Donny,
I'll bet my sox that this is clearly a guilty pleasure deal driven from boredom, so ... sit back and think carefully. You are not likely to love using a 2 kb setup at home. If you miss the organ drawbars, maybe look for a module that you can sit on your desk, and fiddle with. Simple midi cable from the 670, and a volume pedal brings in the color.

not such a big investment, either
BTW - this is a solid bet, on my end - I don't wear SOX! lol
