I actually set it up and worked with no apparent issue. I am waiting for some new cabling to come in so I can wire it properly. I will try and make a guide for what I did when I have it wired properly as it appears this is not a common setup idea.
That’s a really interesting idea. I’m using a Rocktron Patchmate switcher and I’m using the ModFactor prior to my FX send so the wah sounds decent. Only thing that would concern me is the mismatch between the signal level. You have to choose guitar level or line level on the ModFactor and it’s universal on both inputs and outputs, right? I almost bought TWO ModFactors for that reason.
