I started playing professionally in the mid 60s using a model A Hammond and twin tower 31H Leslies. I didn't know what power I had back then, being a snot nosed teenager. In retrospect, I will probably never repeat, in digital fashion, that power, "thickness" and sheer "Hammond" sound that seems to evade--in purity--the manufacturers today (although they are a lot closer than the cheesy stuff that was being produced until a couple of years ago). I recently purchased Kurzweil's PC3 after hearing some Hammond stuff it emulated on YouTube and was impressed. Kurz has always provided high quality acoustic sounds. Their pianos and strings are unparalleled in the digital board market. That plus the allure of having 1000 factory sounds and all sorts of tweaking capabilities drove me to the PC3 and, for the most part, I am happy with the investment. It's half the price of a Nord C series and IMO has
much better pianos. The drawbar-sliders also make for realtime associations with the Hammonds, and--for the first time in my experiences--the Leslie(s--there's tons of different cabinet styles settings in this board) are as accurate as you can get without dropping almost $500 for a Neo Ventilator (why can't Kurz' build that technology IN to their boards?), although the common issue with on-board simulators is somewhat evident, that being a doppler/phase shifter-ish sound on the FAST mode of the Leslie effect. The fast-to-slowdown, to chorale, however is very effective and realistic, and leakage plus distortion levels are adjustable and save-able as well.
I play in a Bob Seger tribute band and lots of his music is meat-and-potatoes keyboard stuff: primarily acoustic piano and Hammond. The PC3 hits on all cylinders in this department and for gigging with one keyboard, a monitor amp, a small mixer (for mixing down my two inputs before sending to the mains), I don't think I could get as close to a complete package like this with any other equipment, all things being considered.
Bottom line: If you want just ONE board that "has it all"--at least "enough all" to not feel like you have to have more than one board for performing or private enjoyment, I don't think you can beat the PC3.
