I believe they died in the 80's, along with perms and spandex...I've tried finding stuff about them a long time ago when I first got into Becker and Cacophony and came up dry..
The only thing I can tell you is that they were made by Morris Instruments in Japan in the 80's and there rare as fuck, although they do come up on ebay once in a great while, and actually go pritty cheep, or have in the past, I don't think theres a set market value for them, there worth what someone willing to pay basically. Theres 2 Hurricane basses on there now, but I have a fealing there a bit more common.
