Sorry if the clips don't show a wide enough range guys. I had a customer make those. While I think they are good, I agree they are narrow in the range they show and many sound like they are dialed in similarly. I can see where that would be a non-starter for a potential sale. Unfortunately I no longer have demo units of everything on hand, so making clips is not as easy to do as it once was.
While the MTS business is a tiny part of what we do these days and we no longer invest time on growing it, I can say with pride and confidence that the newest designs like the Z-Rx and VX30 are my best design work. When I had the change of philosophy in 2014 designing the Series 2 mods I produced my absolute best work. Rick testified to that regarding the VX30 compared to the old Voxless. Vox amps are some of my personal favorites and I currently own 7 Dr Z amps, so I really have a great idea what these amps should be. Don't let a single clip on the internet impede you from trying something because I think you will be quite pleased.
