What problem is this design solving? A detailed explanation is absent from their WEB site.
Seems like a lot of metal and money for an amorphous promised benefit:
"To be honest with you, the Evertune system was a bit baffling at first. I was skeptical to say the least. What I came to learn during the process of tracking guitars for our upcoming album was mind blowing to say the least. Not only does the Evertune system greatly increase the efficiency whilst in the studio, it allows the player to well, just play"
I mean maybe if you've contemplated giving up the guitar because the intonation wasn't "perfect"? Life is a sloppy mess, deal with it IMHO. I manage to "just play" fine without this and playing efficiency does NOT keep me up at night, but to each their own...
