Google scares the SHIT out of me. This popped up from their news service at the bottom for me.
Invention Awards: A Bridge That Keeps Guitars Always in Tune | Popular Science
"Guitar strings need constant tension to stay tuned, but they’re easily loosened or tightened if the temperature changes, the instrument gets knocked around, or the guitarist just plays too hard. In an EverTune-equipped guitar, the bridge, which holds the strings in place, contains six spring-and-lever contraptions, one at the end of each string. These keep the strings’ tension constant even if the tuning pegs get turned or the strings become loosened or tightened accidentally."
Looking at that diagram...what's the difference between that and a tremolo bridge, other than the fact that each string gets its own spring?
I guess what I'm saying is: that won't work
After watching the demo video:
Every time the saddle moves, the action and intonation will be wrong. Plus you can't bend notes except in certain settings?
