Featuring the most popular ukulele body shape, Luna has expanded the Vintage series to add the Vintage Mahogany Concert with preamp. The mahogany body and walnut bridge and fingerboard add sustain and clarity to your tone. Open-style tuners keep the instrument in precise tune, and the Luna UK-T2 preamp with built-in tuner provides easy amplification that can be easily adjusted. This uke sounds as good as it looks. A wonderful instrument for musicians of all levels.
