I don't know the make but what I use is a black plastic capo that hooks on to the guitar and loosens when you push the lever toward you and tightens when you push the lever away from you. There is no name on the capo so I don't know what it is or when I got it. Maybe some of you might be familiar with it but it holds the strings down well and when I loosen it, I don't have to take it off of the guitar. I just slide it over the nut.
