Greetings. I just ordered an M13 and have a question about hooking it up when it arrives. I plan on using the 4 cable method, and also a couple of external pedals. I will be going from the guitar to a compressor, into a volume pedal, and then the M13. I aslo have a DigiTech Trio and JamMan Solo XT, and I am usure of where to place them in the signal chain. Should they be placed between tha amp's FX Send and the M13, or between the M13 and the Amp's FX Return? I attached a pic of the cabling diagram, so hopefully someone can point me to the proper place to put these two pedals. Thanks in advace.
