I am trying to record Bass and Guitar through my Digidesign Mbox 2. I am DIing the instruments but there is a shocking amount of noise. I know in a studio you'd have to use a DI box but I thought you didn't have to use them in this situation. When I hold my hand over the strings, with the bass it's the G, it stops the buzz. It's really loud if I release making it pretty much unrecordable. My housemate said I need a Pre Amp, but the MBox has pre amps so I don't see how that would help. PLEASE advise this is killing my recordings.
