This book does not cover the core techniques of playing guitar, but it does have some useful tricks you can use to spice up your playing like right-hand tapping techniques, hammer-ons and pull-offs, lots of whammy bar tricks, volume swells, rakes, muting, harmonics, and more cool stuff. It's not Stetina's best work, but it's definitely worth buying for the guitar player looking to spice up his playing. I reccommend it for Intermediate to Advanced players.
