Remember one of the earlier segments I mention "tweaking the third" of your chord? Well, here we go again :-) This groove has a lot going on, so we'll break it up into sections to make it easier to learn. The intro is actually fairly difficult to get it to groove properly, so I recommend slowing it down and using a metronome to keep consistent time going so you never lose the tempo. We're playing the intro unaccompanied, or maybe just with the hi-hat playing time, so it's essential that we're playing in time right off the top. The main riff is very familiar, drawing upon Lightnin' Hopkins style guitar playing and can be repurposed in many blues tunes so please take note!
The tempo I play at when showing it to you is a lot slower, but I think it sounds just as cool. The tricky spot (well, the whole thing is actually tricky) comes where I believe Jimi bends behind the nut to once again, "tweak the third." I can't be sure that this was what he was doing, but on some recordings it sure sounds like it. If it's not, well it sure does look and sound cool, doesn't it?
