There is a wav file of the KDFX leslie on the K2500 Zone website. Look in the downloads section.(posted 9240 days ago)The leslie in KDFX is really outstanding. I personally own a Motion Sound R3-147, which is the enclosed rack mount MIDI controlled Leslie speaker from Motion Sound. I honestly prefer the sound of KDFX.
KDFX also has much, much more to offer than just leslies.
