WOW - just WOW!!! This thing kicks butt. Kind of figured most of the subtleties from one clone to another were lost when running through real Leslies. But B5 is clearly several levels above the XK-3C; thicker warmer . I really like the key click and the vibrato/chorus. Won't comment on the various sim Amps and Leslies other than there are a ton of choices and lots of flexibility with each of the Leslies.
Best of all is the customer response to issues. I've had 2 bugs resolved with new versions downloaded to my account within a day or so of reporting. And got one more confirmed and on the way. Pretty damn fantastic all around!
