Empty Walls Serj Tankian I'm writing this tab because every other tab has inaccurate parts that make a huge difference in the song. Also, this song is in drop C (CGCFAD) not drop D (DADGBe). This is used to get an octave between the open E string and the 12th fret on the E string. note: This song is played on two guitars. The only distinguishable parts of guitar 2 is during the intro, the verses, and the outro. Everywhere else, it's pretty much identical to guitar 1, or not there at all. ^ be (guitartabs.cc)
