If you are a novice guitarist, the biggest challenge you have apart from finding the right notes & chords is to get the instrument tuned properly. A lot of dabbling musicians find it difficult to tune their guitars. Say hello to Roadie Tuner - a tiny & portable guitar tuner that does the job for you - right from tightening the strings to knowing whether you've got the perfect tuning.

All you've to do is connect the output of your guitar to your mobile phone (for acoustic, you may rely on your phone's inbuilt microphones) and select the type of tuning you want. The app provides you with the presets so you don't have to remember different types of tunings.

The Roadie Tuner will measure the frequencies and tighten or loosen the strings accordingly to give you the perfect tuning.
