Well, looks like you're covered for songs in E.... :)

Hard to put together. Record it and put the result in the listening post... you'll get more of a response. For the lead bits, instead of blasting through a pentatonic scale really fast, try playing something simple and phrasing it well. It'll sound better than going through a scale.

Also, don't know if you saw the newsletter, but this scale of the month article is on Am Pentatonic. Sorry for blatantly plugging my own article - if you shift the ideas up to the 12th fret from the 5th - you're in Em... There's nothing crazy in there - but just an idea.
