Indeed, it was the Fireproof Babies that planted that particular seed of desire.
Much like I associate your use of the otamatone with my wanting, and eventually getting, one of those.
And the next thing on my ‘I kinda want one of those’ list is a Ubass, which I was also first made aware of by you.

How fun that we’re drawn to similar instruments! The Ubass is a blast. I love how it sounds similar to an upright bass. These days, there are some other brands that make a bass ukulele that are more affordable than the Kala Ubass.
