The korean ones are nothing to scoff at, just dont get the budget models. Matsumoku was a magic factory though so it's hard to compare. I have an 84' SB Elite 1 that is perfect. 10+ lbs and I float everytime I put it on.
It is an RSB Special II. It was made in 1984 in Japan so doesn't that make it Matsumoku?
I made the mistake a few years back of replacing the pups. They were single winds and were very treble. The chrome is the best of any APII of that era I have ever seen.
