How Do I Make My Guitar Sound Electric?

Hi Andrew, or Mr.Cockburn, my name is matt and i have been using your beginner guitar videos. They are really in depth and i have been learning a lot so far. I just got my guitar this past weekend and i had no idea where to start but thanks to your videos i feel like i can eventually make it to being a great guitarist. But one thing i would like to know is how to make my guitar sound electric. I have an epiphone special sg model. It came in a starter kit with a 10 wat amp. I have 5 knobs on my amp gain,volume,treble,middle and bass. I have messed around with them a little bit but my guitar doesn't sound electric. It just sounds like an amplified acoustic guitar. I was looking at your lesson on how to play smoke on the water and the notes sounds so electricy, haha I don't know how to explain that better. If you could give me some tips on how to set the knobs to create a ore electric sound it would be greatly appreciated.
