In example number 4, we reach the end of the line. This is pretty much as far as you can go from the bridge without completely killing the string. Also, with a heavier pressure and muting, you also run the risk of raising the pitch of the string to much in relation to the rest of the music. But, once you get this really “metallic” muting down, you will be able to riff out those modern metal riffs like nobody’s business! Get to it, and meet me again in example 5 for some more exotic techniques.
