E|------| B|--6---| G|--9---| D|------| A|------| E|------|From this finger position, you can play up and down the fret board and it will be a raunchy chord. As you can see, raunchy chords are very simply to play. You can also play lower octave raunchy chords. To do so, pick yourself a note on any given string on the lower (pitch) chords and find it's 1/2 step counter part on any other string. Here is an example using the A and the G chords:
E|-----| B|-----| G|--10-| D|--X--| A|--9--| E|-----|Notice the mute on the D chord, this is because it does not fall in the definition of a raunchy chord as described above. The closest note that would be "acceptable" would be the fourth (4th), fourteenth (14th), and fifteenth (15th) fret on the D string. By muting this note, we play our two notes that are a 1/2 step from being an octave in a lower pitch as opposed to the higher pitch example earlier. Something you may or may not have noticed is that in the two example I give, the two (2) notes are a half step DOWN from being an octave, this is not required. You can certainly play a raunchy chord with the two (2) notes being a half step UP from being an octave, it is just own of personal preference and in my opinion, simplicity that I play my raunchy chords a half step down from being an octave. In conclusion you should have a basic understanding of what a raunchy chord is, what purpose they serve in a song, and most importantly how to play one. Now go out and serve up some brutal breakdowns!
