I had a lot of fun like that at clinics, Don...I'd intentionally play the acoustic guitar out of tune, and then abruptly stop the song, admonish the guitar player, and then "tune" it using the pitch wheel and some well chosen notes. It always got a laugh.

The arranger is quite a palette of sounds and a great source of ideas.
