TL;DR:
Pros: feels good, sounds awesome, and is well setup before it gets to you
Cons: Really heavy, and can have quirks if you play in tunings other than E standard without a fret mute.
If you're down here reading reviews, you're wondering if buying this cheap of an instrument is worth it. I decided to bite the bullet so here's my experience. For context I am a recording artist and engineer. Not a lot of live gig use in my case.
I wanted a jazz bass for a while. I've played many, yet never owned one myself. I also wasn't trying to spent over $1,000 on a Fender Jazz. While researching all the different brands, I came across Harley Benton and as humans do, I wrote it off as cheap because well...... this bass is cheap. I always look for sound examples off of YouTube, and I was actually kind of impressed when I heard this guy. I decided this bass was cheap enough, so why not give it a try? After all, it isn't a huge hit against my wallet, and Thomann has a good return policy if I didn't like the bass. After shipping to the US, I paid a grand total of $230 US dollars
Firstly, I was very impressed with the shipping time. I got this bass to my house in the States less than a week after I ordered it. The instrument was well packaged and no scratches/issues with the bass itself.
First impression: This bass feels very nice to play, came shipped only slightly detuned due to international travel, so a quick tune up and I was good to go. Action and intonation were also spot on, so big props to the quality control guys at Thomann. One con I will give this bass, is that it is HEAVY. I weighed it and it is 11.7 lbs (5.3 kg). This isn't an issue for me as I am a recording artist and usually play sitting down, or standing for short periods of time. But this would be something to keep in mind if you are a gigging musician who would be wearing this for well over an hour or longer.
Sound: Trying this out for the first time was a lot of fun. I wanted to get a good sense of what this bass could do so I recorded it two ways. DI, and through my usual recording setup (a Sansamp RBI and an 1176 compressor).
The Direct signal was shockingly good. Considering this is a jazz bass, I'm not all that surprised but still.... I could easily record and mix the dry signal and it would still work well on a record.
But through my recording rig, I was honestly floored. I couldn't get a bad sound out of it. I gave it just a little bit of drive, slightly boosted the midrange, and this thing sounds beautiful.
After my initial testing, I threw on a new set of strings as I planned on using this bass in Eb tuning. Everything still sounded good, but the nut didn't like the thicker strings all that much. The A string started buzzing pretty bad whenever I played the string open. I will say that the bass had NO buzz with the original strings in standard tuning, it just didn't wanna play nice with the new strings. It wasn't a big deal though, I just bought a $5 fret mute off Amazon and the problem was immediately fixed. Just thought I should mention it though. You could fix this by widening the opening on the nut, but I don't really like altering my instruments in a way that I can't undo. Plus the mute was perfectly fine.
Conclusion: For the money, it really doesn't get any better than this. I don't know how the heck Thomann is selling this for this cheap but I'm all for it. If you're on the fence, give this bass a try. Worst case, you're out a couple hundred bucks and you still have a good bass for practice. Best case, your mind will be changed about cheap instruments, just like me :)
