I was recently learning the verse to the song aeroplane by the chili peppers, and in it, it switches from the A string to the G string quikly. At first, when I tried useing my thumb, sometimes i would accidently also hit the E string. So after quite a bit of tries I went to just trying to pop the two strings with my two main fingers. Not only do I have to slow the tempo down to do it this way, it doesn't feel comfortable. Does any one have any ideas on how to not hit the E string?
