There are 25 bass presets in .SerumPreset format, no filler stuff. Just different types of low-end you actually reach for when building a track.

Some hit like a clean 808 you don’t have to babysit. Some are rougher, more aggressive, good when the track needs attitude. A few have movement in them, the kind that keeps a loop from sounding dead after 8 bars.
You’ll see names like Smack, Metallic Reese, Super Dubstepper, Bass Deeper, Walker Harsh… they’re not there to sound fancy, they just describe how they behave when you play them.

If you’re making trap, drill, hip hop or RnB, you’ll probably use most of them.
If you’re into house or tech house, there are patches that sit nicely without taking over the groove.
Push them harder and they still hold up in dubstep or drum and bass without falling apart.
