I got a tip from Oreck about a "cool little gadget that automatically tunes my guitar perfectly" using his words. It's called the String Master.

Basically, it's a Robotic Guitar Tuner. While in their site it says "World's First
Robotic Guitar Tuner" I have my doubts because I've seen friends using similar devices, but maybe they're right, who knows? The difference could be that this one uses "advanced microprocessor technology" like no others use.

The feature I haven't seen in other Guitar Tuners which the String Master has, is the following: "...the only guitar tuner that can re-string your guitar; automatically unwinding the old string and winding the new string with a push of a button." Pretty cool, meaning no work...just sit and watch the magic!

Video Demo Available at hotguitarist.com, with more information too.

It costs $49.95 and works works "on any six string electric or acoustic guitar
with an output for a guitar cord", except the acoustic guitars without the built in pick-ups. You need an adapter for those, price: $12.95
