It depends on the tune & player. But even when you see a guitarists moving all over the fretboard they can still use the same scale.

Any given diatonic scale only has 7 notes (or 5 for pentatonic scales) that repeat over & again & can be played as low or high as the intsrument allows in lower or higher octaves of the same scale.

This tutorial shows how you can cover the fretboard with one scale (A diatonic major).

This one shows how you can cover the fretboard with A major pentatonic.
