Hi, when I connect my M13 to my DT50 using the 4 cable method, it seems that the amp's reverb doesn't work. I have to use an effects bank for reverb. But I was hoping that if the guitar is connected via the M13 and the M13 is off that the controls of the amp would all work.
Would this possibly be because by default the guitar's signal goes into the effects loop? (That doesn't make sense to me, even as I type it.)
