"Licensed to Aria by Alembic" according to the ad.

The Aria Pro II RS (Rev Sound) series were certainly inspired by Alembic. The higher end ones even attempted to copy Alembic with active pick-ups with a dummy in the middle and filters. However, they did not use Alembic PUs or electronics. And I don't believe they were ever "licensed" by Alembic. IIRC, Alembic did work with Aria on a Rudy Sarzo bass, supplying the PUs and electronics for that model. The eBay guitar is cool. I have the RS-850 model. Nice guitar, but definitely not in Alembic's class. Also, the one on eBay has been modified to add the Floyd Rose.
Bill, tgo
Bill, if only it were (or better yet, if they'd have skipped installing the dive-bomb wiggle stick): It's a Kahler, top-mount. No rout-through on the back for the block and springs. It's amazing the Matsumoku-vintage market is growing as folks realize what gems came from those days from 'over there'.
Your are correct, Joey. I didn't really look close, sort of like looking at a car wreck! Once I saw the locking nut and the rout for the original reverse bird tailpiece peeking out from under the bridge, I had to turn away. And don't get me wrong when I say it's definitely not an Alembic. It's still a well built very nice guitar. The RS-850, the most Alembic-like, came in two versions: one with a 3+3 headstock, and another with a 6 in-line. They also had a bass version.

No license to Aria for building anything - but we were good friends with Mr Arai, and sold them pickups and electronics for other models.
I own am Aria Bass with "neck through" design, that has such Alembic pickups and electronics in it as well :)
