That’s new ! Now you can play guitar, and don’t bother to make guitar faces. The guitar makes the guitar face for you. I mean, if you’re gonna be playing the blues, might as well look like you’re really feeling it, right? So, why wouldn’t that be a shared burden between you and your guitar?
Or maybe it’s just a way to say “let your instrument do the talking!” Of course, what better way to do that than with a giant mouth, ready to gobble up all those sour notes. But is it just the sour notes and mistakes it gobbles? I know, the potential naughty jokes are endless!
