10 Best 12 String Capos 2026 in the United States

The D'Addario NS Capo is a solid choice for guitarists looking for a reliable capo for their 6-string or 12-string guitars. One of its standout features is the micrometer tension adjustment, which allows users to fine-tune the pressure on the strings. This means you'll achieve a buzz-free sound no matter where you place it on the fretboard, which is especially beneficial for those who play in various tunings or styles. The adjustable tension combined with its strong, aircraft-grade aluminum construction ensures durability and longevity.

Ease of use is another strong point; the capo is designed for quick adjustments with a single hand. This feature is ideal for performers who need to switch keys on the fly during a performance. The lightweight nature of the capo (only 0.3 grams) means it won't weigh down your guitar or affect your playing.

While the capo is versatile, fitting both acoustic and electric guitars with radiused fretboards, it may struggle with very thick necks or unusually shaped instruments. Additionally, some users might find that the adjustment screw, while effective, can be a bit tricky to set up initially if they're not accustomed to using a micrometer system.

The G7th Heritage Guitar Capo with Wide String Spacing is designed especially for guitars with wider necks, making it a good fit for 12-string players or those with a nut width over 46mm. Its traditional yoke style is low profile, allowing it to be comfortably stored behind the nut when not in use. One of its standout features is the adaptive radius technology in the silicone string pad, which adjusts to the curve of your guitar’s neck. This helps maintain tuning stability by evenly pressing down all the strings without causing buzz or tuning issues.

The capo also uses inert silicone rubber to protect your guitar’s neck from metal contact, reducing the risk of scratches or damage. Made from durable materials like stainless steel and nylon, it feels sturdy yet lightweight (about 1.9 ounces), which adds to ease of use. The tension mechanism is carefully designed to apply the right pressure—firm enough to hold strings down, but not so tight as to affect playability or tuning negatively.

It is mainly intended for wider neck guitars; it may not fit or work as well on standard or narrower necks. This capo is well suited for 12-string guitarists or anyone needing a wide-fit capo that offers reliable tuning stability and neck protection without complicated adjustments.

The G7th Newport Guitar Capo (C32013) is specifically tailored for 12-string acoustic guitars. Made from silver, this capo is designed to fit snugly behind the fret, ensuring a secure grip without excessive tension that could damage the guitar. One of its standout features is the longer arm, which is ideal for the wider fingerboards found on 12-string guitars. This ensures that all strings are pressed down evenly, resulting in clear and consistent sound quality.

The capo's tension can be easily adjusted, which allows for precise control to avoid buzzing or muting of the strings. Additionally, the padding on the capo helps to protect the guitar's neck from scratches or wear over time. At 2.08 ounces, it is lightweight and won't significantly add to the guitar's weight, making it convenient for both practice and performance.

However, it is important to note that some users have mentioned difficulty in quickly navigating the capo during live performances due to its design. While the majority of users appreciate its secure fit and ease of use, a few have found the adjustment mechanism to be a bit fiddly compared to other capos. The G7th Newport Guitar Capo is a solid choice for 12-string guitar players looking for a capo that offers both enhanced performance and protection for their instrument.
