My two cents on the thread:
Josh Fossgreen - Best teacher to go from a dead stop to bass competency. Literally Beginner to BadAss. If not for him, I’d never even tried to play bass. I can’t overstate this. He made me feel like I could really do this. He’s tops.
Mark Smith - He’s excellent too. Love his “lectures.” He’s a stand up guy; helped me realtime when I had login problems. I look at him as the best intermediate teach, although Josh’s original channel does too.
Those two are my main teachers.
Honorable mentions:
Greg Hagger - Intermediate, but a different take and I like his videos. He’s got a music reading course too.
Luke McIntosh - He’s a good supplement too. He’'ll sing a bit, and and that helps with some lessons. A little more ear emphasis.
I have no use for Scott. He does not inspire me at all.
However, at the end of day, if I had just one-- it would be Josh.
