The MUB70S is a baritone version of Mitchell s popular MU70 ukulele and features a rosewood back and sides. An upgrade to a solid spruce top provides increased volume and sustain and its abalone rosette and purfling add a classic touch. The special D-G-B-E tuning—same as the top four strings on a regular guitar—allow players transitioning from guitar to uke to feel right at home. A case is sold separately.
