This bass guitar lesson is something of a monster...
The video lesson weighs in at just under half an hour and I honestly could have gone on for hours more. That's how many ideas you get for bass lines, solos, and fills when you know only a handful of core concepts.

Mode, Triad, Arpeggio, Scale Shapes For Bass Guitar
I have loads of free lessons that go into the specifics taught in this one. If you need to brush up on your triads, arpeggios, modes, or technique, search for that on my site or YouTube channel.
Or consider my comprehensive From Beginner To Bassist course. It contains 80 video lessons going from the very basics to improvising, music theory, ear training, and reading charts. There's probably a good year's worth of serious value in that course.
