What Setting Up a Guitar Taught Me About Accessibility Work
A guitar setup is a series of small adjustments that nobody notices individually and everybody feels together. Neck relief, action height, intonation, nut slots. Accessibility work is the same kind of work. No single fix is impressive. The cumulative effect is whether the thing is playable at all.
What actually happens in a setup?
I did one on my old Les Paul a few weeks ago.
Here's the order, roughly.
- String gauge first. Everything downstream depends on it. I went with .010 to .046, because changing gauge changes tension, and tension changes everything you're about to measure. Decide this before you touch a truss rod, not after.
- Neck relief. Capo at the first fret, hold the string down at the last, and measure the gap at the eighth. I want somewhere around .008 to .010 of an inch. Not flat. A neck with zero relief buzzes, because a vibrating string moves in an arc and needs room to do it. Truss rod adjustments are a quarter turn at a time, then wait.
- Action height. Measured at the twelfth fret, saddle by saddle. Roughly 4/64 on the high E and 6/64 on the low. Lower is easier to play and buzzes sooner but I like a little buzz. There is no universal right number though, only the lowest you can go before it rattles for how you actually play.
- Nut slot depth. This is one you can ruin. Slots cut too high make the first three frets feel awful and play sharp. Cut one too deep and you're gluing in a shim or buying a new nut. You take almost nothing off, check, and take almost nothing off again.
- Intonation at the twelfth fret. Compare the twelfth-fret harmonic to the fretted note. Sharp, move the saddle back. Flat, move it forward. Retune, check again. Repeat until they agree.
None of this makes the guitar sound like a different guitar. It just makes it stop fighting you.
How does that map to accessibility work?
Relief is heading structure. It's invisible. Nobody looks at a page and admires the H2s. But it's the curve everything else sits on, and if it's wrong the whole thing buzzes in ways that are hard to trace back to a cause. A screen reader user navigating by headings is doing the same thing your hand does moving up the neck: relying on a shape they cannot see to know where they are.
Action is contrast and cognitive load. Action too high doesn't make a guitar unplayable. It makes it exhausting. Beginners with high action quit and tell you they weren't musical. They were fine. The instrument was hard. Text at 3.5:1 doesn't lock anybody out either. It just makes reading your page cost more than it should, and people leave without filing a bug report that says "your contrast was tiring."
Intonation is semantics. Everything sounds right at the first fret. Open chords are fine. Then you play up at the twelfth and it's sour and you don't know why. That's a div with a click handler. It looks like a button, it works with a mouse, it's fine at the first fret. Then somebody arrives with a keyboard or a screen reader, which is the twelfth fret, and the wrong note has been in there the whole time.
Nut slots are the thing you can make worse by touching. Every accessibility program has one: the remediation that broke something, the "fix" that added an ARIA attribute which silenced an element entirely. Take a little off. Check. Take a little more.
Where the metaphor stops: a guitar has one player and you can hand it to them and watch their face. A website has thousands of people you will never meet, using tools you do not have installed. So you cannot rely on feel. You have to test, and you have to ask, and you have to accept that your own hands are not the measurement.
So who is any of this for?
I have never once had someone pick up a guitar I set up and say "the relief on this is dialed in." What happens is they play it longer than they meant to. They play something they wouldn't normally attempt. They hand it back and say it feels good. The entire vocabulary most players have for six separate adjustments measured in thousandths of an inch is simply...feels good.
Accessibility work plays out the same way. Done right, it's a person who booked the appointment and never knew a decision had been made on their behalf. No thank-you email. No case study. They just did the thing they came to do.
The player who never had to think about it is the whole point. If they had to think about it, I hadn't finished.
That's accessibility in a nutshell. Small adjustments, in order, measured, on something somebody else is going to use without ever knowing you were there.
Key points
- A guitar setup is neck relief, action height, nut slot depth, and intonation, and no single adjustment is impressive on its own.
- Relief maps to heading structure: invisible, structural, and everything else sits on it.
- Action maps to contrast and cognitive load, where the failure is exhaustion rather than a hard block, and people quit without telling you why.
- Intonation maps to semantics: fine at the first fret, sour by the twelfth, which is where keyboard and screen reader users arrive.
- Nobody notices good setup work or good accessibility work, and a person completing their task without thinking about it is the entire point.
