Seeing the guitar tuner thread but being a non strings player got me to re-visit an old idea. Seeing as we now have all the micro technology required why doesn't someone come up with an on-board 'auto-tuner'.

Sort of thing that would sit on the head and connect to tuning pegs, auto detect the string frequency and the use micro servos to keep the strings in tune? Want to use open tunings? Fine - quick re-prog. Want to play 'out of tune' (eg to fit with off key instrument) - Fine, switch it off!

Any guitarist out there want to make a fortune out of the idea? - Buy me a pint (or three) from the profits.

Any good reasons it wouldn't work?
