Someone responded to one of my Cl ads, and said he wanted to trade a Ampeg BA210 for one of my basses. While I didn't leave with the amp, I left with a Tascam 4 track portastudio and.... A Hammond M-102.(I think) Well, I didn't actually take it home, it wouldn't fit in the car. I don't know much about it, aside from the fact it works. I don't know much about electromechanical organs at all, so, can someone explain them to me? I'll add pics when I wrestle it into my house.
