Here's the newest Banjo Capo on the market. These capos were designed in England for guitar but they just been released the new banjo model.

The G7th Performance Capo is a completely new approach to capo design. Using a patented wrap-spring clutch mechanism, it has none of the disadvantages of conventional capos, but instead offers enhanced performance and is simple to use. Just tighten and squeeze it on the neck. To release it, just hit the little lever. Not only that, it looks and feels great! It's quick to put on and causes minimal need for retuning.

It will fit banjos, bouzoukis, and mandolin family instruments with flat fingerboards. It's the newest addition to the G7th family.
