Dunlop 83CD Curverd Trigger Capo

I bought the Dunlop capo as it looked to be neater than the Kayser capo. This was the model for 12-string guitar. I have used several Kayser 12-string capos without any difficulty, but the Dunlop capo doesn't clamp down strong enough on some of the paired strings that have octive strings of a different diameter(Namely the D,A, and G strings), so I get a buzz or an unclear sound. In addition the use of this capo requires much more hand pressure than the Kayser. If you want a quick change capo...get a Kayser.
