I would like to use my Line 6 Relay G50 with my AxeFX II XL. I ma having an issue where when I attempt to use the wireless unit, I get a weird single-coil type of top end. Like it is adding springy high end that I cannot dial out. Any tips or tricks to get cabled sound from a wireless unit on the AFX? As a side note, I also tried my old Nady wireless (from the early 90s) and had the same results. I am running humbuckers in my Charvel SoCal.
