The VB702GR Wilhelm Klier Gamba Series Professional double bass outfit is crafted with German tonewoods in a 19th-century traditional workshop style. This master series bass features a Gamba design crafted with much older seasoned tonewoods to give the bass a warmer sound and a hand-applied varnish for visual enhancement. This multi-layer spirit varnish enhances the appearance to create a deep coloration for an exciting, antiqued look. Tonal adjustments to the top, back and bass bar only fortify the rich sound and resonance of this instrument, making it an excellent upgrade for the advanced musician.
