Hi guys, I have a question about the FX loop.

A) If I want to use the M13 just for modulation effects and use my amp's distortion, what would be right way to connect it and which is the correct setting in the menu? Post all?

B) If I hook the M13 using the 4cm on my head and want to use FX1 and FX2 on front of the amp and FX3 and 4 on the FX loop, the correct setting in the menu would be post FX2?

Thanks!
