String choice , your decision , flats or rounds is going to colour your tone the most. And then every link in your signal chain will have an impact. Your bass choice , amp selection , cab preference. And no two rooms sound the same , and the number of people around will change the sound of the room throughout the night.
Everything matters.
I usually play mid sized bars. Much of the time I’m not in the PA. I’m looking for a rich , deep , thick , old school thump , but not boomy. Flats , mostly using a med scale hollow body bass. Tube preamp , class D back end and Berg cabs. I’ve found the tube preamp makes a big difference. I’m in the house band that does a weekly jam , the thumpers tell me the rig is magic. The hifi ones tell me it’s old school. I tell them it’s exactly what I’m after.
It’s surprising how it sounds completely different depending on the player.
