btw, I asume you also already discovered Tina Guo's YouTube channel. She also has some interesting videos about the electric cello and recording
I checked a few of her videos but she didn't seem to commit to teaching much. Like, her tutorial series has two videos from 2018 and that seemed to be it for that series. That said her approach seemed to be more anecdotal i.e. telling the audience what she does personally and how she arrived at those habits, instead of telling the audience what to do. And I think that's really useful put in relation to more pedagogy-oriented teachers. Someone else I found really good is Jonathan Humphries!
