I tried to use it for classics. It is very convenient. However, a small rounding on the rubber does not allow perfect clamping of the strings on the fretboard without a rounding radius and there was a rattling.
It has a place for the pick, but you should know that there is a very thin plastic. I broke it off instantly, during the first experience of use.))) Truth is not important to me.
Otherwise, this capo is perfect for acoustics!
