Awhile before I started to really dig into my guitar playing- I wasn't sure if I should get one because they seemed somewhat daunting compared to my simple acoustic guitar. All of the electronic effects and what they did confused me.. I stumbled upon a website called
Expert Village: Free video clips, how to videos, and video instruction. At expert village they have many DIY type videos but found some of a man named Gary Schutt. Gary is a guitar expert and has written many different songs all by himself- every part ( If you want to see more of him, google/youtube him. talk about talent!

)
In his videos at expert village he demos and explains all the guitar effects and how they are used. and some basics of metal/shredding/advanced playing. I found his videos to be very helpful and very encouraging- they are fast,easy, and free. So for those of you that are thinking about electrics I suggest watching Gary Schutt's videos at expert village.
