I'm not a Jazz B3 player by any means, although I admire watching and listening to people who do it well.. .....mostly I use the B3 Organ sound etc, with my Arranger Kb's in a R&R songs scenario as that's how I grew up in bands in the 60's, 70's, as a KB/Organ player. Procal Harem, Vanilla Fudge, Deep Purple, Lee Michaels, Spencer Davis Group, Santana, etc..
