Congrats on watching of all Pebber's videos, but how much you've "heard" his videos is as important as seeing them. Ok, Pebber likes to talk more than somebody could expect and people tend to fast forward the video to some actual playing, and by doing that they miss the big picture because man's talking contains exact or more amount of quality info as playing itself in those videos. Watch all of Pebber's videos again and again, every time you'll reveal something new.
Seeing scale on a fretboard is also fine, but do you see intervals of that scale on the fretboard also?
Chord making should be quite easy, if you know that it's nothing more than extracting intervals from a scale and it's modes... wich means that if main chord was made from 1st, 3rd and 5th(and 7th,and 9th etc...) interval, second chord from that scale(chord from second interval of that scale) would be from 2nd, 4th and 6th(and octave, and 10th etc...) interval of exact scale, for moving it diatonically to next step... third chord would be made from 3rd, 5th and 7th(and 11th etc...) interval from exact scale... etc. It all come down to make a chord family from "interval scales" as you call it... actually from from scale and it's modes, where you extract 1st, 3rd and 5th(and7th) interval and play them together. It's actual moving chords diatonically. Playing a chord scale based on stacking thirds. You can try to harmonize Hungarian minor this way, since you like it, why not try to make a chord scale from it.
Grabbing a nice chord should result with richness in sound, and should be pleasant for ears, and if it's not, could it be that richness in sound and clashing sound could be due to instrument qualities and specifications, amp being used, improperly tuned instrument, distortion or chorus effect if it's on, individual musical preferences etc... in my case, Hotel California intro could sound richer if I had have a 12 string guitar(which I don't have), for example...
Ok, maybe you know this already and I misunderstood you completely, and by "making chords" it might be that you're thinking of adding intervals on the chords by playing a solo over the chords. If this is the case, for start, good idea would be to work on a particular scale by extracting arpeggios from position in which you are playing that scale to learn intervals of each chord from a scale so you can easily approach that intervals while playing scale above the chord being played by band, backing track or whatever...
