The first lick uses a technique calls oblique bends which involves striking two (or more) notes and then bending one of the notes while keeping the other ringing. This is often used to emulate the sound of the pedal steel. In this example, the oblique bends in bars 2 and 3 are used to create a G major (G-B-D) sound by bending the A note into a B while keeping the D note above ringing.
The second idea in this example is a very simple eighth note idea. Getting the correct sound here involves changing where you are picking. Most people tend to pick towards the middle of the body but for this example you are going to pick towards the bridge. This gets a brighter, twangy guitar sound that works very well for country guitar licks that use the low wound strings. This sound is heard on a lot of the old Bakersfield country albums (Buck Owens, Merle Haggard).
The third country guitar lick in this solo uses the same bridge picking technique as the second lick but adds open strings.
The fourth lick picks up the speed using sixths throughout. Using sixths in your soloing like this is a very common sound in country guitar playing. This lick ascends a G major scale using sixths up to C while filling the space around them with chromatic passing notes. Play the notes on the D string with your pick while using your ring finger to strike the notes on the B string.
The final lick begins with a simple descending G major scale. If this was played using only fretted notes it would not be very interesting. But when played using open notes you can get a very cool cascading effect.
