Moog Guitar 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.
