Whole note down tuning for deeper bass

Whole note down tuning is a method of tuning where all notes are tuned a full note down. It is often used when playing modern heavy rock (loud rock), where the guitarist wants to have a deeper bass sound.
Specifically, it involves taking standard guitar tuning (EADGBE [in order from string 6]) and tuning each string down one whole note (DGCFAD [in order from string 6]). Whole note down tuning can produce an even deeper bass sound for bands such as KORN that use seven-string guitars. Incidentally, Jimi Hendrix had famously played his guitar tuned one half note down. In this case, string 6 would be E♭.
