Ideal would be an SM/SMX mashup. Dual compressor with 7 band EQ. And there should be a "half shape" setting that is a more subtle scoop. Or a shape knob with that same curve but controlled continuously. Ditch the mid boost shape.
The 410 was always the best cab but nobody wants a 100lb 410 anymore. Get that great punchy sound some other way.
Hmmm...
Actually yeah, the old 7 bands would make a lot of sense, if the ELF were to get a beefed up version, over the 5 bands of the Transit-B.
The 4x10 was a great cab - especially live, but the Fane 15" sounded even better for recording. These days though, there need to be lighter options available.
Replacing the Pre-shape switch, with a continually variable pot is a great idea - but I think it would be fantastic if it were flat in the middle / classic Trace pre-shape at one extreme / and mid-boost at the opposite extreme.
