By the way, do you have plans to do either of the following in the future?
More speaker types. V30s are great, but it would be nice to have other speakers, like CL-80s, C-90s, or some neodymium guitar speakers, available. I know that not all of the current "modern" impulses use V30s, but the speakers I listed seem to be pretty popular in the modern metal scene. I think I've only ever seen one set of CL-80 or C-90 (don't remember which) impulses before, so that's something that could be somewhat unique and that I'd imagine would get a lot of use around these parts.
Impulses made with a flat response solid state power amp. This would get the sound of the cab without the tonal coloration of a typical power amp, which would be ideal when power amp simulation is already being taken care of. Of course, I'm mainly thinking about the Axe-FX here.
