I took a few minutes to experiment with some VH2 settings on the S970 so that if I ever use it without my mixer I could get a decent VH sound if that;s possible...here is a very quick example using standard Trio,...mind you it's in its early stages of exploration and much more time if I ever get that is needed to achieve what I would be happy with to use on stage if at all vs a Tc Helicon, Digitec optional unit...
