Feature:
- Very editable - Great Leslie simulation - Leslie settings are stored with each preset which means I can configure it to mimic several B3/Leslie combinations and save them with each patch...very nice! - The knobs & drawbars send PROGRAMMABLE CC messages, which means I can set them to control other devices. I set them up to operate the B3's controls in the studio...very useful. - Nice keyboard with fast action - Did I mention how editable it is???

Quality:
I think it's well made as far as the case and electronics go. My major complaint is the finish. It attracts dents, scratches, and nicks. It also starts peeling off (like that bad shelf paper my parents used in the 60s...ouch!). What's up with that?

Value:
It's expensive, but I a b-stock with a few minor dings and saved myself $350.

Sound:
Picking a B3 clone is a very personal experience, and you really have to spend some time playing and tweaking all of them in order to find what you're looking for. I've owned several of them, including: Roland VK-7 Roland VK-8 (two of them) Roland VK-8M Native Instruments B4 As any B3 lover knows, there are a lot of variables that go into that sound, including the tone, leakage, C/V, key click, percussion, Leslie, reverb, distortion, etc. The reason I went clone shopping in the first place was to get all of those features in one place. Naturally, you won't find one clone that does them all perfectly. At some point, however, you find a sound you can live with and you go for it! For me, that choice was the Korg CX-3. I am particularly picky about the Leslie simulation, as I do NOT want to carry a Leslie around...the CX-3 does a superb job!! The Roland VK line does a lot of things well, but their Leslie simulation can't touch the CX-3's. The VK-8 is also very difficult to edit, and you never know exactly which "value" you are setting a parameter to...it's a NIGHTMARE! The CX-3 is deeply editable, and you always know exactly what you're setting. If I had to complain about anything in the CX-3, I would zero in on 3 areas: - the C3 setting is a little too heavy for my tastes - I wish I could get the Leslie rotor ramp down speed a little faster - the EQ settings (particularly the midrange) are not what I'd choose to bring out the best sound in the CX-3. A proper Leslie demonstrates a peak at 2.5KHz, but the mid EQ settings on the CX-3 obviously don't accentuate that frequency. An outboard EQ is necessary. Other than those things, the CX-3 is king!

Support:
I haven't dealt with them, but they did release a major upgrade to the operating system (2.0), which added a number of new features that I really found useful.

I love the Hammond Tonewheel Organ...period. I've played lotsa Wanna-B's, but the sound was always lacking. Perhaps they were too perfect, too much like what Laurens Hammond would have made, had he had the technology in the '30s; or maybe they just plain sucked. Either way, no other clone has made me just giggle when I play it...no other clone has allowed me to close my eyes and hear the 300-pound beast growl, sing, scream, and whisper all at once (though the V5 did an admirable job)...no other clone has been so imperfect... Frankly, the new CX-3 just kills. I gave it a 4 for value simply because it's so expensive...you could pick up a real Hammond (probably not a B ^_^) at that price...though you couldn't actually pick it up....another handy feature of the CX-3 (it's only ~35 pounds!).

If you're serious about your organ sounds, want something amazingly close to the real thing, and want to gig with it without killing yourself or your friends, then the CX-3 is it. Go ahead and wait till you have the cash to get it instead of getting a cheaper clone now...you'll thank yourself the first time you play it.

I love my C3/Leslies, and will never again part with them...BUT...this is the first non-tonewheel piece of gear I've ever played that made me think I was playing a real tonewheel machine. The organ sound is spot-on nailed...the Leslie simulator is by far the best I have ever heard (90% there...if you can, listen to the Leslie simulator in stereo...you can hear the rotor sweep from left to right, just like a stereo double-miked spread)..the overdrive is sweet, and the chorus/vibrato is the frosting on the cake. My only gripe...the keys, though good, are still not as swipable or smooth as the real thing...but they are still miles ahead of the XB-2/VK7, or even the XK-2. No, I'm not parting with my C3 for anything or anybody...but...I'm not going to haul it around, either. But hopefully, I will be hauling around a new CX-3 before this year is over.
