Hi @mattyxxl , definitely check out the Post Your Covers discussion.
The other day I posted a practice fragments video for a song I’m learning. I have never played bass before, or any instrument (apart from a few months of being crap at guitar a long time ago). The video is 41 days after I started learning bass, and I had finished B2B but doing it all over again so I can complete all the fast workouts where possible (I couldn’t do quite a few of them when I finished B2B).
Although I cringe at my technique watching the video, I would never have thought I could make this sort of progress in such short time. I absolutely feel B2B and Josh gave me the necessary foundations to be able to go ahead and try stuff that has some tricky bits.
