Hi Lawrence,
I have been noodling/thinking I could play for around 5 years as well, memorised the pentatonic scales, know the open and barre chords, but never felt I was progressing so started with Tomo's videos to try and find a better way to play the guitar.
I am up to lesson 12 and lesson 3 of music theory. I have deliberately been taking it slow. I do feel I am progressing, but it's been very harrd work. What has helped me and where I have been focusing has been:
Learn the notes on the fretboard. This allows me to pick a root note and play the major scale around it. It also allows me to figure out the root note in the triads, when playing a progression.
Learning the major scale, not memorising the patterns but learning the intervals. Then starting on a root note, I play the scale to the next root note. From the root note going forward, backwards and upwards/down. Then with Lesson 7, I can now solo within the key of G Major, playing and visualising notes as I move around the fretboard. May not be all musical, but it is more fluid and sounds a lot better than before.
With lesson 9 and the Bb traids, I use the major scale in the following way: Root note Bb is on the 6th fret, the triad is R, 5, 3. So because I know the major scale, I pick out the 5th, B string 6th fret, this is the second inversion of F, the 4th note is on G string 8th fret, Eb Root position. I do the same for the other positions for the Bb triads.
Make sure I can play 12 bar blues continually using the above chords, and can identify the chords when I use my looper pedal.
Next is soloing, based on triads, because I have spent time on learning the fretboard notes and the major scale, I know what the notes are, which means I try and experiment, hitting the root and 5th, then try and improvise with the other notes, major scale and penatonic scale. Again not the most musically, bu certainly sounds better.
Because I understand the major intervals, it has opened up the pentatonic scale, and understanding the intervals in that and which ones sound good(R, 3b, 5th) and which sound good when bending(4, 7b).
So in summary, while I still can't wail like clapton/gilmour, I am getting better, when I play it won't blow anyone away, but I now understand what I am playing, why it sounds good and which notes sound good.
Which brings me to another point, I really need a looper to hear what the chords sound like and which notes sound good over them.
I have also been using other teachers lessons for basics as well, to fill in gaps where I seem them in my playing. But slowly I think I am making progress.
Hope that helps.
Good luck
