Someone else mentioned this, but take the compressor out for a bit. Based on your attack settings can definitely sap some high mids and highs. A nice preamp pedal (Mesa, subway, origin effects). Get it dialed in and then add the compressor back and see if you can get the settings matched to get the compression you want without sapping tone.
I’ve been dialing in a new bass and did this recently. Compressor was in the way of me getting the tone dialed. After I really settled in I brought the compressor back and ended up with completely different settings than I had previously.
