I honestly dont know anything about changing the different knobs to get just what sound i want on an amp, so i need help here x.x. I play a Jackson RR JS, and my amp is a Drive CD300R ( i dont really love it but i gotta steal =D). I'm looking for that real powerful low metal tone, similar to bands like Bullet for my Valentine, Black Tide or All That Remains.

There's an ultimate settings thread stickied at the top of the forum.
I don't give a shit if you listen to me or not
please make sure to read the first post of the ultimate settings thread, it talks about EQing. then the next few posts have places where you cant start to find certain tones.
