Featuring innovative FlexFit™ technology, the D’Addario Pro Plus Capo uses a capo arm pad designed to replicate the natural movement and pressure of a human finger when fretting a string. This adaptive design evenly distributes tension across the strings, helping to eliminate unwanted buzzing, dead notes, and tuning inconsistencies caused by uneven pressure. The result is clear, balanced, and accurate tone across all strings, achieved with minimal overall force.
