I'm really having problems with the solos on kill em all and I was wondering whats some good solos to begin with like Heavy or thrash metal stuff.

Start with "Nothing Else Matters"

Black Sabbath - Paranoid.

It's really fun to play, not too difficult.

ya i know paranoid solo that is the first song i learned on guitar. Ill try nothing else matters one, anyone suggest some shit?

I Know its not metal, but the blues great for building speed, dexterity and vibrato for begginers.

go learn the Pentatonic and Blues Pentatonic. and just start slow, tapping your footto good blues rythmn, and make it up from there (staying in the scale).

also Pentatonic scales are used a bunch in metal. More Old school, and Trad Metal.

Happy soloing!!
