There aren’t many (any?) good resources online for non-tonal guitar music. Here are a couple licks with Tab. They’re fun to play and certainly useful to train fingers that are stuck in guitar-isitic patterns.
Here’s a chromatic lick involving all 12 pitch classes.
Here’s one that uses the principle of melodic expansion ( Stockhausen’s „Spreizen der Intervalle“). Note how each group of five notes expands the tessitura of the first.
This one sounds best with a clean tone, played slowly. Diads over a pedal. Always expressive.
