yes, I agree with what you said. As it stands right now, as I type this, I think I might be leaning towards some new pick ups, and possibly an active EQ to breathe some new life into it. That’s probably the biggest complaint that I have. It just sounds very thin.
Been doing some research and I’m kind of confused on the pick ups and the active EQ. I found some EMG‘s and some DeMarzios but I’m not sure what else I need to get in addition to that.
I see something like this, but I’m not really sure if this is what I need if in fact, I want to switch pick ups and do an active EQ instead of selling the guitar.

Yeah, it is quite the
"rabbit hole" we're asking you to jump down. There are so many choices that picking
"The One" can be difficult, at best. However, there is a checklist you can follow first;
1.
Built-in adjustments. Lower your strings to just above buzzing or whatever is comfortable to you.
"Different strokes" and all that. After that, measure where your pickups are, relative to the body and strings. See if raising your pickups a millimeter or two helps a little. If that's too boomy or distorted, bring them back down.
2.
Strings. Once you have your bass dialed in to the best you can get, assuming it's not already there, strings would be the next step. I, for one, have gotten many different tones out of the same bass by trying different types. If you're using nickel-plated steel
(aka: "NPS", to some), you may want to try some kind of flatwound strings.
To cite a couple of examples, I've found .100-gauge D'Addario Chromes and Ernie Ball Cobalt Flats to have a nice mix of warmth and brightness, especially when coupled with my more
"diggin' in deep" style of playing. The former did amazing things to the volume and deeper EQ of a Fender-Japan Jazz bass and the latter saved a very aggressive Fender Blacktop Jazz by balancing out the
"punch" and
"grind". Your personal mileage may vary, though.
3.
Series/Parallel Switch. This is a cool mod. All it takes is a 250k push-pull pot, the right wires and someone skillful enough to install it. I've had it it done to more than a few basses and turning both pickups into a single, throatier and punchier pickup is a welcome addition.
4.
Pickups. Now, we're
really getting into the weeds! I, for one, have fallen back on several YouTube demos to give me an idea of which direction to go, as well as some TalkBass advice. But, you never truly know what you're gonna get until you've installed them. For example, I'd seen tons of positive feedback regarding Fender Pure Vintage '74 pickups, but I found them to be
"just okay", but that's just my case out of several...go fig!
As for DiMarzio pups, like many, other manufacturers, which ones have
"that sound" you desire in your head can be tricky. Fortunately, some of their popular models aren't ferociously expensive. For example, the DP123 Model J's are frequent go-to pickups, are about $150 brand-new and have the advantage of having adjustable pole-pieces to really dial in one's preferences.

"THICK"!
Full disclosure...I, myself, haven't had a chance to try DiMarzio pickups, but if I ever do, I'd check the TB Classifieds for a used pair, first. What I have utilized, and like very much, are Bartolini
"Classic" pickups. I have two different models, a P/J set and a singular soapbar, on a couple of basses. I definitely prefer them to Bart's
"Original" pups. Again...deep and thick, but your mileage may vary.
