I am fairly new HD500 user and this may have already been covered. Here's my situation.... POD HD500 with Marshall ma100 h (tube) + Marshall Cab. GUITARS...LES PAUL< STRAT styles. I would like to use the the marshall's master control...ie Volume to control sound levels. I enjoy using the amps within the POD SETTINGS as well. How can I have the best of both worlds?? In POD EDIT where should the loop go and how to ajust the settings so the amp and pod work together?? Thanks for any advice!! :)
