Of course if you feed a fake Hammond sound into a real Leslie it will sound more authentic. That is because the cup now contains at least a 50 50 mix of real and instant coffee. The Leslie may even make it 75 25. The combination of amplitude modulation and doppler cannot be completely simulated from a stationary speaker not to mention the fact that the rotating speaker sprays the sound off everything in a 360 degree radius around the room.

I actually have a RotoPhaser. I think that is what it is called. It is the rotating horn speaker. Even that is too heavy to lug around. I should sell it. Maybe I should hook it up to the X1.
