Is using an RJM Mini Amp Gizmo the only way to ensure the Helix functions properly with the Mark V?
I would like to purchase a Helix and use the 4CM with my Mark V but unfortunately reading this thread makes me think the FX8 is better suited. RJM is not available locally, perhaps the Voodoo Lab Control Switcher will work? To clarify, my aim is to just be able to switch between the three channels from the Helix, with no ground noise.
