New at this but using a impedance DI box is the way i had to go. Not until I hooked one up to my firewire mixer to try to record guitar, my levels had to be way to high. Unlike a mic in a mixer, that most of the time you have to have a lot lower. I am using a older guitar from the 50's so i don't think it was that but just the impedance. By the way got one at a pawn shop for $20. hope that will help.
