I am no fan of scales personally. I find them boring as all get out. Which is why I haven't made any vids of those
When I hit a plateau, I usually do the following:
1. Make a backing track w/ some random chords and see what comes out 2. Record a fun little chord progression on my looper and play over it 3. Put on a CD I haven't listened to in a while and play along 4. Turn on the TV, turn off the sound, play along
This seems to have helped me get out of those ruts, and I have found some cool riffs that way.
