I don't see ukulele topics very often on HN, thanks for posting!<p>I'm a uke player and I have an "octave ukulele" too. If anyone is curious to try this out themselves, here's a link to the strings I use on mine (they're called Perry's Octave Ukulele Strings). You just put them on a baritone uke and tune them to (low)GCEA. They are great strings: <a href="https://starlightukes.com/product/776499" rel="nofollow">https://starlightukes.com/product/776499</a><p>I must admit, I don't think the octave ukulele sounds that much like a cello, but I see you only said it sounds a "little" like a cello, and I get what you mean with it being a deeper sound :).
It sounds nice, and I like it more than a regular ukulele. But I remain unconvinced: I still haven't heard anything at beautiful or mesmerizing at the sound of Cello.
