Next week, I'm getting a Zoom Q3. I want to make videos to put on Youtube and for practises and stuff. I want to have the song playing in the video and my playing on top at the same time. Which would be the best way to go about this? Just play the song and record it at the same time as me playing or listen to it through headphones while playing so only my guitar gets recorded then somehow layer the song on top of the video after? I have no idea :/
