So I've noticed that when I bend a string that my ring finger, I don't believe my index has this problem, anyways, when I go to bend the B string or say a G my finger gets caught under whichever string is lower and it muzzles, makes a weird vibrating noise instead of muting. Now your probably suppose to mute the lower string right and just hear the higher one, right? I have no idea since I don't really bend but is there any way around this problem?
It also sounds like your action is a bit high (from what you said about the bending fingers going under the lower strings).
