The TunerMatic Robotic Guitar Tuner – Is Guitar Tuning Really That Hard?

The TunerMatic is the lastest in the StringMaster line of Robotic guitar tuners

The TunerMatic automatically turns your guitar pegs to tune your guitar. According to the developers, “It is the only guitar tuner that tunes the guitar for you.”

Sounds pretty cool, but the promo video left me thinking – is tuning a guitar that difficult?
