ok dude not sure if this is a korn/staind sound cause i personally think they both suck but i have my metalzone set up really kick ass lots of my friends like to copy my sound but i have it like this:

bass: all the way up
treble: 3 o'clock
mid: off
mid freq: 1 o'clock and on your have bass at 8 mid off treble on 6 its a pretty heavy kick ass sound u should like it
