I've just tried a bridge on a guitar I was demoing it's called Evertune it looks complicated inside ,but just as easy to set up as
Any other bridge .But the difference is you can set up the biting point . So as example you can set up the biting point for rhythm
So you can thrash out the strings and it won't go out of tune great for recording, or you can set it up for string bending again won't
go out of tune.The real test was in a video demonstrating a guitar having its 4 strings cut off the guitar while a guy plays and it still
remains in tune . Bit extreme and probably not something that would happen while gigging , but amazing technology

Just read the above and thought. Mmm here's the you tube link it'll explain it so much better
