Speaking of those pickups......I noticed that this one has a screw through the middle of the hum cancellor. I would think that this would render that unit useless. If that is so, one would have to settle for a black one since that material is no longer available. Maybe Alembic did that originally. I would feel ok about that. I have seen others this way too. On all of the real early ones I have, that is where the batteries are located. The hum cancellor is inside the instrument. Could be that on the early ones with the dummy pickup on the front, that they were actually screwed in place instead of glued. Anyone over there remember?
