Glad, you sorted thing out for you!
It has worked out really well so far. The POD HD500 seems to be a perfect complement as far as I can tell. I haven't played with it on it's own, but in the loop of the KPA it works perfectly. Like I mentioned I wanted it for some of the odd effects like the synth models. They're great and work really well with the KPA, but an added bonus has been finding that using the HD500's amps with the cab disabled as distortion/fuzz boxes in front of a profile can be really amazing.
