You can do a HELL of a lot with this setup. I'm running the piezo output on my Carvin (seen on wall in background) into the Return Input on the back of KPA. I use the mono loop to mix it in for acoustic only, or acoustic/clean patches. Works like a dream (songs like AIC 'Down In A Hole'). Next step FRFR!

Looking good - what kinda price?
