Overlooked and underrated YT sources

A bass educator that I feel is overlooked, and one that I used extensively when first learning back in 2020 is Andrew Pouska/Study Bass. Not neccessarily a YT'er although he does have a channel. His website, studybass.com is full of organized lessons especially for beginner through intermediate players. Most of it free although I was a supporter while going through the complete course. I learn as much by reading as I do by seeing and doing and much of the course is reading material. I still go back to review things from time to time.
 
I don't know if you can call him overlooked because he just hit 100K subscribers, but Dan Hawkins' Online Bass Lessons have been amazing for me. I usually only see BassBuzz or Scott's Bass Lessons mentioned, but Dan has tons of free videos on his YT that are so full of information with little to no filler whatsoever. I'll watch other bass videos to be entertained, but when I want to seriously learn I go to Dan Hawkins' YT or courses.
