Kalium (formerly known as Knuckle) Quake 5-string 39.5" scale (same as 3/4 scale double bass) in pristine condition. Extended scale bass specifically designed for drop tuning (but sounds amazing with standard tuning as well). Features hand-rubbed mahogany body, maple neck with ebony fretboard, 24 frets, neck-through construction, single custom Q-Tuner passive pickup (set up for easy conversion to active), Hipshot tuners and a custom bridge. HUGE, rich, well balanced sound. Beautifully hand crafted by Skip Fantry in Seattle.

As new condition, very light studio-only use, very well taken care of and kept in a non-smoking environment. Includes a custom airplane-safe reinforced hard case and an extra set of six custom Kalium strings for various tuning options.

There are many reviews online praising this beauty. Sound samples: drive.google.com/drive/folders/1dPNV31IBO2bI5_sR1XFNy0vLoJFZtd97?usp=sharing
