Here’s some info from G7th
In 2004, The Performance Original set a new standard in capo design.
Players loved the way that it kept the guitar in tune, but wanted it to be smaller and lighter, without compromising the tone.
All that has been impossible until now:
The new Performance 2 gives you the ultimate capo experience.
Not only have we made it slimmer and lighter, but we have also reversed it’s patented clutch mechanism, which gives it a lightning fast squeeze-on, squeeze-off action. It has also been designed to store behind the nut or on the peghead when not in use.
