For all KPA owners who still own a traditional amp setup and like to continue using it live, you might like the idea of just using the KPA as a standalone Speaker Simulator. In all that profiling, i was not yet aware of that that really, really great possibility.
Just use your guitar amp and speaker setup as usual. Then connect the effect loop send of your Amp with the return input of the KPA. On the KPA, disable the Amplifier and EQ Sektion, as well as any overdrive or distortion stomps. Then go to any of the stomp slots and select "Loop mono". Now the preamp of your amp is routed before the "Cabinet" section of the KPA. Select any of that great KPA cabs you like. It sounds awesome and will give you a really great and consistent P.A. Signal.
Consider the price you pay for a device like the two notes torpedo. For KPA owners, you get this as a built in addon for free and it sounds even better.
