Standard Tuning for 8-String Guitars

Standard tuning serves as a reference point for 8-string guitarists. The most common standard tuning for an 8-string guitar is as follows:

String NumberNote
1 (highest sounding)E
2B
3G
4D
5A
6E
7B
8 (lowest sounding)F#

This tuning provides familiarity for guitarists transitioning from 6-string instruments, as the highest six strings maintain the same intervals as a standard-tuned six-string guitar. As you might already know, the basic tuning for a 7-string guitar is the same as above except without the 8th string.

Advantages of Extended Range on 8-String Guitars

Why play an 8-string guitar? The extended range of 8-string guitars opens up new possibilities for guitarists.

Examples include:
  1. Increased low-end frequencies
  2. Expanded chord voicings and harmonic options
  3. Greater versatility in modern metal and progressive music

Brands like Ibanez, ESP, and Schecter offer a wide range of 8-string models, catering to the growing demand for these instruments among experimental and avant-garde musicians.

Alternate Tunings for 8-String Guitars

While standard tuning is a great starting point, alternate tunings allow for customization to suit specific genres or playing styles. Bands that use 8-string guitars like Meshuggah and Animals as Leaders have popularized other tunings. Some popular alternate tunings for 8-string guitars include:

  • Drop E: E, B, E, A, D, G, B, E
  • Half-step down: F, Bb, Eb, Ab, Db, Gb, Bb, Eb (Meshuggah uses this)
  • Drop Eb: Eb, Bb, Eb, Ab, Db, Gb, Bb, Eb
  • Double-drop E and A: E, A, E, A, D, G, B, E (Animals as Leaders uses this)

Experimenting with alternate tunings can inspire new creative directions and help you develop unique playing techniques.

How to Tune an 8-String Guitar in Standard Tuning

Follow these steps to tune your 8-string guitar in standard tuning:

  1. Use a high-quality digital tuner like the TC Electronic PolyTune or Boss TU-3.
  2. Start by tuning the 8th string (lowest) to F#. Use a reference pitch or tune it to the 2nd fret of the 7th string. You can use the harmonic at the 12th fret to tune since some tuners have a hard time with the low string.
  3. Tune the 7th string to B, using the 5th fret of the 8th string as a reference.
  4. Continue tuning the remaining strings in the following order: 6th (E), 5th (A), 4th (D), 3rd (G), 2nd (B), and 1st (E). The 5th fret of the lower string equals the next open string except for the B string, which is the 4th fret on the G.
  5. Double-check your tuning by playing chords and comparing octaves.

If you encounter tuning instability, consider using thicker string gauges or adjusting your guitar’s setup.
