When we had a thread on this awhile back I related that in Acoustic Guitar Magazine someone had tested a device that was a "Guitar Shaker." The guitar was mounted in it and literally shaken at some frequency or another. Same idea that y'all are talking about. But like JP said, playing the thing is still the key and if it doesn't sound good in a year or so, it ain't gonna'! Much is made over the aging process, but you can tell within a year whether a guitar is going to really "grow."
