GC-30 SHUBB DELUXE ACOUSTIC GUITAR CAPO
It's everything the original Shubb Capo is, and more!
When the Shubb Capo was first introduced in 1980, capos were elevated to a whole new level. In 1998 the Shubb Deluxe pushed the envelope again. How could the original Shubb capo be improved?
Material:
Stainless steel resists wear and nicks. It will look as beautiful years from now as it does today.
Ergonomics:
The restyled lever is easier to handle while opening and closing.
Design:
The roller reduces wear, while adding smoothness to the opening and closing action. It engages in a track, ensuring precise alignment.
Geometry:
The closing action is more uniform, closing with the same feel and requiring less adjustment between thicker and thinner parts of the neck.
* Crafted of stainless steel, its roller mechanism provides ultimately smooth operation
* Stainless steel resists wear and nicks
* The new roller further reduces wear, while adding smoothness to the opening and closing action. The roller engages in a track, ensuring precise alignment
* The re-styled lever is easier to handle while opening and closing
* The closing action is more uniform, closing with the same feel and requiring less adjustment between thicker and thinner parts of the neck
Mechanical advantage of the Shubb Deluxe capo compared to the original Shubb Capo
The technical explanation
Shubb capos work on an "over-center" locking principle. If you've used one, you know the feeling. As you close the capo onto the neck, it passes through a point of greatest resistence (the "center"), then relaxes somewhat into its final "locked" position.
We've made up a name for the the difference between the amounts of pressure applied at these two points; we call it "dropoff."
More dropoff means a greater difference between pressure encountered as it passes through center, and the pressure applied in the locked position. Less dropoff means a lesser difference between pressure encountered as it passes through center, and the pressure applied in the locked position.
Offhand you might imagine that less dropoff is better, but that's not exactly the case. If you have too little dropoff, the lock is less secure and there is a risk of the capo opening unexpectedly. But if you have too much dropoff, too great a force is applied to the guitar neck while closing, and there could be too little pressure applied in the closed position for the truest tone.
So you see, there is a JUST RIGHT amount of dropoff that makes for perfect capoing.
