The rise of seven strings

You’re hearing it everywhere now—that low rumble and the weight of an extra string. It isn't just for extreme metal anymore. I see 7-strings showing up in mainstream rock and pop sessions more than ever. 2026 feels like the year it finally stops being a 'specialty' instrument and just becomes another tool in the rack.

The story doesn't begin today, though. Back in the 90s, guitarists like Steve Vai and Allan Holdsworth were among the first to explore extended-range instruments, pushing the boundaries of what was possible on the fretboard. Holdsworth, in particular, was a pioneer, using a custom-built 7-string to achieve his signature fluid legato style. These were early experiments, largely unknown to the average guitarist.

For years, the 7-string remained a tool for a select few. But the emergence of bands like Meshuggah in the late 90s and early 2000s changed everything. Their innovative use of polyrhythms and heavily downtuned 7-string guitars laid the foundation for the 'djent' movement, and with it, a massive surge in interest in extended-range instruments. The appeal is simple: more range means more notes, more possibilities, and a fuller, more powerful sound. It allows for complex chord voicings and riffs that are simply impossible on a standard 6-string.

Now, we’re seeing the influence of that early innovation spread. More and more guitar manufacturers are offering 7-string models, and a new generation of players are embracing the instrument. It’s not just about extreme metal anymore; the 7-string is finding its way into progressive rock, jazz fusion, and even pop music. The demand is there, and the industry is responding.

Tuning and string gauges

Okay, you’re intrigued by the 7-string. The first thing you need to figure out is how to tune it. Standard tuning (B E A D G B e) is a good starting point, offering a natural extension of the low E string. However, many players opt for lower tunings, like drop A (A E A D G B e), which is popular in djent and metalcore. Other common tunings include drop G# and even lower, depending on the desired sound.

Tuning significantly impacts string gauge. Going lower requires heavier strings to maintain tension and prevent floppiness. I’ve spent countless hours experimenting with different gauges, and I’ve found that a set of strings ranging from .009 to .064 is a good all-around choice for standard tuning. For drop A, I usually go with .010 to .070. But this is just a starting point. String gauge is a very personal preference, and it depends on your playing style and the scale length of your guitar.

Finding the right setup often involves trial and error. You might need to adjust your truss rod, intonation, and even your nut slots to accommodate the heavier strings. Don't be afraid to experiment and consult with a qualified guitar technician if you’re unsure. A properly set up 7-string will play much better and sound much more in tune.

Beyond djent

It's impossible to talk about the 7-string’s rise without acknowledging the influence of djent. Bands like Meshuggah, Periphery, and Animals as Leaders were instrumental in popularizing the instrument and defining its sonic aesthetic. Their innovative use of polyrhythms, syncopation, and heavily distorted tones created a unique and instantly recognizable sound that captivated a generation of guitarists.

But the 7-string's influence extends far beyond djent. Progressive metal bands like Dream Theater and Opeth have incorporated the instrument into their complex and dynamic compositions. Deathcore bands like Whitechapel and Suicide Silence utilize the 7-string for its crushing low-end and aggressive tone. Even jazz fusion artists like Tosin Abasi (Animals as Leaders) have embraced the instrument’s versatility.

What’s fascinating is how the 7-string allows musicians to explore new harmonic and melodic territory. The extended range opens up possibilities for wider interval voicings, more complex chord progressions, and more expressive soloing. It’s not just about playing lower; it’s about creating a richer, more nuanced sound. Take Plini, for example. His incredibly melodic and atmospheric playing showcases the 7-string’s potential beyond aggressive riffing.

The instrument is becoming increasingly accepted across genres. The 7-string is no longer a novelty; it’s a legitimate musical tool that’s being used by a diverse range of artists to push the boundaries of their respective genres.

New techniques

The 7th string isn't just about adding a low B; it unlocks a whole new world of playing techniques. Extended-range chords become readily accessible, allowing you to create fuller, more complex harmonic textures. Instead of struggling to barre awkward chord shapes on a 6-string, you can often find a more comfortable and efficient voicing on a 7-string.

Wider interval voicings are another key benefit. The extra string allows you to stretch your chords and create more spacious, atmospheric sounds. This is particularly useful for creating ambient textures or adding a sense of grandeur to your compositions. Think about the possibilities for creating unique chord inversions and voicings that simply aren’t possible on a standard guitar.

The expanded melodic possibilities are also significant. You can now play melodies and runs that extend beyond the range of a 6-string, allowing for more expressive and dynamic solos. The extra string also provides more options for tapping and legato techniques. It encourages a different approach to the fretboard.

These techniques aren’t just for shredders. They can be applied to a wide range of playing styles, from fingerstyle acoustic to heavy metal riffing. The key is to experiment and find ways to incorporate the 7th string into your existing playing vocabulary.

7-String Sweep Picking Arpeggio in B Minor: A Beginner's Guide

1
Understanding the Low B String

The addition of a low B string on a 7-string guitar expands the tonal range and opens up new possibilities for chord voicings and arpeggios. This B string is typically tuned one octave below the high E string. Familiarize yourself with its feel and how it interacts with the other strings. Initial practice should focus on clean picking of individual notes on the B string before attempting arpeggios.

2
The B Minor Arpeggio Shape

We'll be learning a common B minor arpeggio shape. This shape utilizes the root (B), minor third (D), fifth (F#), and octave (B) of the B minor chord. The fingering we'll use is: Index finger on the 7th fret of the B string, middle finger on the 9th fret of the B string, ring finger on the 7th fret of the E string, and pinky finger on the 9th fret of the E string. This provides a comfortable and efficient position for sweeping.

3
The Sweep Picking Motion

Sweep picking involves moving the pick smoothly across multiple strings in a single direction – either downsweep or upsweep. For this arpeggio, we'll start with a downsweep. The key is to synchronize the pick movement with your fretting hand, ensuring each note rings out clearly. Avoid digging in with the pick; aim for a light, fluid motion. Practice slowly at first, focusing on accuracy and evenness.

4
Executing the Downsweep

Begin by positioning your pick over the B string at the 7th fret. Initiate a downsweep, hitting the B string, then the E string at the 7th fret, and finally the E string at the 9th fret. Maintain consistent pressure and speed throughout the sweep. Immediately after the sweep, lift the pick slightly to avoid unwanted noise. Repeat this motion several times, focusing on clean articulation of each note.

5
Adding the Octave and Returning

Now, incorporate the octave note on the B string (9th fret). The complete arpeggio sequence is: B string 7th fret, B string 9th fret, E string 7th fret, E string 9th fret. After sweeping down, you will need to reverse the motion to return to the starting position. This requires a smooth upsweep, hitting the notes in reverse order.

6
Synchronization and Rhythm

The most challenging aspect of sweep picking is synchronizing the picking and fretting hands. Use a metronome to practice at a slow tempo, gradually increasing the speed as your accuracy improves. Focus on maintaining a consistent rhythm and ensuring each note is clearly defined. Record yourself playing and listen back critically to identify areas for improvement.

7
Expanding the Arpeggio

Once you're comfortable with this basic shape, experiment with moving it up and down the neck. This will allow you to play the B minor arpeggio in different positions, creating a wider range of musical possibilities. Also, try incorporating other notes from the B minor scale to create more complex arpeggio patterns.

Guitars and pickups

The 7-string market is growing, and there's a wider range of guitars available than ever before. Ibanez is a long-standing player in this space, with models like the RG7 and Universe series being popular choices. Schecter also offers a variety of 7-string guitars, catering to different styles and budgets. More recently, companies like Strandberg have gained recognition for their innovative headless designs.

Republic Guitars offers a range of instruments, including those with a focus on quality construction and sound (as seen on their website). While not exclusively 7-string focused, their commitment to craftsmanship suggests they could be a viable option for players seeking a unique instrument. Body wood, neck profile, and hardware all play a role in the overall feel and sound of the guitar. Mahogany typically provides a warm, resonant tone, while maple offers a brighter, more articulate sound.

Pickups are crucial. The low B string requires a pickup that can deliver a clear, powerful signal without getting muddy. High-output humbuckers are a popular choice, but active pickups can also provide excellent clarity and definition. Fishman Fluence, Bare Knuckle Pickups, and Lundgren are all well-respected brands that offer high-quality 7-string pickups.

Don’t get caught up in brand wars. Focus on finding a pickup that complements your playing style and the type of music you play. Consider the magnetic pull of the pickup and how it affects the sustain and intonation of the low B string. A well-chosen pickup can make a huge difference in the overall sound of your 7-string.

Amps and signal chains

Standard guitar amps often choke on a low B. They aren't designed to push those frequencies, so you end up with a flubby mess. I usually suggest using a high-headroom tube head or moving toward full-range cabinets that can handle the extra excursion without farting out.

Impulse responses (IRs) and digital modeling have become increasingly popular for achieving a tight and defined 7-string tone. IRs capture the sonic characteristics of a specific speaker cabinet and allow you to recreate that sound digitally. Digital modeling amps, like those from Kemper and Fractal Audio, offer a wide range of amp models and cabinet simulations.

My personal preference is to use a combination of a tube amplifier and an IR loader. I find that the tube amp provides warmth and dynamics, while the IR loader allows me to fine-tune the cabinet response. I typically use a scooped mid-range EQ setting to emphasize the low end and a touch of compression to tighten up the sound. A noise gate is also essential for eliminating unwanted hum and noise.

Experiment with different effects pedals to create your own signature tone. Octave pedals can add depth and texture, while delay and reverb can create atmospheric soundscapes. Don't be afraid to push the boundaries and explore unconventional effects combinations.
