Welcome @TOTAL!
I think @Octagonist gave you the best answer here, probably not wise to trust the AR’s compressor as a safety net for volume. That said, the compressor does sound really good and it is plenty versatile to treat as a sound design tool, so that’s how I’ve enjoyed using it most.
It’s especially nice to tweak the compressor in combination with the master distortion, you can draw out some really nice flavor by playing with the balance between the two (or completely obliterate your sound into something new and interesting).
