Hey guyz...
Don't know if this has been mentioned, but if you have a POD HD500 and you run the Kemper INTO the POD's FX Loop (and not the other way round) then you have full use of the Onboard Looper with Voice Changing, Recording and everything. You can also have three Guitars / Basses and a microphone (Guitar In/Aux In/Variax/Mic In) plugged in at the same time (if you have Variaxes as I do) plus use the HD500 onboard FX in both Pre and Post modes. Oh, and did I mention full MIDI control over Patch switching (Nos.1-64 assigned), Stomps 1-8 and Wah / Volume control. A great combination all round - gives you infinite FX combinations with more being added all the time...
