There is still a subtle difference. Hammond aficionados can tell the difference between a B and an M, not to mention an X77 or L100!

The Leslie is the final nail in the coffin... A clone into a Leslie (several of them have the multi-pin connectors to hook straight in) can get you pretty darn close, but if you are a true Hammond player, at least YOU know the difference!

I have put a Korg CX-3 (both the old one and the new one) and a Nord Electro2 into a 147 (with a preamp for the old one) and also into a Motion Sound tube Leslie top. Good enough for my audience, not QUITE good enough for me! I'd love to hear a KeyB through a 147...

But, truth be told, barely one in a thousand out front could tell the difference. Then again, they probably think the piano sound is realistic, too!
