A great Jimi Hendrix intro riff using an E pentatonic scale
at the 5th fret and 7th fret positions
This riff uses pulloffs (PO) and one hammer-on (HO) - use first and third fingers throughout.
The 2 beats marked x in the tab are "dead stringing".This is where you hold your left hand on all 6 strings without pressing down on the frets to get a dead sound.
Jimi Hendrix used this technique a lot especially with wah-wah.
