Hey RockerDCR, there are many songs that have a really hard sounding guitar part but in reality are quite easy. A prime example of this would be the song Thunderstruck by AC/DC it is just a series of pull off's throughout the whole song. Anyone that i play that song for is quite impressed. There are lots of other tricks that make a cool sound on the guitar such as basic tapping or pinch harmonics although they take some practice the result is definetely worth it. Peace.
