I've seen other devices have a "thickener" or a "thinner-er" feature to make single coils sound more humbucker-y and humbuckers sound more like single coils. This seems to be mostly an EQ and microscopic fixed phase shift trick... but it might be a nice-to-have tone block for the stomps section.
An all-in-one "adjust your guitar's tone" stomp would be nice. Stuff like twang, sustain, maybe even fret/string noise for acoustic patches, etc.
Since a profile is just data... I don't recall if I mentioned this before - but being able to proportionally blend two profiles into a new third profile would be wicked. While we are at it - why not create an algorithm for capturing one clean profile and one dirty profile of an amp and allow the KPA to track through the middle - instead of adding or subtracting hypothetical gain, actually move into interpolated tones... again - wicked if you can put anything you want in the from and to ends of the scale.
I've been thinking the same thing. Yes please.
