Affordable classic

The Harley Benton JB-20 LH is a four-string "J-style" bass that is especially interesting for left-handed bassists who prefer the look and sound of a classic, but don't want to spend a fortune on it. In terms of design and features, the JB-20 is based on the well-known American model from the 60s and already offers amazing sonic flexibility with two pickups and passive electronics. A simple bass with no battery and no limitations at a price that won't break the bank.

Reduced to the limit

A poplar body, a maple neck, and an amaranth fingerboard are the basis of the Harley Benton JB-20. Just like the original, it has a bolt-on neck design, which ensures a sound with plenty of attack. 20 frets offer enough space for basslines of all kinds and the neck itself, which is 38mm wide at the nut and features a C profile, promises an instantly familiar, comfortable playing feel. Two pickups and passive electronics with a volume control for each pickup and a master tone control have always been part of the "JB" signature sound, and the JB-20 is no exception. That's all it takes to make musical history, but it's not only the sound that counts: So do the instrument's looks. The JB-20's design, finish, vintage-style machine heads, and pickguard all contribute to its authentic appearance, and the Three-Tone Sunburst finish gives it a modern yet understated appearence.

Great sound at an affordable price

The Harley Benton JB-20 is clearly aimed at musicians who are price-conscious but still want to get their hands on the look, feel, and sound of a classic. Stylistically, the JB-20 cannot be squeezed into just one category. In terms of sound, it is at home everywhere - from Pop, Rock, Funk, and Soul to R&B and Jazz - thanks to its two pickups. Beginners looking to find out whether playing the bass is something they enjoy will be particularly pleased with the low price, as will musicians who would like to acquire a decent bass as a second instrument.

Surprising great bass guitar
Happy D 29.12.2019
I mainly sing and play acoustic guitar but always fancied having a go with bass and play at my local jam nights. Didn’t want to spend a lot of money just in case it didn’t work out so I went for the cheaper HB bass.

Got to say I am super pleased with the bass. It’s really, really nice! It looks great and plays remarkably well. Sounds great through the amp so I am very happy. It did need a little truss rod adjustment and a small set up out of the box, but hey so did my £700 Taylor acoustic when it was new! Half a turn on the truss rod and oil on the neck and we were good to go.

If you are thinking of buying a lefty bass don’t even hesitate it’s great! I think I will have the P bass next :)


SLAP the LIKE button if you're a lefty bassist

A fantastic budget bass for someone like me, a left-handed guitarist who wanted to pick up a bass to SLAPP when the feeling strikes.

I can't imagine being able to pick up a legitimate musical instrument for less than this price. Like any guitar off the shelf, it needed a setup. But I am into that sort of thing and was able to get this bass to play the way I needed it to play in around 10 minutes after fixing the following:

High action at the first fret. Sanded the nut down a tiny bit.
Found three high frets. Leveled them.
Followed this with a typical setup of desired action and relief; set the intonation. It plays and sounds great!

The pickups aren't amazing, but again, this is a $93 bass. I would never have thought I could have purchased an instrument of this quality for less than $100. If you are a tinkerer and know basic guitar setup concepts, you'll have no problem setting this up the way you like it. If you aren't picky, then you'll probably have an even better time.

There's no way I could have gotten something like this, as a lefty, at this price. I wouldn't hesitate at all to recommend this to my fellow southpaw SLAPPERS.


Another result from Harley Benton!

I'd been contemplating picking up a bass for a while, but left handed options are limited, especially at the budget price end. Having already purchased a stunning CST-24 I knew they could put out a quality instrument, so I took a gamble on this JB-20 ... and I haven?t been disappointed.

There?s one tiny flaw on the instrument in that the neck is not properly aligned, with the G string much closer to the edge of the fretboard than the E. However, whilst its visible it doesn?t affect playability at all.

Other than that, the bass is solidly put together, holds tuning well, and sounds (to my ignorant ears!) pretty damn good. The finish is flawless on my example and everything hold together very well.

In all, a crazy amount of instrument for a crazy price!

I started playing bass around last year and found it incredibly difficult to find a bass that was not only left handed but also affordable in case I decided I didn't really want it, and the JB-20 is the perfect fit for that. It's affordable, it's rather comfortable to wear with a strap and it's got a great sound to it, however it is a budget bass, so don't expect it to be a lifelong purchase. The bottom pickups are not completely aligned to the strings, you can see little gaps in the body where the shape was cut out and (with my model at least) the A string buzzes because the bridge is slightly loose, but then again it is just a starting bass. Overall I feel like it was a good buy and you should consider yourself if you want a decent sounding Jazz bass
