We produce string instruments all in one key. Focusing our initial release on ukuleles, but soon moving into guitars and other string instruments. Our fret boards are custom cut and custom fretted so that only notes in one key are on the fretboard. Since they are all in one key you never hit a wrong note, everything you play harmonizes. Excellent for mindlessly playing beautiful melodies, or for jamming with friends; everything you play even with other people using our instruments will be in the same key so it will all match. This can also be a very useful as a teaching tool for new players: it can be discouraging after learning the basics and trying to play randomly, as its highly unlikely the notes you play match; it also helps teach scales and gives a great visual explanation of scales as well. Slides become especially unique as they stay in key through the entire slide unlike traditional string instruments.
