When I ran sound I used to mic acoustic guitars, front and back if possible, even if they had a piezo. Just gives me more to work with, and if those signals aren’t helpful, I don’t use them. But when you need a little something extra, it’s great to be able to mix in a bit of the thick, dark sound from behind the guitar.
Then I later worked for a band with a guitarist who often used a MIDI guitar, and could send me clean guitar, distorted guitar, and the synthesized instrument. Talk about having something to work with!
Why this isn’t more common, especially for cases like this, I dunno.
