Hello. I have a guitar processor nux mg 400, and a sound card behringer umc 404HD. I want to record electric guitar through my guitar processor connecting the unbalanced outputs of the nux mg 400 to the combo inputs of my sound card. Here is the question, do I need a DI box? My sound card has an INST button, but do I need a DI box just to make the signal balanced and not unbalanced? The jack cables are high-quality, but long. And I do not play far away, I play close to the sound card
