On trolls and truss rods, braggadocio and bridges: follow-up on my “first impressions” YouTube video about the Fender American Ultra Jazz Bass

Whew, that title is worthy of a master’s thesis. (Note: The majority of what follows is adapted from the script I wrote for a follow-up video that I have since decided not to make.)

About 3 months ago, I bought a Fender American Ultra Jazz Bass, and the day I took it out of the box, I made a YouTube video demoing the instrument and giving my first impressions:

In the time since I made that video, I’ve played the bass a lot, and I’ve had some ongoing frustrations with one specific aspect: I just can’t seem to get the action set to my satisfaction. The frustrations were exacerbated by a comment the video received last week, criticizing the high action on this bass due to the Fender Hi-Mass bridge… and also my abilities as a player.

Feeding the trolls

I’m not thin-skinned, but I do take criticism to heart. I know I’m not the most technically dazzling player, and I don’t aspire to be. I’ve been playing bass since I was 15 — that’s 34 years, if you’re into math — but I’ve never become a “shredder” for three reasons:

  1. I just don’t have the manual dexterity for it, especially as I’m getting older.
  2. I have not made my living as a professional player, so I have limited time (and motivation) to practice.
  3. Flashy technique is not the pinnacle of good bass playing.

I want to focus for a minute on that last point. Yes, technique matters. But playing fast is rarely the most important part of playing bass. Tone, groove, and fitting into the context of the rest music, where the bass is almost never the focus, are all, I would argue, far more important than ripping 32nd note runs at 200 BPM. Of course it depends on the genre, and on your goals as a musician.

These are my goals as a bassist: to play with a good tone, to lock into the groove, and to play lines that fit the music. And I think I’m in good company.

No, I am not implying that I am anywhere
near as good a bassist as Tony Levin.

I’m saying that he prioritizes the
music over flashy technique.

(Also, when he does want to do the flashier
stuff, he uses the Chapman Stick.)

There’s also a fourth factor limiting my bass skills: since I’m a multi-instrumentalist, I’ve never tried to express all of my musical ideas on the bass. Playing other instruments has given me a measured perspective on the role of the bass in my own music.

OK, enough feeding the trolls. But even trolls sometimes make good points, and there is definitely a point here: even with the 10% discount I received from Fender, I expect a little more for $2000 than what I got with the Fender American Ultra Jazz Bass.

First impressions should never be made in the dead of winter

When I made the initial demo video, the bass had just arrived 24 hours earlier. (I let it sit for a day because it was the middle of a classic Minnesota January “deep freeze” where the high temperature was -8ºF.) I literally took it out of the box on camera. I shot the entire video, including doing what setup I could on a bass that was still adjusting to a new climate, that afternoon. I hadn’t had time to get to know the bass and really learn its strengths and weaknesses. Now that I’ve had it for three months, I understand it better.

There are a lot of really great things about this bass. But there are problems too. I’m judging it against my 2018 Fender American Professional Precision Bass. That bass, to me, is perfect. I mean, the Precision Bass and the Jazz Bass are very different beasts. But in terms of build quality, my American Professional P-Bass is as good as I’ve ever seen with a production instrument.

When I decided to get a Jazz Bass early this year, I admit I was swayed by the “Ultra” label… I decided that if I was going to spend a good chunk of money on an American-made Jazz Bass anyway, I might as well get the best production instrument Fender makes.

Well… OK. I will admit it. It’s (probably) not.

You can’t always get what you want

I used to want an American Elite Jazz Bass:

Then, Fender replaced the Elite with the Ultra. Overall, it seemed like mostly a lateral move. One really odd thing though, was the switch from the modern 3-screw high-mass bridge — the one that’s in my P-Bass — to the chunky 5-screw Hi-Mass bridge. Especially since it eliminates the string-through-body option. (They also changed the truss rod access in a way that definitely seemed like a cost-saving downgrade.)

This is the same bridge I had bought from Fender’s parts department to install on the “Frankenstein” fretless Jazz Bass I assembled a few years ago. It’s decent, but it’s not as nice as the 3-screw bridge, although it has the benefit of being drop-in compatible with the classic 5-screw bridge design, so it increases the mod potential.

But… who wants to mod what’s already supposed to be the “Ultra” bass? Hmm…

The bridge or not the bridge? Many factors affect the action

The Fender Hi-Mass bridge on the Ultra is chunky, and it affects how low you can set the strings. But how much does that really matter? Today we’re going to find out.

What is the goal of adjusting the action — a.k.a. the string height? Most players I know want the strings as low as possible, because it makes it easier to play fast notes… or really, just easier to play in general, because you’re not having to press the strings down as far, or as hard, to cleanly fret the notes.

I definitely want low action, because I want it to be easy to play. But the lower the action, the more likely you are to get fret buzz. Why? When you’re fretting a note, you’re basically creating a very long, thin triangle between the string, the bridge, and the neck.

Buzz happens when the vibrating string makes contact with other frets, so you need the angle between the string and the neck to be just large enough to keep the string from making contact with other frets. There are three ways to minimize buzz: adjust the truss rod to add curve to the neck, raise the bridge saddles, increasing the length of that “side” of the triangle, or… pluck gently, so the strings don’t vibrate as much!

It sounds like a joke, but the last point is important… turn up your amp and use a light touch, and you can really help this problem. It’s the only solution that doesn’t result in higher action. Still… this has been gnawing at me for 3 months with this bass. I’ve tweaked the truss rod and the saddles a bunch of times, tried modifying my plucking technique, and I just can’t get to a buzz-free sound without high action.

Some who have criticized Fender’s design of the Ultra Jazz Bass cite the height of the bridge as the problem, but I’m not convinced that is it. I can very easily lower the saddles and adjust the truss rod enough to get satisfactory “low action” on this bass… but at the cost of terrible buzz.

So, is it the bridge? We’re going to find out. As I mentioned earlier, I bought one of these bridges for a fretless Jazz Bass I was putting together — which, incidentally, I sold to help pay for this bass. The body of that bass was a Squier Classic Vibe ’60s Jazz Bass in Daphne Blue. I still have the stock bridge that came with that Squier. And now I’m going to install it on my American Ultra Jazz Bass, to see if a different, thinner bridge design can solve the problem of the high action on the Ultra Jazz.

Yes, I’m modding my Fender American Ultra Jazz Bass… by installing the bridge from an Indonesian-made Squier. Here we go.

Or… maybe not

That was the end of my prepared script for the video. The rest was going to, necessarily, come after I had swapped the bridge, which I was planning to do this morning as part of producing the follow-up video.

I woke up this morning not really wanting to spend the entire day making a video, not really wanting to swap the bridge on my Ultra Jazz, and… after having some coffee, realizing that I was still feeding the trolls (this post is too, but at least it’s less effort). I thought back to those diagrams of the “triangle” (which were still just images in my head at the time). And more importantly…

I realized that there was no possible way that swapping the bridge would help the situation.

Think about it: if the complaint is that the bridge is too thick, then I should already have the saddles bottomed out. Specifically, the action should still be too high when the saddles are bottomed out. And I’ve already verified that’s not the case. If I lower the saddles on the Hi-Mass bridge all the way, the action is fine. Beautifully low. But there’s terrible buzz. Putting on a different bridge that lowers the strings even more isn’t going to get rid of the buzz — it’s going to make it worse.

Clearly the issue I have is different. And it could probably be chalked up to my lack of expertise in guitar setup. The problem most likely could be fixed with a more careful truss rod adjustment, or possibly by shimming the neck.

I don’t have a caliper, so I can’t take a super-precise measurement of the string height. But I got out a tape measure and I compared the string height at the 12th fret on both the P-Bass and the Jazz.

String height on the Jazz Bass

It’s a bit hard to see because of the camera angle but… yeah, they’re pretty much the same. Within a millimeter of each other, at least. On both basses, the bottom of the E string is about 4 mm from the fretboard. (Yes, that is from the fretboard, not the top of the fret itself. It was just easier to measure this way, in this moment.) Both basses are set up fairly well in terms of fret buzz — not absolutely perfect, but little to no buzz unless I’m really plucking hard.

So… uh… what? The action isn’t really unusually high at all. It’s just my perception. But why is that?

I’m not saying it’s the strings, but… it’s the strings

The one factor, I think, that is making the biggest difference here is the strings.

I’ve had these La Bella gold flats on the P-Bass for about 6 months. I think they sound good, but I don’t really like them otherwise, for two reasons: first, they have a much higher tension than I’m used to, so it kind of hurts to play them after a while. And second, the alloy seems to have corroded slightly on the surface, making the strings a bit “sticky” to play, and they leave a distinctive metallic smell (and sometimes even black residue) on my fingers when I play.

I discovered the joys of tapewound strings during my shortlived ownership of a Schecter Stiletto Studio bass last year. (That bass had its own unique problems so I returned it.) When I got the Ultra Jazz, I immediately replaced its stock strings with these La Bella “white nylon” tapewounds. They are super-smooth and a joy to play. They are also much lower tension than the gold flats. I am now convinced that this is probably the biggest reason why I’ve had more issues with fret buzz on the Ultra Jazz than on the P-Bass.

I’m not in a huge hurry to test this theory though, for one kind of silly, superficial reason. I really like the look of the silk wraps on the ends of the strings, but I’ve learned that if you remove the strings, that silk frays really easily. So I’m trying to avoid removing these strings unless I absolutely have to.

Fortunately, for my next mod, I won’t. I’ve got a wild looking replacement pickguard coming next week. I can’t wait to see how it looks. (And, if it looks like crap, it’s easy to go back!) For now, those measurements I took are easing my mind.

Update (May 4, 2023): After I posted this, I continued to encounter some fret buzz issues, so I decided I would go ahead and try different strings. I had a set of D’Addario “half rounds” sitting around that I hadn’t tried out yet, so I put them on. They were better, but the E string was completely dead. Utterly useless… plunky and zero sustain. So I did a bit more research and decided to try DR flats. At least they call them “flatwound” but they seem almost more round than the D’Addario “half rounds”. Anyway, they’re much nicer, and seem to suit the instrument quite well.

Also… here’s that crazy pickguard I mentioned:

A detailed look at my “Frankenstein” fretless Fender Jazz Bass

I got my first bass — a black Fender Standard (MIM) Jazz Bass — when I was in high school. It wasn’t perfect, but it was a great starter bass. And even though I didn’t really like the black body — I’ve always found black and sunburst to be the most boring and overused guitar finishes — I loved that bass until I could afford to buy a better one, ten years later.

But I always felt like that bass was flawed because of something that was my own fault. I was a curious kid, and one night I decided to take the bass apart. I mean, absolutely as far apart as I could. I removed the strings, the neck, the pickguard, the control plate, the pickups, the bridge… I think I even removed the tuning machines and bridge saddles. And then I put it all back together again.

But I didn’t know what I was doing. I didn’t know that the pickup height should be adjusted for optimal volume balance, so I just cranked them all the way down. I didn’t know that the bridge saddles needed to be adjusted in two dimensions for optimal tuning and playability, so it was out of tune and had terrible action. I didn’t know that the neck tension rod should be adjusted so there was just the slightest concave curve to the neck, so I had fret buzz.

Basically, I just thought it was a mediocre instrument, when in fact I had made it that way.

The lesson I learned was that I should not make any adjustments to my instruments, and it took me decades to get over that.

Fast forward to 2019. I’ve been playing bass in a jazz quartet for a couple of years now, and I’ve been buying new basses! For the past decade I’d owned a really nice Fender Jaguar Bass (MIJ) — red with matching headstock and block inlays — and a kind-of-crappy 5-string MIM Jazz Bass. I decided since I was playing jazz, I needed a fretless, so I went for a minimal expenditure and bought a Squier Vintage Modified Jazz Bass.

I couldn’t believe how good the Squier was for the price! Better than my MIM Fender! So I decided to sell the 5-string. I was hardly playing it anyway. I was curious about short-scale basses, so I bought a MIM Fender Mustang. But I hated it. The quality was crap. I don’t know what’s going on in Fender’s Ensenada factory these days, but I’m not impressed.

For those who don’t know, Squier is Fender’s entry-level sub-brand. Originally a mid-level line made in Japan, then for many years they were very poorly made in China. These days, I’ve since learned, they’re mostly made in Indonesia, using mostly CNC robots (rather than overworked and mistreated human laborers) to keep costs low but consistency and quality much higher than their reputation would lead one to believe.

I also realized short scale was a bad choice if I was simultaneously trying to regain my feel for fretless, so I returned the Mustang and bought… a Squier Vintage Modified 5-string Jazz Bass. It’s also surprisingly great!

Then earlier this year I sold the Jaguar and upgraded to my first ever Precision Bass, an American Professional. It looks just like the bass I learned on that I borrowed from my high school, before I got that first black Jazz Bass. I love it!

But that got me thinking… now that I have a nice solid American Professional instrument, I wanted to tinker a bit with another bass.

As good as the Squier fretless was, I hated two things about it: the synthetic fingerboard material (it just didn’t give enough of a “woody” sound), and the boring sunburst finish. (See above.) By now I’m comfortable adjusting the neck tension, action, tuning, and pickup height, so the idea of doing some customizations (just not to my expensive American Professional!) is not intimidating anymore.

For 2019 Fender introduced a new “Classic Vibe” Squier series, and there I saw the bass of my dreams… a “Daphne blue” Jazz Bass. But it only came in fretted. So I decided this would become the basis for my Frankenstein monster!

Fast forward a few more months, and now the monster is complete. Pretty much the only parts of it that are still the original Squier are the blue body, the tortoise shell pickguard, and the control plate. Everything else is new, with the exception of the tuning machines, which I stole off the Squier fretless (I’ll get to that).

I just love that look of the Daphne blue body paint with the tortoise shell pickguard. That was the inspiration to make all of this happen!

Yes, there’s a bit of headstock vanity, as much as I’m ashamed to admit it… gotta have that Fender logo! But the main reason I wanted this Fender neck, instead of just sticking the Squier fretless neck I already had onto this (which I did, initially), was to get that nice rosewood fingerboard.

Funny thing… when you buy a stock neck from Fender, they really just send you the neck. It just has 4 holes in it for the tuning machines, but you have to supply those yourself. I could have bought a set, but I figured I’d just use the ones from the old Squier fretless neck that I didn’t need anymore. Of course, the screw holes didn’t line up quite right, so I had to drill new ones.

Nuts. The other thing about the stock neck is that the string grooves in the nut aren’t really there… just little pilot notches. You’re supposed to file it down yourself. But a set of nut files is like $80! I considered buying some, but then I learned that this synthetic nut material is soft enough that you can actually “file” it with a set of roundwound strings… so that’s what I did! (I play the fretless with flatwounds.) It’s not totally perfect, but it worked surprisingly well and didn’t cost a thing!

Seriously? Did I really need to swap out the neck mounting plate? Well, yes and no. No, of course I didn’t. But I kind of wanted to, to get rid of any traces of “Squier.” But there was actually a good, practical reason for this. I wasn’t 100% sure the screw holes for mounting the neck would line up properly between a Squier body and a Fender neck. I was pretty sure they would. But not positive. This was an inexpensive (about $15) way to confirm that it would work, before spending a couple hundred bucks on a neck. It worked!

A Fender hi-mass bridge. The stock Squier bridge was perfectly fine, but I didn’t care much for the changes they made to the bridge saddles with the Classic Vibe series. Initially I swapped in the saddles from the Vintage Modified fretless, but a hi-mass bridge is not a huge investment and it does improve sustain… plus it just looks better.

DiMarzio noiseless pickups. Without a doubt this was the best upgrade across the board. The stock pickups just had kind of a weak and undefined sound… it was impossible to get that classic Jazz Bass “twang” from the bridge pickup. Plus you could never really solo one pickup because the 60 Hz hum was awful! These pickups are a lot hotter than the stock ones and give a very distinctive tone. But most importantly, they’re wired as split coils so there’s absolutely zero hum with one pickup soloed!

Of course, there’s always something. These pickups are taller than the stock ones, and they couldn’t be seated low enough to have the proper distance from the strings. I needed to rout out the body cavities deeper for them. But I don’t own a router, or a drill press, or anything that you should probably have to do this job right. But I was determined to handle this the way I’ve handled everything else on this project: fast, cheap and out of control. I found the most suitable bit I had on hand for my hand drill, and set to work removing wood. The end result was pretty ugly (and honestly, still not quite deep enough), but it’s hidden, and now things look and sound great!
