Hi,
Well, I've only just ordered my KPA and I'm already considering what it can't do. Mostly I'm thinking I'll probably need a foot controller though I could probably utilize my spare Behringer FCB1010, but floor space is tight and I thought it might be nice to add in some sort of pedal based guitar effects to the mix that could also be used as a controller and even possibly pick up where the Kemper leaves off in terms of a preamp model who's tone controls are actually representative of the gear modeled. Maybe I'm unjustifiably afraid of this limitation. I'm wondering if anyone uses something like a POD HD 300-500 with the KPA and how that went.
