John:MJ, both the mic and guitar plug into the VL2 and then just a single XLR (mic cable) goes into the USB interface to my laptop. Once you set the overall gain on the USB interface, you can control the mix from the VL2. A foot switch on the VL2 switches the harmony on/off. It's great for live performance.

Thanks for the feedback. Darn cool toy there. I will have to learn more about the mixing and recording first....
