I dont know about the path.
In my opinion, I bought the switch on the recommendation from Geoff Allen at Sweetwater in Indiana.
l am able to combining a CLEAN line for the tube amp; pick a channel from the Line 6 Amplify 150 then blend the two amps into one sound.
It works and with no hassle other than the purchase of the Lehle Switch and a few cables.
Im tired the stereo cable as youre referencing and I too could not get it to work, so I went the next best thing, the LEHLE switch
VOLUME? I used the volume pedal on the helix, no problem. Theres also a wah 486? Its almost as good as the wah I have but I went and bought a newer wah, hand wired. Its volume and fuller in my option, but the Helix is spot on replicating VOX sound. I thought about not using the VOX but Im buying to pass these items along to my kids later down the line.
