Just to be absolutely clear, even though the legending on the front of the Profiler begs to mislead, the Cab is always last in the signal flow. It also makes sense, if you think of real-world equivalents; as guitarists, your delay/reverb pedals/rack FX would still be outputted through your (stereo) guitar cabinet(s). Having these things after the cabinet would mean outboard in a studio or at front of house, which is something that the KPA isn't attempting to emulate.
I find this hard to believe, SamBro'.
I haven't specifically listened out for it, but I would've thought that if delays and 'verb (and space, for that matter, which obviously is post cab) were emitted from the cab I would've noticed.
If they do indeed enamate from said boxes, I hang my head in shame 'cause as an AE it's something I should've noticed, no doubt. The only excuse I can think of if this turns out to be true is that I've generally had all FX and stomps locked off whilst my brother (Fingers) played his heart out and I scroll through the smorgasbord in RM.
