I find most of the Bass Real Tracks are muddy and need significant EQ (and other effects).
The first thing that comes to my mind is
How are you monitoring?Otherwise, like the others, I find that some styles need more love and attention on the bottom end than others. I like Bud's suggestion of using amp sims, too.
As a pro bassist growing up in the '60s–'70s, I often like my bass on what others consider the dark side. I don't do "in your face" bass.
Gibson basses with the huge "mudbucker" pickup... Can't believe I owned 3 of those over the years but all got DiMarzio Model One replacements to get some midrange into the sound. All were sold 20 years before the stroke that crippled my left arm 14 years ago. It's hard to believe those are now worth some serious coin and Gibson is making them again.
