| The G7th is an innovation - a completely new approach to capo design.
It can be operated by one hand, and because of its novel design, is adjustable at the same time. Pressing down
on the capo arm locks it in place. The force on the strings depends only on how much force you use to secure it,
adjusting easily to different string gauges and playing actions.
"This will probably revolutionise the way we think about capos - a no hassle solution for guitarists." --- Guitarist Magazine Nov 03 |

THE CAPO PROBLEM:
The capo is a constant source of frustration to many guitarists. They can be awkward to use. They can pull your guitar out of tune. They can interfere with the players hand. Most capos fall into 2 categories: Non-Adjustable - These capos usually work using a strong spring. They are simple and quick to use, but the spring tension cannot be adjusted, therefore they exert a different tension on each fret, and often cause tuning problems. They can also require a lot of strength to use. Adjustable - A good adjustable capo is less likely to cause tuning problems. However many are awkward or fiddly to use. Some have only stepped adjustment which is too crude. Others interfere with the players The new G7th capo has none of the problems of existing capos, but all of the benefits! |

TECHNICAL INFORMATION: The wrap spring clutch consists of just three elements: a fixed hub, a moving hub, and a spring whose inside diameter is just slightly smaller than the outside diameter of the two hubs. When the spring is forced over the two hubs, attempting to rotate in the direction which opens the capo wraps it down tightly on the hubs, positively engaging them. 
Rotation in the other direction, to tighten the capo onto the strings, is not restricted. To release the capo,
the control tang is moved in the direction to unwind the spring, thus releasing the clutch.
The beauty of this type of clutch for this application is that it can be adjusted in tiny increments. Patented Performance Capo Mechanism. US Patent 6635813. UK Patent 2361089. Patents pending in other countries. The clutch mechanism is a modified tried-and-tested design used in printers and copiers to provide a simple decoupling and overrun device. Push the lever to release the arms. Fit snugly behind the fret. Squeeze to tighten from above or below. Press lever to release Store when not in use. |
