Long story short: my acoustic has two pickups: the piezo and a faux Seymour Duncan in the soundhole and an output for each so I can split them between two effects loops mainly because 1) distortion sounds like crap Thru a piezo and 2) it sounds cool to have an effected tone with a dry acoustic tone under it.
My question: The DL4 has dedicated left/right inputs and outputs. What goes in the left input comes out the left output and vice versa. If I plug my two inputs (say piezo left, Duncan right) into the M13, can I adjust the settings so, for instance, distortion only applies to the Seymour Duncan input and not the piezo?
