USED.  Tests at around 11 ohms.

Made by Matsumoku for those old vintage Japanese guitars.

Do not know if it is from Neck or Bridge, but it is pretty hot at 11 ohms.

2 wire pickup.

Adjustable poles via allen key.

Comment from online are:

Made by Matsumoku in the late 70's up to the mid 80's. (Think Aria Pro II, Westone, Electra...) Loved and revered by many. Sonically, sounds a LOT like Ibanez's Super 70. I've seen 3 versions: non adjustable slugs, typical slug/screw, and 2 allen key adjustable slugs. I think the dual allen ones were a tiny bit hotter, but that's coming from memory.
I love them in the neck. Bridge is fine, but the neck tone is to die for.
