Having entered the world of stringed instruments about a decade ago with a line of guitars designed specifically with female players in mind, Luna Guitars is the brainchild of musician and stained-glass artist Yvonne de Villiers. Luna has grown and now makes a full line of instruments, including a large array of ukuleles joining the company’s acoustic and electric guitars and basses. Having been impressed by the sound, feel, and value of Luna’s acoustic guitars in the past, I was happy to check out the Mo’o Cedar ukulele—a concert- size instrument with a solid cedar top and a built-in pickup.
