I'm thinking that an Orange/Matamp-based line would make a good addition to the Ceriatone kit list: there are several amps of interest, they differ from the current offerings, seem to be relatively simple, and may have produced some of the more notable historical tones.  I'm not talking about any of the modern Orange amps that I know of, but the ones from the old days as used by Wishbone Ash, etc.

The Ceriatone kit is not a close representation at least of the 60s JMI Voxes -- it would be GREAT if they'd make those though; the AC30/6 and the models before it are the amps I'd most like to see added at Ceriatone.  That and a Marshall Major and a Mini-Major if a solid design can be had, transformers are available, etc.

Another thing that would be nice would be an SVT, and a nice version of the old biggest and best VHT power amp would be super.
