In Workbench HD, when both Variax USB and 1/4" guitar cable are plugged into my JTV69, I hear crackling noises as the two cables interact with (i.e. rub against) each other. Is this normal? Has anyone else experienced this using Workbench HD? Maybe someone can experiment with it and report the results?
It's pretty annoying when I'm trying to tweak tones to hear this distorted and obnoxious noise going on.
