A little bit of whammy bar from the strat in our guitar lick. Breaking out the strat also means the guitar lick is played tuned down a half step. I hear this lick in C Lydian but it does tend to emphasize the D note so you may interpret this as the D Mixolydian Mode. In either case it is derived from notes of the G Major scale which are all natural with the exception of the F# note. I use the whammy bar on the strat between the slide from the D note to F#. You can practice using the bar in multiple places with the legato in this lick to try and create some different phrases and feels.
