I'm in the process of recording a song. It's 3 separate lines 1 vocal 2 guitar. The main guitar line was recorded yesterday and has sounded fine and the song is pretty much done. I have done no heavy editing, it's all just raw untouched recordings. All of a sudden during playback the guitar part is coming out an extremely low volume but my voice comes in booming. This is extremely frustrating if I have to re-record when it was such a great take. Is there anything you think could be causing this?
