I remember seeing these years ago, but...

Guitar tech has come a long way in the past decade.

I'm amazed that every guitar player doesn't already own one of these.

I do.

My Gibson Les Paul has an auto tune system. Turn on, play a string when the green light comes on play the string again and if the tuning peg does not change, move on to tune the next string.

For some reason I always have the clip on tuner working at the same time or the pedal board in tune mode.
