SK1 arrived last Friday and has been incorporated into my rig. Using an FC-7 pedal and an old footswitch for Leslie control.
So far I pretty much agree with most everything I've read pre-purchase. Looking forward to digging in but had to press the SK1 into duty after only a couple tweaks (polarity reverse the expression pedal, using the 'noisy' tonewheel set, etc). The biggest disappointment as others have mentioned is the overdrive, although I do appreciate how it 'behaves' with the expression pedal. Also think the 'drawbars' are much ado about nothing seeing as how they aren't 'real drawbars' by any stretch of the imagination...I think the case could be made that the Nord Electro button method might be superior only because you get a more accurate read of what you're registering although the aesthetic is different. I see what they were going for there, but when I think 'real drawbars' I want/expect the satisfaction of the clickety-clack as you move them. A small gripe but more of an annoyance with the marketing.
Again, since I pressed the SK1 into service so quickly, has anyone figured out if we can trigger authentic Hammond reverse-key presets (say from another keyboard), or if they're available in a menu somewhere? My apologies if this is in the manual...that would be a sweet feature
