Do you want to buy a Kala U-Bass?
I want to help you find the U-Bass that suits you. I’ll try to make it easy for you to understand all the differences between the models. I will focus only on the electro-acoustic models and not on the solid-body models.
The Kala U-Bass is probably one of the coolest instruments ever made.
Following this invention by KALA, other makers tried to imitate this instrument, and a whole new kind of musical instrument was created. Many bassists, included me, became addicted to playing it.
My Experience With The Kala U-Bass
The first time that I’ve played a U-BASS was in 2010. I sat down in a music store to play that thing and could not stop. I did not believe what I was hearing – the quality of the low frequencies coming out of this tiny gadget was superb.
It felt like playing a musical instrument that looked like a toy but sounded like a double bass when connected to an amplifier.
And that’s before I mentioned the strange strings on this instrument, which takes a few minutes to get used to, but once you do get used to it, it’s hard to stop.
That day I certainly enjoyed playing, but I was also skeptical. The price was around
400$ (that was the basic model and perhaps the second that Kala made – there were not as many options as today), and that’s not what I intended to spend, certainly not on such a small instrument that looked mostly like a gimmick at the time. so I didn’t buy it.
But – after that day and for a few weeks, I was sorry that I had not bought the Kala U-bass. I thought that such an instrument could become a substitute for playing double bass at different shows and in fact,
the 400$ price tag was not too much to spend for this goal.
After I finally got the U-Bass, I started to use it on various gigs and recordings.
The first thing that happened, since no one at the time knew what it was, is that I became the center of every show. Members of the band and also the audience was impressed by the sound and size (or lack of size to be exact) equally.
Slowly I began to understand better what would be a good use for the U-bass and what’s not.
Over time, I even upgraded to several newer models of the Kala U-Bass and I will review them here as well.

Here is my Kala U-Bass Review:
The original “U-Bass 2”, which I had, had a lot of flaws and it is now unavailable for purchase, but luckily Kala has made a lot of progress since then. They added a preamp, Volume and Tone knobs, and a built-in tuner on all models.
The tuner is very much needed because I couldn’t find any tuner that can tune the U-Bass properly apart from its built-in tuner.
The other thing that has improved is the quality of precision and intonation of the fretting.
With the old models, even if you have tuned the bass in the right way, still some notes always seemed out of tune.
Well, these days are over, much due to the truss rod, which Kala added to all models.
So what is the difference between the models?
There are a few points to note when choosing between models:
The basic and original strings of the U-Bass are the Road Toad Pahoehoe. These are the original black strings. They are made of a material called polyurethane, which is used for making sponges, car tires and even skateboard wheels.
The feeling of playing them is quite strange – It’s something between rubber and plastic. Playing these strings adds to the general feeling that you’re playing on a toy instrument, but as noted above, the low frequencies that come out of the bass make it clear that this is far from being a toy.
You can find these strings on most models of the U-bass but not on the low-priced models. Their production costs may be higher.
These are low tension strings, which are easy to play, but they are also quieter and require tuning more frequently.
Buy the Road Toad Strings on Amazon.com:

The next set of strings are the Aquila Silver Rumblers. These strings come with the rumbler model, which until recently was the most basic model among all the U-basses.
These strings have higher tension and therefore more accurate for playing, don’t get out of tune that much and giving a louder sound. At the same time, they are a bit more challenging to play and a little less adaptable than the Road Toad’s because they are less smooth and thicker. Also, there is a difference in feeling between the two high strings and the lower two strings – it is easier to play on the high strings.

Another option for strings is the Kala Round Wounds.
These strings can be found on the Exotic Mahogany, Striped Ebony and Journeyman models.
These are the middle price models of the Kala U-Bass.
They are made of metal cords. Because of this, they have the highest tension of all U-Bass strings, which helps to get a stronger and more precise sound, with accurate tuning.
This way, you can get a musical instrument that sounds just like any other acoustic bass guitar, but almost half the size.

The last option is the Aquila Thundergut strings.
These are the white strings that you may have seen on some of the other Bass Ukulele makers models. Starting in 2018, Kala also adopts these strings in the newest and most affordable models they have ever produced.
These strings are very similar to the rumbler strings when it comes to tension and precision, but they emphasize the higher frequencies while trying to match the black Pahoehoe.
In my opinion, there is a little improvement from those black strings and also from the RUMBLERS, especially with touch and tension, but I prefer the lower bassy sound, so there is no perfect solution.

Other elements that vary between models:
Tuning keys –
There are two options:
The simple model is the Custom black die-cast,
Which you’ll find on the Rumbler, Solid spruce top and the series of new affordable models – Wanderer, Passenger, Journeyman. I think you’ve understood who’s going to use them 🙂
The second model is the Custom Hipshot Ultralite, which is found on all other models.
From my experience, the Custom Hipshot Ultralite keys give value for their price.
The simple model is not as good with tuning and wears out easily, at least from my experience with them.
Nut / Saddle –
Unlike the early models where the saddle and the nut were made of plastic, Kala installed a Graphtech nut to the new models.
This is a significant improvement, and the strings sit better on the fretboard.
With the three newer and affordable models, they’ve gone back to plastic.
Back access – Here, too, in those affordable models, Kala has gone back to the old solution of screwing the cover. All other models have a cover with magnets attached to the bass’ body.
You don’t need to worry about the screws; it’s just less fun.
Summary – Which model should you buy?
It depends, of course, on your budget, your needs, and the level of your playing.
So let’s go over all the models (2019) –
Mahogany – Wanderer / Passenger / Journeyman –
These are the most affordable models ever created by Kala.
These models are recommended for beginners, who want to get a U-Bass, or for musicians who wish to play their bass on their couch, in front of the computer or on vacation. This will be perfect for fun or practice, in places where the full-scale bass is less comfortable to use.
Notice that the Journeyman is the only Kala Acoustic-Electric U-Bass that has a cutaway. There’s also a Journeyman model (Black/Red) that comes with Round Wounds strings on it.

Kala Journeyman Black/Red (Round Wounds) – https://amzn.to/2NrUCb4
This is the middle range model of the Kala U-Bass.
Pros: Price, strings (for the people who like the Rumblers strings).
Also, The Fretless Rumbler is the most affordable Kala U-bass fretless.
Cons: Tuning keys, strings (for other people).
Who should buy it:
Those who have been playing for several years and want to add this bass to their guitar arsenal for rehearsals and performances purposes.

Exotic Mahogany or Stripped Ebony –
In my opinion, these are the best models in terms of cost-effectiveness.
These models have all the well-made parts, and they come with the classic black Pahoehoe strings. Although these strings have their drawbacks, in the end, This is the Kala U-bass’ Original Sound.
Who should buy it :
Anyone who has the right budget, and professional musicians who need the “acoustic” sound for their performances. Double-Bass players who do not want to carry the Double-Bass to every rehearsal/gig.
You can also buy the model that comes with Round Wounds for an “electric” and stronger sound.

Spruce Top (Mahogany sides & back)
If you can tell the difference in sound between this model and the previous one, you may want to pay more.
If you can’t, I’m not sure you should.
You should also know that this model comes with the Custom black die-cast tuning keys, which is not as good in quality as the Custom Hipshot Ultralite.

Solid Mahogany –
The most expensive and high-quality model.
It is made of solid wood. Both nut and saddle are made of wood, and it comes with a hard case.
Who should buy it :
The Kala U-Bass Fanatics, and those who need the hard case.
In terms of sound and usefulness, I did not find a big difference between this model and the Exotic / Stripped models.
Maybe you’re one of those who wants to feel that they’ve bought the best.
And that’s perfectly all right.

How to record the U-Bass?
If you are a professional musician, music producer, or if you want to record the U-Bass at home,
Here are some tips for recording:
Like all acoustic instruments, the U-Bass requires some experiments to get a good recording sound.
And like any acoustic instrument, the U-Bass should not (preferably) connect directly to the console/preamp/sound card.
The direct connection doesn’t give the full sound, and it may sound poor.
With the U-Bass, like any acoustic bass, the problem is more severe because of the annoying ticking sound that comes with recording it. If you play live concerts, you may not feel it, but in a home studio or a professional studio, you definitely would.
The solution is, of course, recording using microphones.
For professional studio owners, my recommendation is to plug the bass into a bass amp at a separate room. Then use two microphones: one to record the amplifier and the other to record the bass.
If your studio does not have two rooms, I suggest you try one of the two: Record a bass amplifier with a microphone, or record the bass with a microphone, and check which sounds best for your project
If all of these options are not available to you, I recommend that you double your direct signal with an electric bass track or a midi bass track. This will give you the full sound that you need. Good Luck!

Hello! thank you for this review.
Do you know how does the ubass sounds on an electro-acoustic guitar amp? For instance on a Yamaha THR10 ?
I don’t know about this specific amp,
but I have tried it on some vintage small guitar amps (not tube),
and it was very cool. Just be careful with high volumes/high gain – it may ruin your speaker.
I’m actually a uke player, but have always wanted to get a bass to play around with… and generally see what it’s like to play bass. When I saw the Kala U-bass range I thought ‘I’m gunna get one of these. Not being a bass player, it’s a bit hard to know where to start. This review is probably one of the best I’ve seen, thanks.
I like the look of the journeyman, and it’s price. The red one is the most appealing to my eye!!
The red Journeyman seems to come with metal wound strings. Does that mean that I have to use those strings on that bass, or will it accommodate any of the other various string types. Because I’m sure that over time I’d want to experiment with the various string types.
Thanks for writing. I’m glad I could help with this post.
I’ve actually bought a Journeyman red U-Bass lately.
I’m going to write a review about it soon.
I find the metal wound strings the best because they are the loudest, and they have the highest tension, so there are no intonation problems.
This is not the “classic” U-Bass sound, and of course, you can re-string the bass at any time with any U-bass strings set.
Also, I like the cutaway.
As always, if you’d like to use my affiliate links, that would be very appreciated.
Thanks for the reply Idogo. I too went ahead and bought the red journeyman. I bought it online, but as I work out in the bush (fly in fly out), Ive had it delivered to my home, so went get my hands on it til mid January…. really looking forward to it. I also have purchased a set of vox bass headphones to keep me going until I buy a bass amp.
Hope you are enjoying your red journeyman, it’s a pretty sexy looking instrument!!
Hi I noticed a secondhand Rumbler for sale in immaculate condition at about half retail price . I’m a professional musician and love the sound of the U bass. I’ve seen a friend of mine playing one @ gigs and on TV and loved the sound for what it is though I wasn’t sure of which model he was playing. I was just wondering do you think the rumbler series would be adequate for recording as I play in an original band but also pick up session work as well or should I be looking at a higher model? Would the sound be that different in the studio through an amp as described by you for recording between the Rumbler series and the mahogany or spruce models? Just wondering if it would justify spending over twice as much to buy one of the higher end models new? I look forward to your response cheers Rick
Hi Rick. Thanks for your comment.
I don’t think there is a big difference in sound between the models.
What makes the difference in sound is your choice of strings.
As a matter of fact, after playing on most models, I now own a Journeyman Red U-bass (the most affordable U-bass With Round wounds) and loving it.
The Rumbler model has its own set of strings (The grey thicker strings), and these have a very distinctive sound.
I suggest that you ask your friend about the type of strings he plays or just listen to some demos of different types of strings,
this way, you can buy whichever model you want and replace the strings if needed.
Please note that the rumbler strings are thicker than the other sets, so not all models would be suitable for them.
Which fretless would you recommend ? Thanks
Right now I’m hyped about the Journeyman for all purposes. I prefer rounds strings.
