I recently got a Marshall  CODE 100 and I also recently got a Scarlett 2i2 recording interface. Before my CODE 100, I have been recording my guitar by going straight into the interface and using Pro Tools First. That worked fine. I even have been able to use pedals with my guitar and put that right into the interface. However, I want to be able to tweak my tone via the CODE 100 and still use my Scarlett and Pro Tools First. How do I do this? I do not see a line out on the CODE 100 head (I have a head and a Marshall 2x12 cab).

I am scared to really try because I am seeing mixed comments online. Some are saying it's very dangerous to go straight from the head to the computer via USB WITHOUT having it plugged into the cab because it could blow up the head? Some are telling me the only way to do it is it order a 1/8" to 1/4" cable and monoline it out and straight into the Scarlett interface from the headphone jack?

I cannot find a clear answer to these questions. Please, someone, help me.
