Bassboost

[Aggon98]

This bot is amazing and it even contains the premium features that other music bots want us to pay for.
The missing feature however for me is:

---> !Bassboost on/off

Or with a little complexity:
---> !Bassboost 1-100

I'd love to see something like that. Could it be possible?
