Do Bigsbys Actually Stay in Tune?
Do Bigsbys Actually Stay in Tune?
Short answer: yes, a Bigsby will stay in tune — but only if the rest of the guitar is set up to let it. And on most of the Bigsby-equipped guitars that come across my bench, it isn't.
"Great guitar, but it's got a Bigsby, so it won't hold tune." I've heard that from buyers, sellers, and people who should know better. It's mostly wrong, and wrong in a specific, fixable way: the Bigsby is almost never the thing causing the problem. It's the thing that reveals the problem.

A Bigsby is a spring, not a locking system
The mental model people bring to this is the Floyd Rose — a system engineered to clamp the string at both ends so it physically cannot slip. A Bigsby is the opposite philosophy. It's a rocking bar on a spring, and the string just sits on it. The whole thing depends on the string sliding freely and returning.
Push the arm down and tension drops. Let go and tension comes back. If the string moves smoothly across every contact point in both directions, it lands back where it started and you're in tune. If it hangs up anywhere — even slightly — tension redistributes unevenly between the segments of the string, and you come back sharp or flat. That's the whole mechanism. Tuning instability on a Bigsby guitar is a friction problem, essentially always.
Illustration: the four places the string can bind. They are not equally guilty.
It's the nut. It's almost always the nut.
From what I see on the bench, the nut is the culprit in the large majority of "my Bigsby won't stay in tune" guitars.
The reason is geometry. A saddle is an open groove the string sits in; a nut slot is a channel the string sits inside — the tightest, most enclosed point on the string path. Cut too narrow for the gauge, cut at the wrong angle, or just left rough, and the string binds. You can usually hear it: that little "ping" when you bend or use the arm is the string breaking free of the slot and jumping to a new tension. That's your tuning going out, audibly.
It's also why the first fix people reach for — locking tuners — so often does nothing. Locking tuners solve slippage at the post. They don't solve binding at the nut, which is upstream of the post. I've watched people spend real money on tuners for a problem sitting a quarter-inch from where they installed the solution.
The real fix is unglamorous: slots cut to the correct width and angle for your gauge, polished smooth, with a bit of lubricant in them. On an otherwise well-set-up guitar, that one job is often the difference between "unusable" and "fine."
The unglamorous end of the problem. Slot width, slot angle, and how cleanly the string turns toward the post matter more here than the brand on the tuners.
The bridge is the second place to look
A standard tune-o-matic saddle has a fixed groove. The string drags in it every time the Bigsby moves, and on a guitar that gets a lot of arm work that drag eventually wears a notch, which makes it worse.
This is the legitimate case for a roller bridge, where each saddle is a small wheel that turns with the string instead of resisting it. The honest tradeoff: some players feel they cost a little clarity, and cheap ones rattle or seize. But on a guitar you actually use the arm on, a good one is a real improvement — a legitimate mod, not a myth.
The tension bar: a tradeoff, not a defect
Some Bigsby models (B5, B7, B12) have a tension bar — an extra roller pressing the string down between the bridge and the string axle. Others (B3, B6) don't.
The bar exists for a good reason: it increases break angle over the bridge, keeping strings seated and stopping them popping out of the saddle grooves under hard playing. That matters most on flat-tops, where the geometry would otherwise be shallow. The cost is one more friction point, pressing hard — so tension-bar Bigsbys feel stiffer and are more sensitive to setup. The forums treat this as a scandal; I don't. Plenty of them stay in tune perfectly well. If yours is fighting you, sort the nut first, then look at how close the bar sits to the bridge — the closer it is, the more aggressive its effect.
Hollowbodies have one extra problem
If the guitar has a floating bridge — held in place only by string pressure, not pinned or screwed down — you have a variable solidbody players don't. Work the Bigsby enough and the bridge can creep. When it moves, intonation moves with it, and you'll be chasing something that was never really a tuning problem.
Pinning the bridge is the standard answer, and on a guitar that gets regular arm use it's one of the better things you can do to it. Some Gretsch models come pinned from the factory; plenty of older and budget ones don't. Check before you blame the vibrato.

What a Bigsby genuinely can't do
I don't want to oversell this. There are honest limits, and they aren't setup issues:
- Range is small. It's a shimmer-and-wobble device — subtle vibrato and a gentle dip. No dive bombs, and no setup work will change that.
- It adds real weight. A B5 runs around 10 ounces, a B7 closer to 12 or 13. That's most of a pound on the lower bout of a guitar that may already be heavy, and it shifts the balance.
- Restringing is a chore. The ball end sits on a pin and wants to fall off while you're getting tension on it. Everyone develops their own trick. It never becomes fun.
- Break a string and you're done. Same as any non-locking system.
Those are fair reasons to skip a Bigsby. "It won't stay in tune" isn't one, because that part is fixable.
What I'd check before buying one used
- Listen at the nut. Tune up, work the arm gently, listen for pinging. If you hear it, the nut needs work — a modest, known job, and leverage on price.
- Check return to pitch. Push the arm down, release, see where it lands. A well-sorted Bigsby comes back reliably.
- Look at the saddles. Deep notches or visible groove wear means the strings have been dragging a long time.
- On a hollowbody, check whether the bridge is pinned — and look for witness marks in the finish showing it has wandered.
- Check the mounting. Bigsbys get retrofitted a lot. Look for filled holes from a previous tailpiece, sloppy screw work, or a unit sitting crooked to the centerline. A bad retrofit is a much bigger problem than a bad nut.
None of the first four are reasons to walk away — they're reasons to negotiate, then spend a little on a proper setup. The last one deserves more scrutiny.
My honest take
The Bigsby's reputation comes from being blamed for exposing flaws it didn't create. A guitar with a badly cut nut goes out of tune whether or not there's a vibrato on it — you just notice faster with one, because you're actively moving the string. Set one up properly and it does what Paul Bigsby designed it to do in the late 1940s: a slow, singing wobble no other vibrato quite replicates. That's why the design is essentially unchanged after seventy-odd years. Just don't buy one expecting a Floyd, and do budget for a setup.

FAQ
Will locking tuners fix my Bigsby's tuning problems?
Usually not. Locking tuners prevent slippage at the tuner post, but the common failure point is binding in the nut slot, which happens before the string ever reaches the post. Sort the nut first; if drift remains, then consider tuners.
Do I need a roller bridge with a Bigsby?
You don't need one, but if you use the arm regularly it's a worthwhile upgrade. It reduces drag at the saddles and slows groove wear. Buy a decent one — cheap roller bridges rattle or bind, which defeats the point.
Is a tension bar Bigsby worse than one without?
Not worse, different. The bar improves string seating over the bridge at the cost of a stiffer feel and one more friction point. Both types can be made to stay in tune. Setup matters more than which model you have.
Does adding a Bigsby hurt a guitar's resale value?
It depends on whether it was factory-fitted or retrofitted. A factory Bigsby is just a spec. A retrofit that required drilling into the body — especially on a desirable instrument — narrows your pool of buyers and typically costs you money, no matter how tidy the work is.
