First of all, yes cassp, the XK-3c is marginally less expensive than the C1, but not (by a WIDE margin) after you add the second manual. Plus, how much does that whole combo weigh...?
I am still utterly amazed at the total about face by many on this post about the importance of weight. Here is a DUAL manual Hammond clone (stop nitpicking 'drawbar clone' references... that's all they are, references - Hammond still have the rights to their name, or all of the manufacturers would simply call them Hammond clones) that weighs less than many of our TOTL SINGLE manual arrangers.
Dual manuals, for anyone that actually PLAYS a Hammond, unless you are just some multi-keyboard neophyte that only ever plays on one manual anyway (that's the telling difference - most guys with Hammond's or Hammond clones in their rigs only play the one manual at a time. That is NOT a B3 player, IMO) are mandatory. Otherwise, you are just 'faking' a real organ part.
You look at ANYONE that has made the Hammond sound as part of their 'signature' sound, they play BOTH manuals. Rick Wakeman to Keith Emerson, to Benmont Tench, to Jimmy Smith, to Groove Holmes. If you don't play BOTH manuals, you are, IMO, just 'playing' a Hammond SOUND, not 'playing a Hammond'. That's like saying that, because you have a sax sound in your arranger, you are a sax player!. Or that, if you only have 61 keys, you can play a REAL piano part.
The physical size of the original instrument defines what the 'sound' should be, as all it's greatest players used those limits to define what could (and couldn't) be played on it.
No, sadly, what we have here is a bunch of ARRANGER players trying to critique an instrument they have never learned. Now, I KNOW how bent out of shape you all get when someone who obviously isn't an arranger player goes ahead and reviews an arranger, and totally misses the point... I see no difference here.
The fact that professional organ players are happily using the C1 on major tours, while a bunch of mostly weekend warrior arranger OMB acts are criticizing it is VERY telling.
