The Lu-21CEK is based on the best selling Concert Ukulele offered by Lanikai with added professional grade Fishman Kula electronics for playing in louder environments featuring an on-board tuner and three band EQ. This handcrafted ukulele is made with Nato wood (otherwise known as Eastern Mahogany) on its top back and sides. When this wood choice is paired with the Rosewood fingerboard it brings out a mellow tone with an enhanced midrange that is often missing in instruments in this price point. The LU-21CEK also comes stocked with die cast tuning machines geared 14/1 for easy tuning. If you have never played ukulele before get ready for a world of fun.
