That extended low B is the whole reason you bought an eight string, and the wrong strings turn it to mush. A floppy bottom string smears every riff, so the set you choose matters more here than on any six string.
A grab-bag six string pack won’t cut it. You need a purpose-built set that keeps the thick strings tight and the tension even from the high E all the way down.
Tuning drives the gauge you want. Lighter 9-72 and 9-80 sets suit players near standard, while heavier 10-74 and 10-85 sets are made for drop tunings and harder styles.
This guide ranks five sets by how well they hold pitch, how tight the low strings sit, their tone, and how much you get for the money. If you’re upgrading the hardware too, our 8 string pickups guide pairs nicely with fresh strings.

Taming the Low F#
The bottom string tells the story: 85 thousandths on the Stringjoy Heavy Bottom, 80 on the Ernie Ball Skinny Top, 72 on the lighter GHS set. Heavier means tighter chug under drop tunings.
The D’Addario NYXL set wins on engineering, a 40% stronger core wire built for exactly the tension an eight string applies.
1. D’Addario NYXL0980
D'Addario NYXL0980
Premium uncoated 09-80 nickel-plated set with NY Steel core for stronger, more stable strings and enhanced mid-range.
Pros
- Stays in tune 131% better than standard strings
- NY Steel core is up to 40% stronger and resists breakage
- Accentuated 1 to 3.5 kHz range cuts through the mix
- Drawn to spec at the New York production facility
Cons
- Premium price compared to standard sets
- Uncoated, so they need wiping after sweaty sessions
The NYXL0980 is the set we reach for first on any eight string, and the numbers back it up: D’Addario rates it to stay in tune 131% better than standard strings, with a NY Steel core wire that’s up to 40% stronger and far less prone to snapping under bends. The accentuated frequency response in the 1 to 3.5 kHz range gives the low strings real presence and crunch so the riffs cut through a dense mix instead of disappearing.
Bent two whole steps higher, these strings are still at less than 75% of their breaking point, which tells you everything about how much abuse they shrug off. They’re drawn to spec at D’Addario’s New York facility, and the only real trade-off is the premium price and the wiping any uncoated set needs after a sweaty session.
2. Stringjoy HVY108 Heavy Bottom
Stringjoy HVY108 Heavy Bottom
Heavy bottom light gauge 10-85 nickel set mathematically balanced for even tension across the whole fretboard.
Pros
- Heavy 85 low string holds tight in low drop tunings
- Tension mathematically optimized for even feel
- Every set inspected by three people for tuning stability
- Backed by a no ifs, ands, or buts guarantee
Cons
- Heavier bottom gauge is stiffer for fast leads
- Boutique brand carries a higher price
If you tune low and play heavy, the Stringjoy HVY108 is the standout. This heavy bottom light gauge set runs 10-85, and that thick 85 low string holds tension tight in drop tunings where lighter sets go slack.
Stringjoy mathematically optimizes the tension across every gauge, so the feel stays smooth and even from the fretboard’s top to bottom rather than fighting you on the heavy strings.
Quality control is a genuine selling point here, with every set inspected by three different people to make sure the strings resonate, intonate, and stay in tune. The brand also stands behind the product with a no ifs, ands, or buts guarantee.
The heavier bottom is a touch stiffer for fast lead work, and the boutique pricing sits above the mass-market sets.
3. Ernie Ball 8-String Skinny Top Heavy Bottom
Ernie Ball 8-String Skinny Top Heavy Bottom
Nickel wound 9-80 set with skinny top and heavy bottom gauges for bright leads and a tight low end.
Pros
- Skinny top heavy bottom mix balances lead bite and low tension
- Nickel-plated wrap over a hex steel core for a bright tone
- Tin-plated high-carbon plain strings stay well balanced
- Signature Slinky feel familiar to Ernie Ball players
Cons
- Plain strings can fray faster than coated sets
- 80 low B feels loose for very low tunings
The Ernie Ball Skinny Top Heavy Bottom is the dependable middle-ground pick, pairing thinner high strings for easy bends with heavier 9-80 bottom gauges for a tighter low end. The nickel-plated steel wrap sits over a hex-shaped steel core, while the plain strings use tempered tin-plated high-carbon steel, and together they deliver the bright, well-balanced tone Ernie Ball is known for.
You also get that signature Slinky feel that makes these so familiar under the fingers, manufactured in California to consistent specs. They’re a reliable everyday choice, though the plain strings can fray a little faster than coated sets, and the 80 low B can feel slightly loose if you drop into the lowest tunings.
4. GHS GBXL-8 Boomers
GHS GBXL-8 Boomers
Extra light 9-72 nickel-plated Boomers set designed with extended range guitarists for lower tunings.
Pros
- Extra light 9-72 gauge is easy on the fingers
- Designed with input from extended range guitarists
- Classic bright Boomers attack many players know
- Affordable everyday set for regular restrings
Cons
- 72 low string is light for heavy drop tuning
- Brighter tone fades faster than premium sets
The GHS GBXL-8 is the value champion of the group. This extra light 9-72 set was designed with the help of extended range guitarists, bringing the bright, punchy Boomers attack that GHS built its name on into lower territory.
The lighter gauges make it easy on the fingers and forgiving for players who are newer to the wider neck of an eight string.
For anyone staying close to standard tuning who restrings often, the affordable price makes the GBXL-8 an easy set to keep stocked. The trade-offs are predictable for a lighter set: the 72 low string lacks the tension you want for heavy drop tunings, and the bright tone mellows out a bit faster than the premium options.
5. Ernie Ball 2625 Slinky (3-Pack)
Ernie Ball 2625 Slinky (3-Pack)
Three-pack of nickel-wound Slinky sets with a hex steel core and heavier 10-74 gauge for thicker tone.
Pros
- Three sets per pack lowers the cost per restring
- Heavier 10-74 gauge adds tension and sustain
- Nickel-plated wrap over a hex steel core
- Signature Slinky feel from a trusted brand
Cons
- Heavier gauge is stiffer for standard tuning
- Fewer published specs than the premium sets
The Ernie Ball 2625 lands here mostly on value, arriving as a three-pack that drops your cost per restring considerably. The heavier 10-74 gauge brings extra tension and sustain, built on the same nickel-plated wrap over a hex steel core that gives these sets their familiar bright Slinky character.
If you blow through strings and want a trusted brand on hand in bulk, this pack makes sense. The heavier gauge is noticeably stiffer in standard tuning, and there are fewer published specs to go on than the premium sets up the list, which is why it rounds out the roundup rather than climbing higher.
Final Thoughts
The D’Addario NYXL0980 is our top pick for an eight string, and it isn’t especially close. The 131% better tuning stability and 40% stronger core mean the bottom strings hold pitch through hard bends and aggressive riffing, and the boosted mid-range keeps those low notes defined instead of muddy.
For most players it’s the set that simply works and keeps working.
If your eight string lives in drop tunings, the Stringjoy HVY108 is the smarter buy. Its 10-85 heavy bottom keeps the lowest string tight where lighter sets turn to spaghetti, and the obsessive triple-inspection quality control means you can trust it to stay in tune set after set.
On a budget, the GHS GBXL-8 Boomers deliver a bright, playable 9-72 set for a fraction of the cost.
Whichever set you choose, match the low string gauge to how low you tune and you’ll get clear, punchy riffs instead of a flabby bottom end. Once the strings are sorted, take a look at our guide to tuning an 8 string guitar to dial in the rest.
