This is our favorite capo here at Guitar Works, Inc. Its fast, not too big, can be clamped on the headstock when not in use, is affordable and being able to dial in the exact amount of presure you need is a must. So many of the other grip style capos give you either too much clamping presure or not enough with no way to adjust them. Here is the manufacturer’s description: The Planet Waves (A Division of D’addario) Dual- Action Capo for 6 string acoustic and electric guitars. The product of an ongoing collaboration between famed product designer Ned Steinberger and D'Addario. The compound action reduces the force necessary to open and close the capo. It also eliminates side-pulling the strings out of tune, which is prevalent on other trigger- type capos. Aircraft-quality aluminum construction adds virtually no weight to the guitar's neck when in use and the capo can be clamped on the headstock when idle. Simply adjust the tactile micrometer tension control so there is just enough tension to eliminate string buzzing. We sell about a dozen different capos here in the store.
