Gibson Robot Electric Guitar

Gibson is about to release a Les Paul guitar that has frequency detecting circuitry in the bridge, motorized tuning machines, and an on board CPU to manage it all. The machines are only slightly bigger than standard mechanical ones.

The guitar tunes itself.

You can select a variety of tunings or program your own. You can also adjust intonation.

Runs about $2200.
