The G7th Performance capo is a completely new approach to capo design. It has none of the disadvantages of conventional capos, but instead offers enhanced performance and is simple to use. Not only that, it looks and feels great!
The designer, Nick Campling, says...
I've struggled to find a capo I can live with for the best part of 30 years. They all either pulled my guitar out of tune, were fiddly to adjust, or they got in the way of my hand. Some just didn't work! The G7th Performance Capo is a result of combining my product design skills with my needs as a guitarist.
The capo is a constant source of frustration to 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 hand.
The new G7th capo has none of the problems of existing capos, but all of the benefits!
This will probably revolutionise the way we think about capos - a no hassle solution for guitarists.

Technical Info
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.
The clutch mechanism is a modified tried-and-tested design used in printers and copiers to provide a simple decoupling and overrun device.
