I have always played at least 50% L/H bass, but since I got my new little Hammond SK-1, I do about 90% left hand.

I still play 2 nights a month on B-3 for jazz night, but, lately, the pay barely pays for the maintenance.

To keep from falling asleep, I use a Hammond on the bottom, the arranger on the top and a variety of 1 or two keyboards on the right hand. That way, the right hand is the prominent lead instrument, and I can either use Rhodes, Wurlitzer, acoustic piano or synth sounds.

The extra work is well worth it!

Good topic, Fran.
