These don’t come up too often as they’re no longer in production. It’s a shame as they’re whole heaps of fun! Kala call these a pocket ukuleles – often they’re referred to as sopranino ukes. They’re 11 inches in scale (soprano ukuleles tend to be 13-14 inches) and generally tuned ADF#B – one whole step up from standard tuning. You can experiment with different strings and tunings though.
They’re built with all sold wood (in this case acacia) and with the same care that goes into their larger scale ukes. This one has been lightly used and in good condition. It has a really nice bespoke Kala padded gigbag.
