I assuming you're tried sequences too? Playing through the scales with repeating patterns?
So the notes played for the "threes" below, in the C major scale would be: C D E, D E F, E F G, etc.
The most common are:
"threes" - 1 2 3, 2 3 4, 3 4 5, etc.
"fours" - 1 2 3 4, 2 3 4 5, 3 4 5 6, etc.
"thirds" - 1 3, 2 4, 3 5, etc.
But of course you can keep it going up to fives, sixes, sevens, eights and forths, fifths, sixths, sevenths, octaves.
Another nice thing to do is quasi-arps, like:
"quasi-triads" - 1 3 5, 2 4 6, 3 5 7, etc.
"quasi-7ths" - 1 3 5 7, 2 4 6 8, 3 5 7 8, etc.
Do them all up and down.
One last thing I like to do is take the "thirds" and "quasi-triads" and precede them with a chromatic approach from 1 fret below. Remember, it is a chromatic step
below even when coming down the scale.
And lastly, mix up the rhythms. Start the sequence off the beat. Or do a 4 notes sequence as triplets, shifting the accent around. Do a 3 note sequence as 16th notes. Mix it up.
That should keep you busy for a few years.
Peace,
