Concert ukulele from Luna. In the most popular ukulele body shape, Luna expanded the Vintage Series to add the Vintage Mahogany Concert with a Preamp. The mahogany body, and walnut bridge and fretboard add sustain and clarity to your tone. The open-style tuners keep the instrument in precise tuning and the onboard Luna UK-T2 preamp with onboard tuner provides easy amplification that can be dialed in quickly. This uke sounds as great as it looks. A wonderful instrument for players of all skill levels.
