A 7-string guitar adds one additional string — typically a low B — below the standard six-string range. This gives players access to extended low-register riffing without sacrificing standard guitar tuning and technique on the remaining six strings.
The 7-string guitar entered mainstream guitar culture in the late 1980s, popularized significantly by Steve Vai’s collaboration with Ibanez on the Universe model. It found its true cultural home in the 1990s and 2000s with nu-metal and progressive metal bands — Korn, Limp Bizkit, Periphery, Dream Theater — who used the extended range for heavier, lower riffing while retaining the ability to play standard guitar parts on the upper six strings.
Unlike a baritone guitar (which transposes the entire instrument lower), a 7-string keeps the top six strings in standard EADGBE tuning and adds a seventh string, typically tuned to B, below the low E. This gives you both worlds from one instrument.
How a 7-String Works
The standard 7-string tuning is B E A D G B E — read low to high, a low B string sits below the standard six strings, which remain in conventional EADGBE tuning. This means every chord shape, scale pattern, and technique you already know on a standard guitar works identically on the top six strings of a 7-string. The seventh string is simply additional range you can incorporate when you want lower notes.
This design choice — preserving standard tuning rather than transposing everything — is what distinguishes a 7-string from a baritone. A baritone requires relearning your reference points for where notes sit, since everything is shifted. A 7-string requires no relearning; you simply have an additional, lower string available.
What 7-Strings Are Used For
Extended low-register riffing. The most common use — palm-muted, heavy riffs on the low B string that sit below what a standard 6-string can reach without detuning the entire instrument.
Maintaining standard tuning for leads and chords. Because the top six strings stay standard, you can play conventional lead lines, chord voicings, and techniques exactly as you would on a 6-string, then drop to the 7th string for low riffing within the same song or even the same phrase.
Extended chord voicings. Some players use the low B string to add bass notes beneath standard chord shapes, creating richer voicings than six strings alone allow.
Progressive and technical metal. Bands like Dream Theater, Animals as Leaders, and Periphery use 7-strings (and sometimes 8-strings) extensively for the combination of extended range and technical, often polyrhythmic playing that defines the genre.
What’s Different About Playing a 7-String
Wider neck. An additional string requires a wider neck to maintain comfortable string spacing. This is the most immediately noticeable difference when picking up a 7-string for the first time — your fretting hand needs to adjust to a slightly broader reach.
Right-hand muting becomes more important. With an additional bass string, unwanted string noise becomes more noticeable, especially under high gain. Palm muting technique and careful right-hand control matter more on a 7-string than a standard 6-string.
Heavier overall string tension setup. Most 7-string guitars use longer scale lengths (often 25.5” to 27”, sometimes with a multi-scale/fanned-fret design) to maintain appropriate tension on the low B string. This is worth understanding before buying — a 7-string isn’t simply a 6-string with an extra string bolted on; the whole instrument is typically engineered around the extended range.

Is a 7-String Right for You?
Yes, if:
- You play progressive, technical, or nu-metal styles that use extended low-range riffing
- You want both standard guitar tuning and lower-register access from one instrument
- You’re comfortable adapting to a slightly wider neck
Consider alternatives if:
- You’re a beginner — develop standard 6-string technique first; the extended range and wider neck add complexity that’s better tackled once fundamentals are solid
- You only need lower pitch occasionally — detuning a standard guitar or using a baritone may suit you better depending on context
- You play styles where extended range isn’t relevant (blues, folk, pop, classic rock)
