I've got a pre-serial 22 602, and it is something special....but it rarely makes it out of the bag.
For all the soft, complex jazzy tones, great ability to build, crash lightly and sustain a constant sticking....it just isn't very cutting and not at all loud enough for any type of amplified music. I see it as a piano jazz thing, and i just don't have that going. So it sits.
Like a lot of us, i listen to the old A's i recorded with, but now have sold, and wish I still had them.
