oh yeah!  This would be an awesome feature!  YES PLEASE.

Not sure if the hardware would allow this?

an AMP or CAB factor pedal would be nice.  I've never used any of eventide's rack gear but Im pretty sure at least the H8000 allows for fully customisable algorithms although you probably need to be software guru to drive it….

Im sure there are other goodies that could be ported from the H8000 to H9….
