Any Hammond emulation involves compromise. The trade-off for the lack of drawbars is the extremely light weight and small form factor. I still own my XK System and for larger gigs (ie, gigs that involve more money and more "prestige", for lack of a better term), I will still use it. The SK2 is perfect for gigs where the backline is less than optimal and/or I'm flying to the show. At 35 lbs, I can put it in an ATA case, which will add another 20 lbs at most, and check it on any flight for a small fee.
With that out of the way, the SK2 arrived today!
I've been playing it almost non-stop. My initial thoughts: 1) It sounds far better than the XK3. Better percussion, better chorus/vibrato, better Leslie sim, better key-click. 2) The action is quite different than the XK3. It's going to take me a bit to get used to it. 3) It is so small, but still feels solid.
Here's an example I did this afternoon. I took a song that organissimo recorded as a sound-check / mic check / warm-up for our latest CD, muted the real Hammond track, and recorded the SK2 direct. No compression, no EQ, no special effects (except for a bit of reverb to help put the SK2 in the same "space" as the rest of the band). Just direct off the outputs, using the SK2's Leslie sim.

I'm really excited about this new instrument. Videos and more to come soon.
