Kyser KG12B Quick-Change 12-String Capo (Black)

I use it with my seven-strings guitars and it works fine.

Make sure you get the correct Capo for the type of guitar you are playing. I have 4 different types of Kyser capo's and they are all excellent

This capo will do the job, but beware, it can be dangerous and a bit annoying.

Im used to the dunlop capo and prefer this compared to the capodaster, but thats just a personal taste.

I couldnt find a dunlop for 12 string so i had to go for this, but i prefer the capo to be behind the guitar neck rather than over it. Also the dunlop is easier to attach to the guitar neck
