Hey, you should check out Josh Fossgreen - He is THE best online instructor thus far.
SBL - NOPE… takes far too long to get to any point. I did the free trial once and saw his youtube vids - unless you have hours and hours to sit and watch videos with your bass on your lap doing nothing - then a 5 minute playing lesson, then listen to him for another 12 minutes - nope - i aint got time for that BS. I am sure he is a wealth of knowledge, but the focus is not for the player to learn ‘quickly’ - its to keep subbing for another year and another year etc etc IMO
FBPO (for bass players only) Jon Leibman is a good choice - I sub to his stuff as well - he gets to the playing FAST…maybe a smidge too fast - but hey, if i want to ‘get er done’ - he is a good choice. He has a soft demeanor while teaching and his site is easy to navigate.
Another one that is VERY good - but pricey…is TMBG (teach me bass guitar) The instructor is a tad monotone and it leans towards the blues/country styles - but it is incredibly well thought out on screen - finger placements etc.
That’s all i got
*I am still struggling with my recent broken hand(twice) - now dexterity is garbage - so, i have to be patient…i am NOT good at that apparently.
