Good on paper only
Ikram 05.04.2022
After the purchase the bass was sent were quickly which I appreciated. I got the bass 10 days ago. I went for the top of the line expecting that the quality will follow. On paper this bass has it all but the reality is totally different. Where should I start. First the preamp didn't work so I thought it away. Secondly the pickups are biggggg mismatch the p pickups is overwound I think it was 15 k and the bridge pickup is only 5k so there is no way you can balance this again I thought them away. So I was left with the bear wood and some hardware. The bridge is nice I must say the tuners are solid. The finish is very bad first there is colour mismatch between neck and body since they are both "natural". The wood used is good I must say a bit on a heavy side though. The fretboard was never polished it is straight from the laquer room, the bubbles are trapped under the laquer and for the mos part they are not visible but over the inlay they are very annoying. Frets are very rough you can't play the instrument if you don't polish the frets. I mean if you are not good at DIY don't purchase this bass.


Outstanding value, Terrific bass

*I just got the bass this morning*
That being said I have to say this is a magnificent beast.
Overseas shipping to USA took about 3 weeks once the bass was no longer on back order. Which I was well aware of.
Pros: It arrived undamaged all packaging was in good shape. The guitar had been properly set up. The neck is spot on, It only needed a very minor tuning adjustment to be ready to play. After giving it about 8 hours. to adjust to home temp and humidity. I can't find any flaws or blenishes in the wood or hardware. The electronics are all functioning properly and a wide tone pallette is at your fingertips.
I'll update as time passes.
Cons: If you want to get picky. The body is crafted from 4 unmatched pieces. Mind you they don't look bad and from stage distance you likely wouldn't notice. That is with the natural finish. If that bothers you get one of the other colour options. Weight: it comes in at 9.7 pounds. A few ounces heavier than my Fenders, less than my Peavy T-40 and also less than my Harley Benton JB-75 SB Vintage Series and my Harley Benton MM-84A SB Deluxe Series. But if weight is a issue for you, look elsewhere.
All in all 5 stars for Value, Prefomance, Construction & Playability.
Thomann for making a great producy at such a nice price!!

I'm absolutely not a professional musician, but I've been playing the bass for a few years on a moderate level. I'm also not your tech-savvy guy who knows the ins and outs of magnets or all the fine details of musical instruments; I don't know what the exact advantages of the various materials are, and I have no idea (or even serious interest in) what is hidden behind the scratch board. But I do know that this heavy bass feels like magic under my fingers, has a superb sound to it (with great controls that allow you to adjust it to your own taste), and instantly made me fall in love with playing the bass again. I honestly regret not having bought this wonderful bass any earlier! Warmly recommended to anyone who wants to step up from his entry-level instrument and find out what a real bass feels like.


Amazing bass that gives the Sire basses a run for their money

This is a beautifully made instrument. The neck feels great to play with its satin finish. The body looks awesome and feels very light but the bass doesn't have crazy neck dive or anything. This bass is much lighter than my JB-40 fretless though. The massive bridge and string-through-body design gives it very long sustain. Even the Harley Benton logo has been upgraded on this one. The bass arrived already set up properly, just needed a little intonation work.
The only con about it in my case was the jack plug, which just won't stay put when I tighten it down, keeps untightening itself and getting wobbly - will need replacing. It still works fine though. I really think if you were to upgrade the pickups, it would be competing with basses in the 1000+ eur range.
