Once I was the proud owner of a Hammond A100 and a Leslie 122. So I know how a Leslie should sound. This piece of equipment does exactly the same. If you close your eyes, it's impossible to tell the difference. Many parameters are adjustable and the possibility to switch between A and B preset is a very good bonus. Want more distortion? Just press the button! Really nice. If you hook it up to a mixing console, do pan left channel left and right channel right (What I initially forgot to do, but still sounded very good). If you hear the doppler effect in stereo, it's as if your head is inside the virtual speaker cabinet! I'm really chuffed.
