Playing the guitar is a lot of fun. Learning to play the guitar isn’t always that much fun. Many bright-eyed students give it up after a few weeks or a few minutes because the learning curve can be steep. Incident Tech is trying to solve that problem with a whole new approach to learning. The gTar is a fully digital learning guitar for iPhone owners. Simply dock your phone into the body of the guitar, load the app, and watch as the various frets light up, showing you what notes to play. Three difficulty settings let you progress from strumming open strings only to playing every note of the song. New songs are being added to the app weekly, so the library should just keep expanding. You aren’t going to write the next Stairway to Heaven on this thing but at least you can learn to play that amazing solo. The gTar is on Kickstarter now.
