I do understand them very well, it's just that
applying them is where so many tutorials let people down, and you're right, on the bass modes are fantastic, especially where all the shapes in say Dorian can be transfered all around the fretboard.
Many tutorials also confuse people and don't explain properly, I would explain modes like this: A mode is a major scale, starting from the corresponding note of the scale but shifted down to the root note of the major scale you are playing i.e Dorian is mode 2, so you start to play the major scale starting from note 2 of the scale on the root and emphasise that with the major chord droning underneath to understand how the mode works with the major chord you are playing in. Showing the modes in a 3 note per string pattern is an easier way to explain in a video tutorial.
I just want to be shown examples of the modes used in a song and soloing with them, your scales coupled with arpeggio tutorial in a song like So What? really opened up my eyes, especially by using all the positions all over the fretboard. It would be nice to see how to use a combination of positions on various chords, but I know you have some on your website already.
I am an experienced bass player although I still would like to see some ideas for bass lines over basic chords (chromatic runs, arpeggios, melodic forms etc), or what the power of modes can do for playing chordal formations.
So i would love to see more modal examples and how to use them please
