whenever i bend my fingers get caught on the strings above and make an unpleasent and unwannted sound what do i do??
Common Problem it is(i think. it was for me). Just keep practicing and you won't even notice that you're not doing it anymore
try to use your left over fingers to mute the string your not using. I use you have this problem its just something you have to work out.
^Try that method, muting with your fretting hand, or try muting with your picking hand palm whenever you move in for a bend.
I usually try to bend with my fingers at a perfect 90 degree angle to the fretboard so that the other strings hit my upper fingernail, which usually keeps other strings from ringing for me.
