That's a good idea. I have used it with the Loop in Stomp A and Parallel path which worked OK but didn't give access to any reverb etc. Now that Reverbs can go anywhere that wouldn't be an issue any longer but the using the loop method I only have one FX slot so Compressor EQ and REV wouldn't work for example. Running the Acoustic in the Aux or with the Loop after the stack would work to some extent but would mean that I would have the acoustic and amp going through the same effects. I don't use many effects on electric but Comp EQ and Rev are sort of necessary for acoustic.
I might play around with that idea a little though. Thanks
Perhaps use an acoustic DI box that has its own effects, then run that after any KPA effects.
