I just need to know how big you'd have to be (height and weight) to play a full sized electric guitar. Also, does it matter if you start playing on the electric or acoustic? Should I get a cheaper or a more high quality guitar?
What You might consider is the weight of the instrument. Ivanez is a much lighter guitar than a Les Paul(very heavy.) Electric guitars have much lighter strings and will not hurt your fingers as badly. I would actually suggest that you learn on an accoustic. , you'll build callouses quicker. Dean makes a good guitar, you may want to check out a dean Evo, or a dean Vendetta. Ivanez makes a good cheap accoustic. Here;s a web site to help you get started. http://www.chordie.com/ It has beginner songs in the public song books. Good Luck
