Moog Guitar Video
A whole band in a guitar
(Thanks to Canon for providing the FS11 camcorder for this video.)
The demo was ok but you must mic the talent.
If you're worried about mic rustle then use double sticky sided tape. G tape works well, too. This sounds as though it was recorded with a standard issue camera mic.
Come on guys it's location audio 101.
Raise the level and clarity of his voice with a close mic, wired or wireless, and while you're at it mic the amp so you get a better sense of the sound of the instrument. This highlights the sound of the room at least as much as the guitar and amp. Highlighting a musical instrument with sucky audio is ridiculous.
