I have a spring-action grip style capo that is designed for changing the position easily. It used to be great, however now I am finding that quite often it will not fret some of the strings properly, which results in buzzing or in some cases muting the strings completely, especially when using it at the lower frets.
I have had the capo for about a year. I am guessing that this is probably expected with this type of capo, but I thought it was worth asking before I went out to buy a new one.
Within the context of this question, it might be useful if anyone had any tips or hints for helping to prevent this with the next capo I get.
