This ukulele bass for sale is the only one I kept for myself. I converted it using a Kala long neck concert uke with solid spruce soundboard, K&K Super Double Bass piezo pickups, Hipshot Products ukulele bass tuners, now strung with new Aquila Thunderblack Ukulele Strings, custom fossilized camel bone nut and saddle, solid mahogany neck, unique custom curly koa headstock overlay and comes in a custom made airline approved, tight fitting aluminum travel case. It is in wonderful, like new, condition and is an absolute dream to play, own and hear. The fretless rosewood fingerboard has 14 frets to the body.
