Some thoughts
You can only adjust what is there in the first place in terms of power and tone.
A passive or active bass makes no difference, provided the tone and punch is there, a good preamp peddle should do the trick.
Abandon you attachment to the sound of yourself in isolation and focus on what it sounds like in the mix. e.g. I love the sound of a Stingray in the mix but don't like the tone when solo'd.
