If you use a capo very often, I cannot recommend Shubb more highly. They make the best capos, and they're affordable. They make a number of kinds.
Perhaps
this is the one you might need, one left at the zon, for $17.
Or the
deluxe for $24.
The main difference with deluxe is the roller instead of a plastic tip that slides in the groove. I've used both, the hard plastic tip works just fine, but the roller is nice. Note that all reviews are 5 stars.
You can see that you that the tightness is adjustable.
The only issue is that if you lose things easily, stick with the one you got (since you can just clamp it on the headstock).
Anyways . . . if you cared . . .
