Hey there!

I love to jam on blues backing tracks, like ZZ Top's La Grange or Jimi Hendrix Purple Haze, but all I use is the pentatonic blues scale. I know it all over the fret board. I also know some techniques like bending, vibrato, and pinch harmonics and stuff, but my solos are getting repetitive.

My question: how can I spice up a blues solo? Are there other good scales to use? Or some nice tricks?

Everything is appreciated.
