Maybe it's just the choice of registrations or maybe it's just the player, but I was grossly under-impressed with the (Hammond) sounds of the SKX. I do agree with bill about having sustain on the bass pedals. I don't remember the exact number but I think I paid about $5-600 to add that (aftermarket) feature to my old C3. That was a lot of money back then. In summary though, this would not be my first choice in a organ-oriented keyboard. This is based strictly on my impression of the overall SOUND of the instrument.
