Okay so I'm wanting to get a re-amp box. Probably an X-amp. But Here's what I don't understand: whenever I see a diagram of explanation of how to use a reamp box, it goes like this, Guitar - DIRECT BOX - Computer - Reamp box - Amp Now what is the direct box doing (what is a direct box for that matter), and why can't I plug my guitar straight into my digi 002 and then put the clean signal out the reamp box to the amp? I have a feeling I'm just very confused and if someone could explain the steps and what each step is doing to the signal it would be greatly appreiciated. Sorry for the n00b question! EDIT: Hmmm.. does the direct box change the impedence or something? like, from an instrument cable to a XLR?
