Newbie here! I need to record my electric guitar onto audacity and need some advice on audio interfaces. I'm thinking of buying a line 6 pod HD500 and this has an audio interface on it. Would there be any difference between an audio interface that I would buy seperately and the audio interface built into the pod? Also, the pod has amp modelling so would this sound much different to the sound comeing through a seperate interface? Thanks a lot.
