Harley Benton JB-75FL SB Vintage Series

As seems to be the case - HB products really set bar high for other inexpensive musical products!
My initial idea was to buy a cheap bass and then maybe change the bridge, pickups and tuners just to polish it up a bit. Well, bridge and tuners are doing their job quite well so there isn't any critical reason to change them (as they don't arguably affect the tone as much as the rest of the parts anyway...). What about the pickups? They're staying! This bass has a really nice warm and balanced tone when both pickups are full (a bit of woolliness can be heard, though). Rolling the neck pickup back a hair opens the sound really nicely and harmonics ring pretty loud and clear. Soloing the bridge pickup does exactly what it should do. Sound is clear, melodic and harmonics loud and bright - without being harsh! Some electrical hiss is present when pickups are not in equal positions but that is kind of expected in any passive j-bass with single coil pickups.
So ultimately I ended up just changing the strings to D'Addario Chromes just to save the fingerboard and thats it!
Construction is in all respects on par with more expensive basses (not boutique of course...). At least on my bass the pau ferro fingerboard is a beautiful slab of wood, the maple neck has some really cool grain patterns on it and lastly the three piece ash body is very well joined and matched. Finishing is really good all around and the sunburst is pretty much flawless. Pickguard is cheap -ish, but by no means bad looking (I'm keeping it on place).
I don't really know what more one would get in terms of overall quality by spending double or even five times the money spent on this bass. Parts with more established names probably?
For those who care: I have about 30 years of experience playing high end and low end basses just to point out that although these are just my humble opinions they are not done without any knowledge of other basses, parts, pickups or electronics.
All in all an excellent buy and really good basic fretless bass!
*Edit after one year of playing:
So first things first - I still love this bass and keep playing it daily amidst my other basses.
Some fixing and modding has happened though. I ended up changing the pickups after a year to EMG J's with tried and true Vol, Vol, Tone -electronics. Woolliness of both pickups full has vanished and sound is more open. It wasn't all that bad to begin with, but definitely an upgrade worth doing. No electric hum anymore either when soloing the bridge pickup!
Finland is quite a hard climate for wooden instruments because of the changes in humidity during different seasons. After the first winter I went on to sand and polish the whole fretboard and applied new oil to it. Trimmed also a few fretmarker ends that had started sticking out on the treble side of the fingerboard. Now it's perfect and also keeps in tune amazingly well. And yes, still love this bass :)

What a perfect instrument. Just a little heavy. It looks good, and the pickups are great. Not to mention the roundwound strings. Absolute dead-on fit for the tone of Jeff Ament. It feels great to play as well, and it's very fun to play. I'm addicted. It'll bite your fingers a while though, so the first few days will be tough because you have to play but it hurts. This bass actually made me learn to use my pinky which isn't that hard actually, and my pinky is very weak. It's different than what I'm used to, you generally need it here to stay in tune and because of the long scale. Had no problem migrating fron short-scale fretted. I didn't find this instrument to be hard to play at all, so don't be afraid.

Sorry for the wall of text, I don't know where to split the paragraphs at this time of day (3:30 am).

But great quality instrument, Harley Benton basses seem great from my experiences so far.

You will love it! I sure do.

Decided to give a fretless a try for the first time and have read generally positive reviews about Harley Benton so thought it made perfect sense to give one a try.

Everything about the purchasing experience was excellent. Thomann does it right. Excellent communication and I received the bass 3 days after purchasing it. The bass was packed extremely well. Double boxed, plenty of foam packing, the fingerboard was protected, the pickguard, chrome cover-plate and pick-ups were also protected. I was genuinely surprised how well it was packed.

The action was very low out of the box and I've kept it that way. Had to do some minor saddle adjustments to get the intonation right and the bridge is definitely a place where an upgrade would probably be worth it. Its not terrible but the saddles are a little sticky . But I was able to get spot-on intonation without having to adjust the truss rod so a bridge upgrade isn't a priority for me.

Playing a fretless for the first time was pretty awesome. Should have picked one up sooner. Took a little getting used to but in a cool way as I immediately started liking how easily I could manipulate pitch with my left-hand. The pick-ups on the Harley Benton are pretty lively, seem a bit hotter than my Geddy jazz stock pick-ups. Pick-up volume and tone pots are all smooth and responsive. Love the overall sound of the bass and the neck is smooth and easy to play.

The bass is heavy (mine is about 12 pounds) so a wide, padded strap is helpful. It plays unbelievably well given this price point.

Bottom line, the Harley Benton impressed me completely. Extreme bang for the buck. Its almost hard to believe how good this instrument is for this price. This was also my first purchase with Thomann and I'm completely satisfied with the purchasing experience. So satisfied in fact, that I just ordered another bass.

Really enjoying this guitar. The neck feels wonderful and mine has a lovely flamed maple back that I really wasn't expecting. Bought as a mod project and will probably swap out the pickguard, which does feel cheap, but there's really not much room for improvement otherwise. The pickups are better than I expected, but could easily be upgraded. Gears feel basic, but it holds tune fine. Truss rod needed a tweak because the neck was too straight and the fingerboard needs a bit of oil to darken and and moisturise it. Fit and finish is perfect though. If you want an inexpensive fretless bass, this is a great pick. Going to have to seriously consider buying more HB guitars...
