I've always been a fan of the Harmonic Minor scale. It adds a cool neo-classical flavor to guitar licks and I'm a big fan of that. This is a pretty basic guitar lick that incorporates both the A minor and A Harmonic minor scales. If this is too basic for you and your a fan of this style check out almost anything by Yngwie Malmsteen he perfected this style of playing and has jaw dropping licks and some amazing compositions.
