I already owned a Kala acoustic U-Bass with the rubber strings but wanted a solid body for the solid body sound. The acoustic Kala was superb quality so I decided to stick with the brand. I couldn't be happier with this. It is solid, surprisingly weighty (in a good way) and very well built. The paint finish, the fit lines, etc, are all faultless. The metallic candy apple red is lovely and the pickups have a full-bodied sound that is the equal of a Fender Precision but with less boominess (to my ears). The neck is chunkier than many ukulele basses which I like and also means switching between it and my full-sized P-Bass doesn't cause any problems. I also put Kala flatwound strings on it which make it even better (they are lovely, glassy flatwounds although at an extra £80 they are not cheap).
I have tried a Fanner ukulele solid body bass at twice the price which had a nice tone but the build quality was shocking - poor fit lines, shoddy paint, wobbly binding lines and more. I returned it (didn't buy it from Thomann). I also tried a Flight Mini Jazz bass which I also returned (using Thomann's no-quibble 30-day return policy). It had nice paint and was well-finished but the neck was slimmer and rounder than the Kala which I wasn't keen on and the pickups just seemed weaker, lacking in fullness to my ears.
I just wish they came in more imaginative colours. I also own the cream colour (I needed a backup as it's key to my musical endeavours) so maybe it's a good job they don't or I'd have a few more.
You will not be disappointed. Ukulele basses always get curiosity attention from other bass players due to their small size but they are always surprised when they feel the quality, weight/solidity and the hear the tone. It's very clearly a serious instrument.
