Info: Vintage '80s! Built by Matsumoku! Made In Japan!

This is really cool. You are looking at a Vintage 1980's Aria RS-850 Pro II Rev-Sound Series. Built by legendary guitar builder Matsumoku, the RS-850 is a very high quality top of the line guitar. Produced from 1979 to 1981.
Ok, The story on these RS-850's is that For some incomprehensible reason, in the early 80s, Alembic sent pickups and perhaps electronics to Aria Pro to build their Alembic copy RS850 (the 750 had passive electronics, the 850 had 18v electronics). The specs are identical to the Alembics of the time: two single coils with a dummy coil for hum bucking, neckthru design, 6 on a side tuners, 18v electronics with proper low pass filters with 3 positions for each and hardware that seemed to be a copy of the Alembic stuff. Not sure why they decided to help Matsumoku out, but there it is. So, essentially the Aria is a very similar guitar to the Alembic.

The main difference between the guitars was that the Aria had the wings for the neck thru design made of solid walnut or other wood, whereas Alembic had the wings veneered top and bottom with highly figured woods for a more deluxe appearance. The inlays were very similar. The Rev Sound had a painted on logo vs the Alembic metal badge.
I don't know if that is really true. There are conflicting stories posted on line that contradict each other. The one thing I can tell you is that the RS-850 I have is passive. The former owner replaced the five way switch with a kill switch. He also added individual pick up selector switch as well as an in/out phase switch.
This really is a "Pro Level" AXE. The neck has a great "Feel" to it, the tonal variations you can get out of this guitar is AWESOME! This is a guitar built for gigging
