I agree with the pentatonics aenwsr. This is a great starting point for all solo lead guitar work. Plus, it's movable up and down the neck, so you can adjust it for different keys. Here's a quick little example: Play the 4th string at the 5th fret, then the 7th fret. Next play the 3rd string at the 5th and then 7th frets. Now lower all this 3 frets . Play the 4th string at the 2nd fret, then the 4th fret. And play the 3rd string at the 2nd fret, then the 4th fret. ( You should use your first and third fingers for this) In both examples, you're are playing in the key of A, but the first example sounds more rock and roll, while the 2nd example sounds mellowier, or country-ish. Your playing the same lick in both examples, but they sound completely different, yet, again, both are in the key of A. This is pentatonics learn this scale and your solos will improve plus, I recommend some instrumental rock, like the Ventures a great starting point for all lead guitar work. Lastly, remember! You have to be a good rhythm player before you can ever be a good lead player. Most youngsters neglect rhythm guitar because they want to get their rocks off and be the next Clapton or VanHalen or Satriani..or whatever. Good solid rhtyhm guitar work is the basis for great solos.
