INTRO: Guitar 1 Clean [1a)] Guitar 2 Distorted [1b)]|-----| |-----| |--9--| |--7--| |-----| Both [2)] Guitar 1 With this riff it sounds like Clint is actually using a whammy bar instead of sliding because it sounds too fluid for these notes to be played with a slide. However, it still sounds fine without, for I would only recommend the whammy if you are good with it but either way you play it make sure that you play the full bar because that fourth string is important for the sound H (guitartabs.cc)
