I‘m a big fan of Josh Fosleys videos, he makes great tutorials without pushing his program too much, although I heard a lot of great things about it. Any bass player should learn how to set up their instrument not just to save money (we all know how expensive strings are, lol) but also to learn what kind of setup you desire.
Are you more on the low action side or do you prefer higher action?
This was a really useful post by Josh - who really is a great teacher by the way. Seeing the actual results and the way that the two basses actually compare was informative. With regards to your final question, for me it’s action slightly on the low side.
