Here's a wicked little lick that weaves through a F#m7b5-B7-Em9 chord progression.
This exotic chord progression brings a gypsy-jazz tonality to mind, especially if you use a half-step bend into the F# in the second bar, instead of sliding into it.

I performed this lick with the slide, which has more of a rock sound, but if you want that Django-vibe, bend an F (10th fret/G string) into the F# and you'll be escorted away to France (circa 1939).
Give this lick a few laps and let me know what happens.
