That's a pretty neat idea actually. I do that when I want to have drums on a song where the main guitarAnother option.. play an electric guitar while singing the vocal. Don't record the guitar, just monitor your playing. Do record the vocal. Then add the acoustic over the vocal.
My electrics are so cheap they even call me a cheapskate !!If you don't have an electric, maybe grim will loan you one of his.. ...
Yep. The result would be the same.
But sometimes, a performer needs to sing along to know where they are in the song.
