Best Guitar Capo
A capo clamps across all six strings at a chosen fret, raising the pitch of all strings by the same interval. This lets you play open-chord shapes in higher keys — essential for matching a singer's key or changing a song's feel without learning new chord shapes.
What to Look for in a Guitar Capo
Ease of use: Spring-loaded capos (Kyser) open and close with one hand in under a second. Screw-tension capos (Shubb) require two hands but apply more precise tension.
Tuning accuracy: Cheaper capos apply uneven tension across the string width, bending the strings sharp. Premium capos (Shubb, G7th) apply even pressure and minimise pitch shift.
String clearance: The capo must press cleanly across all strings without buzzing. The underside padding must match the fretboard radius of your guitar (acoustic radiuses differ from electric).
Neck clearance: The capo body must not contact the neck when positioned — excess contact can cause buzzing or prevent clean placement.
Best Guitar Capos
Kyser Quick-Change — £19 | Best Overall
The most widely-used capo among professional gigging musicians. Spring-loaded, one-hand operation — open with the thumb, slide to position, release. No adjustment needed. Works on standard acoustic and electric guitar necks.
Best for: Live gigging where you need fast capo changes mid-song. Straightforward, no fiddling.
Note: The spring tension is preset — slightly higher than optimal for light-gauge strings, which can cause minor tuning shift. Re-tune after placing.
Shubb C1 — £24 | Best for Tuning Accuracy
Screw-tension mechanism that lets you dial in exactly the right amount of pressure. Apply enough to fret cleanly; no excess pressure that bends strings sharp. The most accurate capo for players who prioritise staying in tune.
Best for: Studio recording and acoustic solo players where tuning accuracy is critical.
Note: Requires two hands and a few seconds to position and tighten — not ideal for rapid live changes.
G7th Performance 3 — £40 | Best Premium Capo
Adaptive radius technology — the capo pad conforms to the fretboard curve for even pressure across all strings. Single-hand squeeze operation with a locking mechanism. Made in the UK.
Best for: Players who want the best possible tuning accuracy and single-hand operation. The premium choice.
D'Addario NS Artist — £20 | Best Budget Premium
Tension adjustment wheel on the side. Works well on both acoustic and electric guitar. The micrometer-style tension control means you can set and repeat the correct tension. Good build quality at an accessible price.
Best for: Players who want tension control without paying for the G7th.
Capo Position Guide
Capo at fret 1: Raises all open strings by one semitone (half step). Standard E shapes become F chords.
Capo at fret 2: Raises by a full tone. Standard G shapes produce A chords; D produces E.
Capo at fret 5: Raises by a perfect fourth. Standard C shapes produce F chords.
Common capo positions used in popular songs:
| Position | Open G becomes | Open D becomes | Open E becomes |
|---|---|---|---|
| Fret 2 | A | E | F# |
| Fret 4 | B | F# | G# |
| Fret 5 | C | G | A |
| Fret 7 | D | A | B |
Capo Types
Spring-loaded (trigger): Kyser, Dunlop 83CB. Fast, one-hand operation. Slight tuning compromise from preset tension.
Screw tension: Shubb C1, C2. Precise tension control. Two-hand operation, slower to position.
Partial/cut capos: Cover only 2–5 strings. Used in specific alternate tuning approaches — most commonly the cut capo across strings 2–5 at fret 2 (DADGAD-like voicings). Niche use case.
Roller capos: Can stay on the guitar and roll to different fret positions. Generally lower precision than spring or screw capos.
Classical Guitar Capos
Classical guitars have a wider, flatter neck (52mm nut width vs 43mm for steel-string). Standard capos are too narrow. Classical-specific models:
- Kyser KG6B — wider jaw for classical necks
- Shubb C3 — the classical version of the C1
- G7th Newport — classical-width
Choosing Between These Four
Need fast, reliable one-hand changes for live performance? The Kyser Quick-Change's spring-loaded mechanism is the standard for a reason — gigging musicians need speed and reliability between songs more than they need the absolute last word in tuning precision.
Recording or playing solo where pitch accuracy is critical? The Shubb C1's screw-tension mechanism lets you dial in exactly the pressure needed to fret cleanly without excess force bending strings sharp — worth the slower two-hand operation when accuracy matters more than speed.
Want the best of both — speed and accuracy — and don't mind paying for it? The G7th Performance 3's adaptive radius technology conforms to your specific fretboard curve while still offering single-hand operation — the premium choice for players who won't compromise on either factor.
Want repeatable, adjustable tension without the G7th's price? The D'Addario NS Artist's micrometer-style tension wheel lets you set and repeat correct tension across sessions — a genuinely useful middle ground between the Kyser's simplicity and the G7th's premium engineering.
Common Mistakes
Buying a standard-width capo for a classical guitar. As the classical section notes, classical necks are meaningfully wider (52mm vs 43mm nut width) than steel-string necks — a standard capo either won't fit properly or will apply uneven pressure across the wider spacing.
Leaving a capo clamped at the nut position indefinitely. As the FAQ below explains, this can leave a lasting mark on the nut over time — store the capo at the first fret or off the guitar entirely between uses rather than at position zero.
Assuming a cheap capo is a false economy not worth the risk. While premium capos (Shubb, G7th) do offer genuinely better tuning accuracy, a well-reviewed budget option like the Kyser Quick-Change is a proven, professional-grade tool at a low price — this isn't a category where spending more is always meaningfully better for every use case.
Forgetting to retune after placing the capo, especially before recording. Even premium capos cause some slight pitch shift when clamped — as the FAQ explains, always checking tuning after placement (not just before) catches this reliably, and it matters most when the recording will be scrutinized closely.
ToneStakr's Take
For most players, the Kyser Quick-Change remains the sensible default — proven by decades of professional gigging use, fast enough for mid-song changes, and accurate enough for the vast majority of playing situations. Reach for the Shubb C1 or G7th Performance 3 specifically when recording or solo performance makes tuning precision the deciding factor, not as a default upgrade.
Frequently Asked Questions
Do I need to retune after putting on a capo?
Usually yes — even the best capos cause a slight pitch shift when clamped. Always retune after placing a capo, and check again specifically before recording, when small tuning inaccuracies are more noticeable.
Will a capo damage my guitar neck?
A properly sized and correctly tensioned capo won't damage the neck. The one real risk is leaving a capo clamped at the nut (position 0) for extended periods, which can leave a lasting mark — store it at the first fret or off the guitar between uses.
What capo does Ed Sheeran use?
Ed Sheeran uses the Kyser Quick-Change on most of his acoustic performances — a notable real-world example of a professional touring musician relying on the same widely available capo recommended for most players here.
Can I use an electric guitar capo on an acoustic guitar?
Most capos work on both, with fretboard radius being the main variable to check — a capo designed for one radius can apply slightly uneven pressure on a differently curved fretboard. The Kyser Quick-Change and Shubb C1 both perform well across standard acoustic and electric radiuses.
What is a partial capo, and do I need one?
A partial or cut capo covers only some strings (typically 2-5) rather than all six, used to create open-tuning-like voicings without actually changing your tuning. It's a niche tool useful for specific fingerstyle and alternate-voicing techniques, not something most players need as a first capo.
How do I know what fret to put the capo on for a specific key?
Use the capo position guide above as a starting reference — for example, capoing at fret 5 turns open C chord shapes into F, or capoing at fret 2 turns open G shapes into A. Matching a singer's vocal range or a specific recording's key is the most common reason to reach for a particular position.
