This is another one of those guitars 'lost in the shuffle' as Japanese marketers relentlessly rotate their product mix over time. Others on this list:
Yamaha SG range
Yamaha AE jazz boxes
Aria PE's
Yet strangely, some stay around: The SA2000/2200 Yamaha 335 guitars (IF you're open-minded, don't EVER be in the market for a 335 and try one of these, they had Larry Carlton and Dean Parks fine tune them, you'll HAVE to own one), the Ibanez George Bensons and Scofields, I always wonder if these are favorites of the executives . . .
Anyway, great find, great axe, Congratulations.
