Now when are they going to do the same thing for guitars, mandolins and banj.... no never mind the banjoes. Nobody I know has managed to tune one of them properly for two tunes in a row, so why start now.

How about a system of strain gauges, one on each string, settable by the player to suit the note wanted, and connected to a miniature motor on the machine head. Simply set the note wanted for the open string, press the button and hey presto.... buzzzzzzz, whirrrrr, twanggggggggg. Perfectly adjusted and ready to play. Might need the transformer out of JohninKansas' arc welder to run the thing, but think of the revolutionary new steps in getting money out of string players' wallets.
