Here are some basic lessons you
can use to start your guitar career.
Hammer-on Pull-off lesson
Play this over and over until you are good at
hammer-on's and pull-off's
Palm Muting
lesson
Use this part of
your hand and practice finding the right spot to palm mute by strumming
all the strings and listening for when it is only slightly muted.
Be sure not to completely mute the strings.
This is the only other cool
site I could find that had lessons.
