No experience, and I too seem to recall reading about it before...
But, VERY INTERESTING.
I've got too many guitars to play them all regularly. Also, I've been through a period of not playing everyday for a few months. Now, every guitar I have (even the ones cleaned and new-strung), feels "foreign" and uncooperative. I pick up one for a little blast and put it down again as "not very inspiring"...
For years, I've blamed me and my playing for this effect - and "played through it". My reasoning has been, if you haven't played for a bit, then you are rusty. Equally, if you are "in" on other guitars, but pick one up that you haven't played for a while, then I've always assumed it was me as the player who hadn't "tuned in" to the instrument yet.
This sounds like it might help :D
BUT... I kind of fear we might looking at another "magic bullet" that doesn't actually do too much except trigger a bit of a placebo effect in the player. Still, $150 for a working placebo effect isn't too bad!! :lol:
