Crossfire Professional Acoustic Guitar Capo (Nickel)
This easy to use CFC-7A Professional Capo is ideal for Acoustic Guitars.
The capo is most commonly used to raise the pitch of a fretted instrument so that a player can perform a piece in a certain key using different fingerings than they would use if played "open" (i.e. without a capo).
In effect, a capo uses a fret of an instrument to create a new nut at a higher note than the instrument's actual nut. No matter the style, the capo is typically placed as close to the desired fret as possible, just behind the fret. This holds the strings down behind the fret as securely as possible with the sharpest possible angle to ensure they will remain fretted.
