Hey all, I know this is a common topic but I still haven't found a satisfying answer so I'm going to ask it...   How can I remove the tone coloring that occurs on the HD500X when in stompbox mode and all effects (and amp models) are OFF?   I can tell when I go to the tuner and use the bypass mode that with all effects off, the 500X is still affecting my tone. In tuner bypass mode, the signal to amp is dry and unaffected do the 500x *should* be capable of not coloring my signa
