Does it work for trap and reggaeton 808s?

Yes, it is built exactly to give weight and presence to 808s and sub bass.

Can it sound muddy if I push it?

Yes. That is why it is best to boost moderately and check on several speakers.

It boosts the low range so it is more noticeable, though very small speakers will always have less sub.

When the 808 does not hit or the bass feels weak, boost it in a controlled way so it lands on speakers and headphones.
