I could see Vox doing a small combo amp, 1x12, 2 independent/switchable channels of Valvenergy designed preamps (they are excellent) with a 50+ watt ss output with a quality speaker. Just keep it simple with a reverb and delay built-in, maybe tremolo. Throw in a few output/send options and that's it.
Have one model British voiced -- Mystic Edge and Copperhead channels. American version -- Silk Drive and Cutting Edge channels.
Step up the marketing and get quality gear tubers to demo.
