First off, I'm happy. The bass looks and sounds great. Nice finish, transparent red (though wood grain is nothing to see), pickguard is much nicer than the photo. Pickups sound good, though the J pickup is quite weak.
Straight out of the box the setup was OK but needed work (I am an experienced guitar tech). Neck relief was good, nut slots too high, string action was high but easily fixed once the nut work was done. Fret levelling was fine but crowning and polish was poor. Fret ends were very nicely finished though.
Fingerboard wood is poor and I hope they do better in future. Webpage says both "roseacer" and "rosewood". It is *not* rosewood. It's an ugly weird grey-black, like ebony but coarser grained. Mine seemed rough, dry, and brittle. The masking tape I used to protect the board while polishing the frets raised the grain and made it feel rougher. I used micro mesh pads to smooth and then thoroughly oiled it.
As I said, out of the box it was playable and if they were all like that or better at this price I would recommend. With my skills I now have a bass that plays great, but if charging for my time at my standard rates, that would cost 60€ extra.
tl;dr It's playable out of the box, and better than I expected at this price, but can be improved and needs some work to play well.
EDIT: 2 1/2 years on and I regret buying it. It's been in storage for a year and much of the year before that it was just collecting dust and taking up space. Like so many Harley Benton products I've seen (I am pro guitar tech) it can take so much work getting these to play well that you are better off spending more money in the first place. I should have just bought a Squier or Sterling by Music Man.
