If you learn the notes to a Jimi Hendrix or Stevie Ray Vaughan solo, but your sound is still thin and weak, it’s probably because you’re not playing enough strings. Notice I didn’t say enough notes. There’s a big difference. That difference is caused by a technique called raking.
Raking is when you play multiple strings but allow only a few notes to ring out. The clicks of the muted strings accompany the notes that ring out, producing a fatter, more muscular sound that cannot be achieved any other way.
Raking is a 70-minute lesson that teaches you how to incorporate the raking technique into your playing.
