This instrument is excellent. The tones from the pickups respond in the way you'd expect from their 'jazz' configuration and all the 'Jaco' to 'Marcus', sounds are very well-represented. The build quality is of a very high standard, frets dressed nicely. If I have a criticism, it is that the nut wasn't smoothed off but worked as it should. I'm being picky; something that I sorted out myself within minutes.
The hardware is cheaper but functional; tuners holding pitch fine. The bridge is fine with 'brass' saddles. The bass wasn't quite 'in-tune' but again, once I had adjusted the bridge, no problem. The neck has a kind of 'D' profile, so don't expect the 'modern' jazz here - it is a 'vintage' model. However, I love the dimensions and the neck itself is very comfortable and solid. There is probably a finish on the back of the neck but essentially it's 'unfinished', meaning that it's very easy to get around. This is a very playable bass!
If there's a drawback certainly for me, it's the weight. The body is a three piece ash (American?) and is too heavy for my (older) frame and that's why, most reluctantly, I am returning this truly fabulous instrument. This has been a hard decision and I would encourage HB to come out with a lighter body version as at this price point, aimed at the beginner - they would benefit from an instrument that doesn't weigh them down (me too!).
I have been a professional bass player for many, many years and I was looking for a cheap bass as a project to play around with, perhaps replacing the hardware and experimenting with different pickups - obviously, I wouldn't be playing around with one of my vintage basses.
In conclusion, I would recommend this instrument with confidence. Don't be put off by the name or the crazy low price. This instrument represents a 'bargain'; the weight just didn't suit me. I would happily play this on a gig - I'm not a 'label' snob and I would challenge anyone to tell the difference between this and say a Mexican Fender at four times the price? However, it's all subjective but I would suggest that if you're looking for a 'vintage-style' jazz, this has got to be on your list.
