Step 1 is setup: Saddle height, neck relief and pickup height. Start at or near factory standard, that should never sound bad.
Step 2: as others suggest find a bass amp near you, the low octaves will sound anaemic through a guitar cab.
Problem not solved? Let a bass player near you have a try on their rig, someone will identify the trouble, it's never too late to spend more money.
Now where are the pictures? 😄
