Emu B-3 Organ Module For Sale. This module was designed to sound like classic a Hammond B3 electric organ. It will cost you a small fraction of what a real Hammond B3 costs and is about 99.9% less likely to break your back when transporting it to gigs. We'd keep it for our studio if we were into B3 sounds, but we're synthheads here so we have no use for it. Fully tested, working great and looking great, as you can see from the pics.
