I've owned 2 Studio amps (and a Sustainor pre-amp) in the past, and they were certainly unique in that many different parameters could be adjusted. At the time that I owned them, they were the only power scaled amps around as well. With the right settings, I was able to get some pretty convincing Vox Fender tweed, and Marshall tones from the Studio. I'm more of a plug and play guy at heart so I ended up selling them and going with a Stephenson amp. Kevin is a great guy and helped me out a lot when I was tinkering with my own amps. I have no doubt that everyone on the list will get their amp. Hopefully Kevin can lock in on the design and get churning them out.
