Learning how to adjust the bass regarding intonation, string height, pickup height, neck bow ( truss rod ) etc is a valuable skill to get a poor or mediocre instrument play nicely to how you wish it to be.
I learnt many years ago as a guitarist and everything from fitting strings correctly to action is a very important thing to learn.
My test on my bass is if I can play Iron Maiden gallops finger style on the E and A strings without clatter etc I’m set where I like it !!
