Hi,
if the looper you choose only has one input/output for a given send/return loop, you won't be able to use the ModFactor in stereo. What I'm trying to get at is, if for some reason one of the features on your ModFactor doesn't work the way it used to before you had it in your bypass loop, we can't be held responsible; there are many bypass loopers out there, it'd be impossible to try and predict/build the Factors to work with ALL of them. In reality, you should be fine, but you may lose some minor functionalities.
