Guitar amp sounds and buttons?

Hey I'm a beginning electric guitarist (2 lessons so far :D) and I paired an Adam Levine 222 First Act electric guitar with an Ibanez IBZ10G amplifier. If I play the electric guitar without the amp it sounds acoustic. If I do it with the amp it STILL sounds acoustic. What knob do I mess with on my amp to make it sound like a rock guitar somewhat sounding like My Chemical Romance's song "Dead!" The guitar sounds almost like thunder. On the amp I have gain,treble,bass,middle, and an off and on switch,but there's ANOTHER small button that says off/on. Any help?? Thanks
