As a Hammond Pro Player, my choice in the "New" keyboards MY preference in sound and Leslie emulation, NOTHING comes closer than the Nord Electro.
The only thing is that you must get accustom to the Non-draw-bars user interface, I had the chance to compare it in the same PA (FLAT) with Korg BX3, Roland VK7, Nord Electro, all of these VS a REAL B3 with a 122.
Hands down, the Nord Electro was the better or closer to the B3 !!.
