Just when you thought it couldn't get more evil... 

Adjust the cascading gain stages to get the classic black metal tone or crank them to get crazy high gain riffage.

This is not just a blackened thrash machine, there are so many usable tones available with the expanded active EQ controls allow you to dial in those 'blues lawyer' tones as well as compliment your death and doom rigs.

Consider this in the category of effects where there is so much you can do, but if you just dime every control, that won't get you there. The tweaking is worth that perfect drive/distortion sound. Throw in the blend... now we can stack it.
