About 8-string Tuning

The 8-string guitar adds both a low B and a low F# string (F#-B-E-A-D-G-B-E), pushing the instrument's range almost into bass guitar territory. This massive tonal range has become the weapon of choice for djent, progressive metal, and experimental composers who need bone-crushing low-end and soaring highs in a single instrument.

With artists like Tosin Abasi, Meshuggah, and After the Burial leading the charge, the 8-string guitar has redefined what's possible in modern heavy music. The low F# string delivers subsonic heaviness that you can feel in your chest, while the upper strings maintain standard guitar voicings for leads and clean passages. Extended-range compositions often exploit the full span of the instrument, creating a wall of sound that covers bass, rhythm, and lead guitar roles simultaneously.

Notable artists: Meshuggah, Animals as Leaders, After the Burial, Intervals, Monuments

Best for: Djent polyrhythms, extended-range metal riffs, experimental compositions, and one-instrument arrangements spanning bass to lead
