The Kala MK-B Baritone Ukulele is crafted of Agathis - a wood that is similar in appearance and tonal properties to mahogany, along with a rosewood bridge. The MK-B pumps out a lot of sound, and delivers a warm tone. The mahogany neck features a rosewood fingerboard with 18 brass frets. Guitar players will find the transition easy to the baritone ukulele because of the D-G-B-E tuning, low to high, and they will love the low action and ease of playability.
