Why it sounds like that

The intro to Chop Suey! layers acoustic guitar with twin electric leads, then lurches into a thick wall of distortion. The album's guitar sound was built from stacked tracks: a muddy guitar over a rock guitar over a heavy metal guitar, each one played again and again until it was right. The amp sound came from Marshall and Mesa Boogie cabinets and heads, with the Mesa giving the bite and the Marshall the body. Together they make a big, full sound. Malakian doesn't like to play through effects pedals, so his tracks were recorded fairly straight.
- Layer an acoustic guitar under twin electric leads for the intro.
- Stack a muddy guitar, a rock guitar and a heavy metal guitar, one over another.
