Mark Leue has been a luthier for over 40 years. Although he specializes in Upright bass and has over 30 basses for sale at any time, he has experience in practically any instrument with strings. From his beginnings as a teenage guitar maker, later a violin maker, and all along a luthier to all stringed instruments, you are in good hands when buying an instrument or looking for a professional repair to a beloved friend or a family heirloom. Violins, violas, mandolins, banjos, guitars, cellos, and of course, basses. If it has strings, he can repair it.
