Ok....after running a test you are correct. It selects "Stack Power Amp" as the default Output mode. Thanks. Additionally on a side note, with the introduction of the HD500X having a new foot switch design and faster processing cpu, I am curious if there is a new FBV in the works that would operate the HD Pro nicely and perhaps an upgrade for the HD Pro? I currently have the FBV Long Board I have used on my PodXT Pro however it is not a user friendly for the HD Pro, a bit of a disappointment.
