Kyser KPA Pro/Am Steel String Guitar Capo

The Kyser Pro/Am Capo is designed to help you change keys quickly onstage.

Position the Kyser Quick-Change as close as possible to the fret to be clamped. The Kyser Quick-Change is designed to  eliminate interference with the fretboard playing  hand. To accomplish this, position the Kyser Quick-Change such that the string spanning  clamping jaws do not protrude past the lower edge of the fretboard.
The Kyser Quick-Change should not remain  clamped on the guitar strings when not in use.  Removing the Kyser Quick-Change from the  guitar allows the rubber strip to restore  itself to its original shape.
Always unclamp the Kyser Quick-Change to move it. Do not slide it up and down the fretboard.
Periodically, oil the pivot and the spring contact  points.
