Here's a completely different option that eliminates ALL of these problems: Use a Radial Tonebone Bumper Instrument selector (https://www.sweetwater.com/store/detail/Bumper). You can keep up to 4 guitars plugged in and change with a simple foot switch. LED's tell you which guitar is active, and there are Trim knobs for each input to balance gain among them. It has a dedicated Tuner Out. Plug all 4 guitars into the Bumper, then plug the output into the Helix's Guitar In. Problem solved!
