has anyone heard of this had it done etc. they do mandolin's guitar's and fiddles. It's $600.00 to have done but they have a volume increase of 3-6db and do all kinds of test. the guy who came up with it has been on the cover of wired magazine and is some kind of super genius. here is a interview with him. seems like a cool concept. http://alchemyacousticlabs.com/the-p...h-frank-sanns/
