Lo que se suele llamar "drop C" viene a ser un drop D bajando todo un tono. Resultaría: CGCFAD
Sin embargo, en este foro Melvinófilo, hablan de una afinación similar, pero no igual a esa, en los discos de la banda:

Uno de los comentarios es bastante explicativo:
"... one thing to note is often the setlist will say CG for tuning. This means that the guitar is tuned to CGDgbe as opposed to CGCfad (which is traditional drop C).
As far as I know this is the way that Buzz tunes his guitar for all drop C songs.
And the new songs "Drunken Baby" and "Dark Brown Teeth" are definitely in this tuning.
Manky, LYSOL, AMAZON (known to be played in drop D also ie, live at belfort 2003), The Bloated Pope, Charmicarmicat (Recent live version), The Talking Horse, Evil New War God, The Water Glass, Pigs of the Roman Empire, City Dump and Graveyard (BHS) are all in CGDgbe tuning from the live footage i've found.
As far as Album material that's in a C tuning the list goes as follows, from what i can hear
Lysol: Hung Bunny Roman Bird Dog
The Maggot: all except The Green Manalishi
POTRE: all
A Senile Animal: The Talking Horse
The Bride Screamed Murder: the Water Glass, Evil New War God, I'll Finish You Off
Tres Cabrones: City Dump, American Cow
This Machine Kills Artists: Rough Democracy, Dark Brown Teeth, Laid Back Walking, Drunken Baby
... and probably more i've missed. "
En cuanto a la necesidad de cuerdas especiales, todo es probar si puedes afinar sin problemas las que tienes en tu guitarra habitual, y si no es así, hacer probaturas. Probablemente no tengas problemas bajando un tono en 4ª y 5ª, algo no demasiado raro en otras afinaciones. Bajar dos tonos en la 6ª... dependerá de qué tipo de cuerda, qué ajuste y altura de pulsación manejes, y qué guitarra tengas. Básicamente puede cerdear un poco o bastante.
