When it comes to ukulele basses, KALA is probably the most famous, but this is a high-end model that Deviser (Asuka) produced in limited quantities about 5 years ago. The original retail price at the time was approximately 160,000 yen. This is a set including the bass body, a dedicated semi-hard case, warranty, and a preamplifier charging adapter. Fully functional, and the preamplifier operation has been confirmed. The strings have been replaced with Worth Strings OP-R. There are two scratches on the headstock and two dents on the body edges. Please check the images for these areas. The body is a rare mango solid top, the neck is mahogany, and the fingerboard is rosewood. The MiSI preamplifier is rechargeable; please check the specifications on the official website or the Deviser page. It can produce a sound reminiscent of an upright bass, and the moderate volume of the acoustic sound allows you to enjoy playing at night without worry. Also, the strings are polyurethane, which lasts longer than rubber strings and doesn't catch on your fingers. It's also a very capable acoustic-electric bass.
