JU-450 Ukulele: This model comes in a steel string or a nylon string version (JU-400 coming soon). It is based on a baritone ukulele with a 19.2"/487 mm scale length. It is tuned like the four highest strings on a guitar with a capo at the fifth fret (GCea). All the regular ukulele chords work. I will experiment with alternate tunings and report back here.
