Yes. Although the main difference between this one and the Kyser 6-string capo is a slightly tighter spring to hold everything in place.
Would my Kyser 6-string capo do just as good a job?
In hindsight I would not advise rushing out to get this capo unless the ones you already had didn't fit your 12-string guitar?
Can it work on my 6-string guitar?
If you're feeling lazy you can transfer this capo from your 12-string to your 6-string without any cause for concern. The only thing I would make you aware of is that the spring is tighter than the Kyser 6-string capo and therefore might cause tuning issues on 6-string guitars with lighter gauge strings.
