) and there may have been a battery leak at some point. The good news is that the pots and switches that are present seem to be original and in fairly good shape and I do have the MMK53 pickups.
It's a beautiful guitar and ideally, I'd like to restore it, but the electronics are a mystery...I've got some photos of the circuit and there's someone not too far away who makes active circuits/preamps, but he can't determine the values of the components from the images I've been able to find.
Any help you can offer would be most appreciated.
Cheers!
