AJ & Mike, when we look at our old stuff, it's easy to see that we all tried to have quality instruments - not necessarily the best, but in the park. I agree with Mike to a degree that instrumentation counts, but I feel that I could use that Farfisa today and people would still like the sound. The making od music creates its own sound. Horn stabs on a Farfisa sound differently than those on a Tyros, but the feeling/technique a good musician adds to the music is the key.
Starkeeper and others - almost anyone who has the opportunity and option, does eventually use a B3; wouldn't you? The differences between a model L and M were minor additional presets, reverbs, amplification, etc. The basic sound source was identical for all Hammond drawbar organs.
