I'm good with a good B-3, a natural piano, a Rhodes,a flute and maybe a coronet. to keep things interesting, I often use two keyboards, and change up the top one for a variety in the lead sounds. Right now, I'm using a SK-2 61 note Hammond. Two weeks ago it was a Yamaha NP-20. Before that, a Roland AX-09 Lucina.
Fun, if you remember where the stops are.
