I have played several Ubasses in the past, and have a Kala Ubass already. This HB Mahagony Ubass is just as good (better in some cases) as any of the other's I've played, and is a fraction of the price. The string action on the HB is the same as on my Kala (I measure 10/64" at the 12th fret of each string), which is a bit high for a bass in general, but is on par with all other acoustic/electric Ubasses I've played (and measured). The HB is very well intonated (12th fret notes are perfectly in tune), which is better than my Kala. The HB pickup/preamp sounds very good (good tone and even volume across all strings and the full register of the instrument), and has a 3 band EQ (better than the Shadow preamp in my Kala). The built in tuner is very good and I really like the "HB" logo that lights up when the note is perfectly in tune, which is very easy to see. The one issue I found is that the rear access door is nearly impossible to remove (6 screws which is more annoying than the magnet that Kala uses, and then the door is on so tight that I feel that I need to break it to remove it ). Overall, this HB ubass is an incredible value and the quality is just as good as Kala.
