Beginners or experienced guitarists can take the pain out of tuning guitars with the Roadie Tuner, a small device that will get your strings pitch-perfect in seconds.

Using an app and a small piece of hardware you attach to the tuning pegs, all you have to do is strum the string and watch as the Roadie does the work for you. Even with background noise, it tunes accurately.

You can set up different types of guitars on the app, making it quicker to tune the guitar next time, create your own custom tunings or choose from alternative tunings on the app.

The device is compatible with the iPhone 4S and above, and Android handsets with Bluetooth 4.0. One guitar it won’t do, however, is a bass guitar. http://www.roadietuner.com
