Tronical TunetronicalA $329 gadget called the “TronicalTune” won the “Best of What’s New” award from Popular Science magazine. It attaches to an electrical guitar and tunes it for you. We mean literally.

The device turns the tuning keys on the guitar’s neck as you play. You can even set the instructions to turn some or all of the strings slightly off-key for special effects. There’s a YouTube video showing it tuning a guitar for special effects even in mid-performance.

The TronicalTune tunes a guitar within seconds. The device weighs about eight ounces.
