If you're jamming with people, you at least want metal strings to project some. If not, any U-Bass should do fine.

Thank you. I had no idea, and have never heard it properly pronounced.

[@kenstephanie8445]

Thunder reds are high-tech. Formerly the only way to make a string deeper was to increase the diameter but these strings have in increased density by adding copper to the formula. They have a much more full sound, and are not sticky so they have less finger noise.

[@stephencoxbass]

I'll have to try them out sometime soon!

[@richardletaw4068]

@kenstephanie8445, the three factors in string pitch are diameter, mass, and tension. Change any of those and you change the pitch. Change any two or all three, and that math you said you’d never use after high school comes into play!

[@AllbeeHivezChristianAllbee]

I definitely liked the sound of the flats best. If I ever get a U-Bass (or any copy thereof), flats will be going on it.

[@kentrussell4007]

I have the rubber strings on my Ubass and I solved the "sticky" problem with String Fuel from Music Nomad. I like it better than Finger Ease because you don't spray it on the strings. I can slide without detuning the note.

Awesome! I'll have to look into that. Thank you for sharing!

[@Tanglangfa]

I’ll check it out. The stickiness is the one thing I don’t like about my ubass.

String Fuel is awesome for any regular guitar or bass strings as well. If you use it regularly and wipe the strings they last about 3 times as long.

[@andyswain9407]

Think I'll still use my rubber strings, as they give the natural bass sound. If the price were lower, I might have tried the flatwound, to give a bit more of an electric bass sound, with less scratchiness than the round strings.

[@stephencoxbass]

Price does play a big part. Flatwound and rubber are my two favorites. I seldom use the round wounds these days.

Many thanks for the comparison. It's really helped me decide to stick (no pun intended) with the polyurethane strings originally fitted to my Laka ukulele bass, as they really are best for the upright bass tone I bought it for.

[@jellyfishinterrupted8085]

Reality check: I have the red kala ubass with round wounds. If you already play a normal bass, in NO way are you going to 'rip your skin' with round wounds. The feel is in no way more rough than normal round wound bass strings. The round wounds are absolutely amazing. The sound is kinda like a hybrid between a very good Precision bass and a double bass

[@stephencoxbass]

I was speaking from experience. Sliding a lot on the E string in particular is a bit more effort on that slightly larger gauge string. Think of it like sliding on the B string on a five string a bunch. There also seemed to be something about the silver plating that may have caused more friction. I'm glad that you didn't have that experience, but this might be different for different people.

[@frien_d]

I removed roundwounds from every actual bass I have and went for flatwounds, but now I'll be putting them on my rubber-stringed ubass. Because I crave that volume.

[@narcolept14]

I saw someone asked about "is it possible to change from Roundwound to Rubber Strings" then I have the same question, so I asked Kala's support, their answer is - "The only issue would be the size of the nut and the holes in the bridge. The rubber strings are larger and may need both the nut widened and the bridge holes drilled out. The neck can handle the tension of either but it may need truss rod adjustments." So I am just posting here and I hope this information is useful :)

[@stephencoxbass]

It's very accurate info :) I haven't had to widen the holes on any of mine, but the grooves in the nut did need to be widened for the flat wounds. Thanks for watching!

[@sailorelgee]

Thanks! I came searching the comments for info about this because I ordered rubber strings and the luthier said he couldn’t fit them… which had me perplexed as to why Kala would sell strings that didn’t fit.

[@vickielawson3114]

Put the flatwound strings on the one with the pretty figured wood, and you have the perfect one.

[@stephencoxbass]

I’m sure that would have a good tone. For now I’m keeping the round wounds on that one, but maybe one day… Thanks for watching!

[@OttosTheName]

During normal playing where I never really slide up more than 2 semitones I've never really noticed the intonation/sliding problem on Rubber strings. I'm using the ThunderGuts btw on a Harley Benton, I don't know if the 21" scale makes much of a difference (longer scale = more tension, so in theory it could help). If I get sweaty hands the strings do get hella sticky, so it might be an issue then, but for casual 30 minute couch sessions it's not a problem for me. Oh yeah the red Aquila strings have a bit more brightness to them according to the website. And according to some reviews they're also less sticky than the thunderguts. Sorry for spamming your channel full of comments, as you can tell I've been binging a lot of your content :P

[@stephencoxbass]

I think the longer scale does help, but it's also only super noticeable on long slides. Thanks for the info on Thunder Reds...I knew about the stickiness, but not the brightness. Thanks again for watching. Cheers!

[@jon_rome_143]

Your videos are incredibly helpful! I'm really hoping to get a Journeyman Ubass(I love the look of the mahogany with the f-holes), but you can only seem to buy them with round wound strings these days, and I really want to use Thunderguts. Do you know if it's easy to switch the strings? I've heard the bridge needs some modification, and I'm not sure I'd trust myself to make any modifications haha.

[@stephencoxbass]

I think you can switch them out fairly easily, but you'll probably have to replace the nut...I don't think the bridge needs anything. I hope that helps!

Hi, thanks for the infos. I'm a beginner to intermediate player. Is it cool to change from rubber to metal strings on the same ubass? Do they come with a truss rod?

[@stephencoxbass]

Most bass ukuleles (and all Kala acoustic/electric U-Basses) have truss rods in the neck already. Rubber to metal should be fine, although most people recommend replacing the nut with one suited for those strings specifically. Thanks for watching!

[@pohjoinenkala9301]

Thanks for the informative video, Stephen! I just bought the metal round wounds model, ebony as it was available. I wanted to buy the solid mahogany one - as long they are still available - but the store could not offer metal strings for it... My new Ubass works well with our garage rock band, the guys liked the sound and versatility of the acoustic model when amplified. No feedback issues so far, aside from the positive fact that the instrument has better sustain when amplified. I'm now considering to buy a mahogany and maybe change strings, or rather maybe not, now that I have the round wounds. Having many basses is... well, basic luxury :-)

[@stephencoxbass]

I think the ebony model looks great, I'd love to get a fretless one! Congrats on the new U-bass!

[@grp4l]

Thanks for doing this comprehensive review on string types. My EKO Fretless U-bass came with Aquila Thunderguts and although it sounded warm and mellow, I had a couple of issues with them. As you said, sliding up on the strings affected the intonation, this seems to be unavoidable. The other issue for me was my fingers tended to stick on the strings. I had no intention of putting lubricant or powder on the strings, so I ended up wearing thin cotton gloves, a bit like Scott does. I play an Epiphone EB3 with Rotosound flatwound Jazz bass strings which slide and produce a warm tone. With that in mind, saved up and got a set of Galli black nylon wrapped flatwounds. They solved both my issues and play well, especially when amplified. The only downside is they are much quieter if unplugged.

[@stephencoxbass]

I'm glad you found this helpful! I still enjoy my flat wounds. Cheers!

[@panr5852]

Wow, I really dig the flat wound strings sound! Question, Steven or others who know, I have a Kala U-bass, solid spruce top model that of course came with the Kala black rubber strings. If I switch to the flat wound, would I need to get a luthier to adjust the nut, saddle or action first? Thanks much!

[@stephencoxbass]

With mine, I had to widen the nut, but the ones designed for the rubber strings should have the right sized grooves for the flats (they are thicker than the round wounds, so a bit more like the rubber). The only reason you might need any adjustments like that is if the string height is too high. I haven't put them on a U-Bass that had the rubber strings yet, but that's my thought on it. I hope that helps!

[@j.r.4627]

I play uke and have been looking for a ubass for while. I wanted one with flat wound strings standard but got a Hadean with rubber strings 'cause the price was right. I thought I changed the strings but you make the rubber sound great. Gives me something to work towards.

[@stephencoxbass]

Thanks! Both strings are great. I'm really enjoying the flats the most, but rubbber do have a certain vibe you can't get from either metal string.

[@VSchwarcz]

Thank you. I needed that info. I bought a Ubass to noodle around on without having to pick up my full size bass. Mine came with the rubber strings, which to me feel so so weird. I’m having a hard time getting used to the feel of them. In your demo, as an alternative, I did like the sound of the flat wound strings and the warmth of the rubber strings.

[@HerroVincey]

Hey Stephen! I come back to this video every so often when the urge to buy a U-bass comes up. I have a strong feeling I'm going to bite the bullet soon HAH. So I've been looking at a solid body fretless Hadean U-bass, I was thinking that perhaps the flatwounds would be best? My reasoning is that roundwounds would tear up the fretboard over time. Also, I feel that the flatwounds sound closer to that vintage p-bass sound which would make it a suitable alternative to those gigs where I don't want to lug my bass guitar. The music my band plays is 70's to 90's pop, funk, and rock. Could you share your opinions/thoughts? Thanks in advance!

[@stephencoxbass]

I personally prefer the flatwounds as well. I know Kala recommended not putting them on their solid body U-basses for some reason...hopefully that same issue is not the case for Hadean. If you try it, let me know how it sounds! Cheers!

[@HerroVincey]

@@stephencoxbass Thanks a bunch!! I guess I can always buy a flatwound set to test out and save the stock strings if needed. I'm not experienced with piezos, so my theory is there could be stronger tonal changes on a solid body. I'll reply back if I find out!

[@FloriManning]

Thanks so much for this video, very informative! Question: if you plan to switch string types, are there limitations/issues regarding how they fit with a setup originally designed for a different kind of string set? For instance, the Kala round wound are considerably thinner than the ‘rubber’ style strings… does it affect tone and playability switching up on the same instrument?

[@stephencoxbass]

It takes some work: when I put flat wounds on, I had to widen the groove on the nut under the E string. Once I did that, they played great. Thanks for watching!

[@jplpagan]

Hey Stephen, thanks for these. Question: you mention EQ'ing out the finger noises on the rubber strings. Do you have a video where you talk more specifically about how you do that?

[@stephencoxbass]

I'm not sure...it might be in a live stream somewhere. Basically it's just taking the treble out as much as possible. If you had an eq pedal with "8 bands" or "16 bands" you could find the specific frequencies that are causing the noise, but with just a bass and an amp, turn the hi or treble down and that should reduce the noise a bit.

[@crevisb1969]

Turning down the treble took out all the weird noise in mine. Boosted the mid a bit

Can the neck of a U-Bass that is originally made for rubber strings withstand either of the metal ones as well without breaking? I absolutely hate rubber strings so i'm thinking of buying something like regular U-bass and replace them with metal ones if possible.

[@stephencoxbass]

As long as the U-Bass has a truss rod, it can handle the metal strings. All of the acoustic/electric Kala U-Basses can take the metal strings designed for the U-Bass. These strings have a nylon core under the metal, so they aren't as hard on the necks.

[@dimiaraujo90]

IMHO: For playing plugged in: Rubber/P.U. For playing acoustic/unplugged: Roundwounds For anything and everything in between: Flatwounds

Not a bad way to look at it. I think the flat wounds are the best of both worlds in a lot of ways. However, the round wounds project better unplugged for sure, and also with harmonics!

Any feedback would be greatly appreciated. Thanks.

[@stephencoxbass]

With the newer type of pickup, I know the fix is to cut the saddle in 4 places so the strings are able to push down on the pickup evenly, but I think you have the other style pickup.

I'm not sure if the flatwounds are the right length for the ashbory, or if the bridge/pickup of the ashbory can handle those strings. Check the scale length of the strings and your bass to see if that works, and then use your best judgment on the pickup/bridge design. Maybe someone in the ubass freaks Facebook group has more experience with this. Thanks for watching!

Hi Stephen, if i understood correctly, the flats as well as the round wounds are thinner gage. How do you compensate that thinner gage on the saddle originally designed for the thicker rubber strings. Any issues here? Thanks for sharing your valuable experience. Cheers

Hey! I put the Galli/Kala metal flat wound strings on my Journeyman. If you want to change yours to polyurethane strings, you may need to buy a new nut intended for those that has wider grooves. If the strings aren't fitting through the holes on the bridge, you may want to see if the string packets mention the gauges of the strings and find a set with a thinner gauge. Otherwise you may need to widen the holes there (which I would try to avoid...). Thanks for watching!

[@synestematic]

nice video man, what about volume (acoustically of course) ? Do you also find round-wounds to be louder than rubber strings ?

Round wounds are definitely louder. Are they loud enough to be in a jam setting with a guitar? Almost...they're still a little too quiet when acoustic, but they are louder than rubber.

[@timskaggs1940]

The acoustic comparison provided some info, but the basses being significantly different (sound hole vs. “f” hole top) was bound to be making a big difference in the sound we the viewers were hearing. Three identical basses each strung with one of string types would have provided a more sonically equal test.

[@stephencoxbass]

True. For the rubber and the round wound's I have a video where I was able to compare strings on the same model (exotic mahogany): kzbin.info/www/bejne/d4nEeYClrJmZrrM . However, I don't know anyone with one with flats. It's hard to just change the strings, as the nut has to be altered For The different strings. If you're curious about rounds verses flats I have videos of the journeyman with round wounds like this one: kzbin.info/www/bejne/Z3usdaOumsyoidk that you can compare with the flat wound demo in the current video. I hope that can answer a few questions.

[@mikeelmo8532]

Do you find much difference in the unplugged sound level between the kala models you play in the video (when using same strings, of course)? I know they need to be plugged in in most settings, but wondering if there is a difference for when i want to mess around on my couch and don't want to plug in.

[@stephencoxbass]

You lose a lot of the power of the low frequencies, but it’s fairly similar otherwise. The metal strings definitely project better unplugged, so you might want to stray from the polyurethane ones to hear yourself better unplugged. Thanks for watching!

[@beckichaplin1974]

I have always loved how flats sound and feel but I did notice they almost sounded muted compared to the other two on this video. I love the ticking on the frets with the round wounds but that doesn’t work for all songs. And they are just too rough for my tender fingers.

Hi Stephen, thanks for all the great information. Do you know if tape wound strings will work on a Kala? like D'addario flat tape wounds or Labella deep talking?

[@stephencoxbass]

That's a great question. I personally would not try it for a few reasons: The gauge is different for full scale bass strings, so they would be very loose on a U-Bass. Also, the tape wounds have a metal core while U-Bass strings have nylon cores, and since the strings wouldn't taper at the ends soon enough, they would put stress on the tuners. If you were to get a 5 string pack to get around the first issue I mentioned, you might amplify the 2nd issue. Maybe one day they will make tape wounds designed for such a short instrument, but I have yet to see any on the market. Thanks for watching!

[@JesusChrist5000]

The rubber strings sound much better. I would definitely never buy round wounds for ANY bass. I don't understand why they are still made and why bassists still use roundwounds.

[@stephencoxbass]

They are just a totally different thing for completely different scenarios. The flats are my favorite at the moment, but if I'm playing slap or Progressive Rock, I prefer the rounds. I prefer the rubber if I'm playing Motown, Jazz, and Blues. They all have a place to me.

[@andyduckering8731]

I love this video Stephen, thank you. I like the Countryman bass body because of the jazz vibe of the f holes but I think I'd like the rubber strings the most because of the closer proximity to an upright bass sound.

[@smdias65]

Thanks for the detailed info! I have a Hadean U-bass and I like the polyurethane strings, but some things (like slapping) just sound better with metal strings, IMO.

I agree, each have their strengths. That's why I have all 3 :)

[@StringsOfBrian]

I have an Amahi 002 EQ Ubass. Will all Ubasses work with any of the three types?

[@stephencoxbass]

I think yours will, although you might want to replace the nut for the round wounds. The strings look like they would fit that Amahi model just fine as long as the scale length is basically the same as the Kalas.

[@rcjd7834]

The PU strings sound much more like a bass acoustically. The other 2 sound like a slightly lower ukulele.

[@stephencoxbass]

I think the rounds sound like an acoustic electric bass guitar, and the flats have a vibe almost like a Hofner Beatles bass. The PU definitely sound more like upright.

[@corycenterassurant6105]

did you have to mod the nut?? or can you just throw the flats on?

I had to file the groove on the nut under the E string to be wider. My U-bass came with round wounds initially, and the flat wounds are wider strings. Great question.

[@andypandy8569]

They have the most attack and mid-high frequencies. If you aren’t bothered by the extra string noise, they are an excellent choice. Thanks for watching!

[@RobVespa]

Thanks for this comparison. It's just what I was looking for. Each string type has it's own pros. This typed, what attracted me to this type of bass (ukulele) outside of the size is that with the "rubber" strings, it sounds akin to an upright bass... so those are my favorite sounding strings. As an aside, the coral colored Kala with the f-holes is nice. I've not seen that color before. All the best!

[@dean-orochester7374]

Stephen will the new flat wounds work on my gold tone microbass it’s 26 inch scale

I'm honesly not sure, they do have a good bit more tension than even the round wounds. Is your bass the same scale as a U-bass?

[@pudifake6848]

I have rubers strings in my ubass, can i change to metal ubass strings? without exploding my bass?

[@stephencoxbass]

Does the U-Bass have a truss rod? And what scale length is yours? Chances are if it has one and is sized right, the metal strings will work.

[@michaelchavka5678]

Using three different instruments to compare three different string types does nothing to present an accurate comparison... Nice try...

[@stephencoxbass]

It does help, as the piezo pickups are very similar between instruments. If you are curious about the round wounds verses flat wounds, compare my journeyman review video to the flatwound sounds in this video. Those are the different strings on the same bass. For rubber vs round wound, I was able to borrow an exotic mahogany from a friend to compare those two on an older video. You can go to my channel and organize the videos by most viewed/popular to find each of those. I plan to make a comparison on the same U-Bass in the New year.

[@arandybozarth]

Extremelly helpful. Thanks! Liking the upright sound and the higher tension so flatwounds seem like a good (and expensive) compromise for what I want to do. Any comment on which Kala U-Bass has a better upright sound? especially Rumbler, Exotic Mahogany and Striped Ebony. Or is the selection of string more important than the specific instrument? Thanks in advance.

[@stephencoxbass]

It's more about the strings and the pickup, so those options might sound similar unless they have changed the pickups on one of those models since I last checked. Thanks for watching!

[@arandybozarth]

@@stephencoxbass Thank you.

[@mp3o]

Is there a short scale bass string type that will work with an "E-Bow" type sustain device?

[@stephencoxbass]

I imagine the main thing for an E-Bow to work is that the strings need to be metal. I have not tried to use one, though. I believe the E-Bow works through a magnet/electromagnet causing the string to vibrate. Thanks for watching!

[@jburtonca]

Hi Stephen. I have used the Thunder Reds on my Kala Acoustic for about five years and they are by far my favorite non-metallic string for the U-Bass. They are thinner than the Thunderguts, not as sticky and have a punchier tone that is still very upright-like. I use a plastic container with a sponge soaked with mineral oil that I dip my fingertips in. This virtually eliminates string noise and lets the fingertips of my right hand release the strings smoothly which greatly improves the tone. On my solid body SUB I use the Galli UXB 810 Blacknylon strings. They sound and feel great and really last. I've had them on since last December and there is still no wear on them. I found that the Kala roundwounds are to soft and thin and the frets and my acidic hands tear through them very quickly. I also want top say that both the Galli flat wound and Galli nylon roundwound contain steel and should work with magnetic pickups for those with the skills to install them in a Kala solidbody.

[@stephencoxbass]

Thank you for all the info! I never would have thought to use mineral oil. In the future I may have to see about trying to install the type of pickup you mentioned...that should reduce string to fret noise a bit, too.

[@jillgeary1313]

I agree - the Thunder Reds are less sticky than the Thunder Guts. Thinner too. I've had hand issues so, experimenting, I've used Gorilla Tips on my left hand fingertips, then wear a tight-fitting silk (or cotton) glove over that - I can slide easily on the Thunder Reds and my fingertips are protected (which I need b/c of my injury). I'm considering the Flats but the added tension concerns me....

[@markuyehara7880]

Great review. BTW, it's pronounced "pa-ho-eh-ho-eh".

[@stephencoxbass]

Thank you. Cheers!

[@9jmorrison]

The instrument should be the same to really sense the string difference, and how did they feel to you?

[@stephencoxbass]

True, but all of these instruments have a piezo pickup, so the sound is fairly similar between the different models in spite of the differences. My preference overall is the flatwounds, since they slide smoothly and have less of the clicking noise. However, the round wounds are my go to for slapping and feel the most like electric bass strings, and the polyurethane are good for Motown songs and emulating an upright bass though they feel a bit sticky. Thanks for watching!

[@loictrocme2764]

Hello. I change the strings to metal roundwound, and I have now a very high action (about 10mm). The neck is just slightly bent as it should, so I imagine truss rod would not help. any idea how to solve this? Thank you

[@stephencoxbass]

Hello, and thanks for watching! You might need to file down the nut and/or the plastic insert under the saddle/pickup in order to lower the action. The downside is that you can't go back to polyurethane strings easily if you make these modifications. Kala recommends changing the nut out for one intended for the round wounds as well. I hope this helps or at least gives you some ideas. Cheers!

Stephen... Great Comparison video! I just subscribed to your channel a couple of weeks ago, as I happen to come across some reviewing videos on the KALA U-Basses, as I was researching information on them. I have a question for you, Stephen.. I am looking into purchasing a KALA U-Bass to add to my 3 electric basses (and 4 Lap & console Steel Guitars.... and 9 harmonica's. lol), in my quest for as close to an Upright bass sound as I can get, for playing Country, Country Gospel, Western/Texas Swing & Bluegrass. Which of the Kala U-Basses and String combinations, would you consider to best fit that "wish list" for that Upright / Dbl Bass sound?? Also, is there Really any appreciable difference in sound, quality and overall longevity, between the "Fishman" (made in Mass. USA) electronics on the "higher end" ($429.+) KALA U-Basses, and those on the next step down ($300. - $400.), that would make it a "game changer" to "own the best they have"?? In other words, and besides the type of woods used on the different models.... do I really "need" to spend $449. to get the best Upright bass sound from the Mahogany or Ebony U-Basses, or can I get the same sound & Quality from a $300.+ U-Bass? Are the $449.+/- U-Basses with the Fishman electronics, and the HipShot tuners (as nice as they are) really worth the extra money, in comparison to the slightly lower price range and their components?? I CAN afford them.... but, is it really necessary to do so, and get what I'm looking for in sound and longevity?? I am Not currently playing with any bands... and am now 73 years "young", so I'm now playing for my own pleasure, and jamming with others, who are also "getting up there" in their years, but have also been playing for decades as well. Thank you in advance, Stephen... for your time and any experienced insights and suggestions you can make in helping me with my decision in acquiring my first (and most likely, Only) U-Bass from KALA... your response will be Greatly appreciated, and taken into consideration of which one I choose to purchase. I will let you know which one I get...... IF, it's even in stock. At the moment, it's seems they're Out of Stock on just about All of them (11.14.2022 on the KALA website store), except for the two High End models, and the one for $389.... unless they have more for sale on other online websites or dealers... like Sweetwater or possibly even Guitar Center, etc, etc.... but I would prefer to buy directly from them. Thanks Again.

[@stephencoxbass]

Thanks for watching! You would probably be happy enough with any that come with the polyurethane strings, but I do feel like it can be worth the step up for quality and quality control on the more expensive models. I thought the Pahoehoe strings sounded the most like an upright, but there are more options at this point I have yet to try. I hope that info helps a bit. Cheers!

[@stephencoxbass]

P.S. I don't know if any of it is a "game changer" specifically, but I would probably spend the extra for the upgraded pickup if I were only getting one.

[@Romans--bo7br]

@@stephencoxbassThank you Stephen for your reply.... I really appreciate it and your thoughts on it. I found a Mahogany U Bass used on a site, but it does Not have the Fishman electronics, I think it might be an "older" model, and it has Kala round wounds on it, although it comes with a New set of Aguila Thundergut strings (new, in package), as well as the Kala Custom Bass Bag, and a 2" Velvet strap (New) - all for less than $400. I haven't moved on it yet... but thinking I will... Soon. I was looking at some of the Rondo/Hadean versions.... and the prices are certainly "right".... but, I don't trust them for any kind of worth while quality. I also looked at the Luna line... No Truss rods... I don't like that. The Lanakai's looked good, but I don't care for the way they're set up with those Phosphorus Bronze strings.... not "bassy" enough for me. Not much sense in going "cheap" then have to turn around and spend another $150.+/- to make it "right". So, will most likely stick with the Kala.

Gil, were the original polyurethane strings that you like so much the white Aquila ones or the black Kala ones? Clearly on the Kala website, some of the U-basses come with Aquila strings.

[@giljusino]

My original strings were the black ones. I’ve enjoyed them since I bought the instrument in 2014. My main bass is a 3/4 size upright bass. I love the Kala for its size & sound. However, recently I changed strings on all my basses, including the Kala. I put the new flatwounds on it. Wow, once again I’m very impressed with its sound. Much louder when not amplified, but I’ve lost the upright bass tone. It sounds like most acoustic, guitar size basses. For me it’s a toss up on the next string change. BTW, I had to replace the nut when I converted to flatwounds, as they are thinner and buzzed with the original nut.
