Korn and Fear Factory (since Obsolete) also uses the Standard A tuning, but on a 7-string (A-D-G-C-F-A-D)G/A tuning - G-C-F-B-D-G / A-D-G-B-E-AFour full steps down from standard tuning. Utilized by Cannibal Corpse on some songs. Used by death/doom metal band Encoffination. Also used by Mark Tremonti on the song "In the Deep" (Myles Kennedy uses a 6-string guitar tuned to Drop Db in the song).G tuning - G-C-F-A-D-G / G-C-F-B-D-GFour and a half steps down from standard tuning. Used by the Doom Metal band Warhorse and the Brutal Death Metal band Mortician and the Sludge Metal project Foreigns.F/G tuning - F-B-E-A-C-F / G-B-E-A-D-GFive full steps from standard tuning. Used by the Death Metal band Disfiguring the Goddess.F tuning - F-A-D-G-C-F / F-B-E-A-C-FFive and one half steps down from standard tuning. Used by the deathgrind band Maruta, the instrumental doom metal band Bongripper, and the progressive metal band Meshuggah (however the band uses eight-stringed guitars).Octave Tuning - E-A-D-G-B-ESix full steps (one octave) down from standard tuning. The Low E has the same fundamental frequency as a bass guitar, essentially the same standard tuning as a bass guitar but with a high B and E added to mimic a regular guitar. This tuning is used on the Fender Bass VI and similar instruments. Notably used by John Lennon and George Harrison with The Beatles, Robert Smith of The Cure, Jack Bruce of Cream, and Deftones bassist Sergio Vega on their album Gore. In his early days with Ronnie Hawkins, future Band bassist Rick Danko was also seen with a Fender Bass VI. This is the tuning Earth used on their seminal drone doom album, Earth 2. Also used in some Doom Metal and Sludge Metal bands such as Wetlands and Thou. Raised From standard EADGBE, all the strings are tuned up by the same interval. String tension will be higher. Typically requires thinner gauge strings, particularly the first string which could be as thin as six thousandths of an inch (about the thickness of a single human hair). A capo is typically preferred over these tunings, as they do not increase neck strain, etc. The advantage of these tunings is that they allow an extended upper note range versus a capo used with standard tuning which limits the number of notes that can be played; in some cases, instruo B or E (such as saxophones, which were frequently encountered in early rock
