I'm not too impressed with that demo. I own the Roland Vk8m tonewheel simulator which is supposedly based on COSM, and the tonewheels in that sound much better than the G70.

I think I also heard from Roel the leslie Sim only has the lower rotor and not the upper horm? I don't know if that's true or not.

The VK8m has lots of amp settings to make things nice and dirty. Maybe digging deeper in the G70 will yield some surprises.
