If you MUST have an authentic sounding Hammond B3, just 'pick up' a re-conditioned unit & try moving it. The next best thing of course is Native Instrument's B4 software, but that means (at least for gigging purposes) bringing along & hooking up a fast laptop as well. The Yamha Tyros' Hammond B3 sound may not sound exactly like the real thing, but its certainly impressive to my ears, especially when you utilize CD-Soft's huge IMPRESSIVE Organ voice collection.
