I have a Pod HD 500 -- Anyone know of how I can use a POD HD 500 to process a recording guitar that is just a clean guitar signal (run thru pre amp, not effects) Guitar Rig has a VST plugin that lets one do what I want, but I like the tones of the POD much better--but, I can't figure out how to input the clean guitar recording to the POD for processing Any advice/suggestions, greatly appreciated
