I just got a used M13 modeler. I love the effects as they are absolutely amazing for worship music. However, I cannot get it working. I tested both cables first and then began my setup. I plugged my amp into its main "input" and into the "output L(mono)" slot on the modeler. I have plugged my guitar into the "input L(mono)" slot. I also did a factory reset and for whatever reason, I can't get any sound to come through. There is a dry noise I can hear but nothing from my guitar. The tuner also isn't picked up on anything but when I turn the modeler off, I am able to play through the amp. I am so new to this type of setup, any feedback on how I might solve this?
