Finding the right 8 string classical guitar strings can feel like a bit of a scavenger hunt compared to picking up a standard six-string pack at your local music shop. If you've made the jump to an extended-range instrument, you already know that those two extra bass strings change everything about how the instrument breathes and vibrates. It's not just about adding more notes to your range; it's about finding a set that doesn't sound like a muddy mess or feel like bridge cables under your thumb.
Most players who pick up an 8-string are looking for that piano-like depth, especially if they're playing transcriptions of Bach or more modern, experimental pieces. But the physics of those low strings can be a real headache. You're dealing with more tension on the bridge, a wider neck, and the constant struggle of finding a low B or low G that actually has some "snap" to it.
Why the Extra Strings Change the Game
When you add a 7th and 8th string, you aren't just widening the fretboard; you're fundamentally changing the resonance of the guitar's top. Standard 8 string classical guitar strings need to account for this. Most 8-string guitars are tuned with an extra low B and low A, or sometimes a low D and low C depending on the repertoire.
The biggest issue I've run into—and I'm sure many of you have too—is the "floppy string" syndrome. If the gauge of those low strings isn't just right, they end up sounding dull and thumpy rather than clear and resonant. You want a bass note that rings out with some authority, not something that sounds like you're plucking a rubber band. This is why tension is the first thing you need to look at.
Understanding Tension and Gauge
In the world of classical guitar, we don't usually talk about "light" or "heavy" gauges like electric players do. Instead, we talk about tension: normal, high, or extra-high. When you're hunting for 8 string classical guitar strings, tension becomes your best friend and your worst enemy.
High Tension for the Low End
I usually recommend leaning toward high tension for the 7th and 8th strings. Because these strings are so thick and tuned so low, they need that extra internal tension to keep from vibrating too wide and hitting the frets. There's nothing more annoying than a beautiful low-bass passage being ruined by a constant clack-clack against the fingerboard.
Balancing the Trebles
However, you don't always want high tension across the whole set. Some players find that high-tension trebles (the E, B, and G) can feel a bit stiff or "choked." A popular trick is to mix and match. You might use a standard high-quality set for the top six and then source specific individual strings for the 7th and 8th. But luckily, a few brands have started doing the legwork for us by creating dedicated 8-string sets that are already balanced.
The Big Names in the 8-String World
You won't find a dozen different brands for these instruments on every shelf, but the ones that do make them are usually top-tier.
Hannabach is probably the most famous name here. They've been making specialized sets for decades. Their 8-string sets are known for being incredibly consistent, though they can be a bit pricier. If you want that traditional, "German-engineered" precision, they're hard to beat. Their basses have a certain "growl" that really brings out the character of an extended-range guitar.
Savarez is another heavy hitter. They often use their Alliance carbon trebles in their extended sets. If you find your 8-string sounds a bit dark or "woody," carbon trebles can add some much-needed brightness and projection. Their basses are typically very flexible and easy to play, which is a blessing when you're trying to stretch your hand across a massive 8-string neck.
D'Addario also offers options, though they are sometimes more common as "custom" or "add-on" singles. They're a great "everyday" string—reliable, affordable, and they break in relatively quickly.
Custom Sets vs. Pre-Packaged Sets
Let's be honest: sometimes the pre-packaged 8 string classical guitar strings don't quite hit the mark for your specific guitar. Every luthier-built 8-string has its own personality. Some have a 650mm scale length, while others are multi-scale (fanned frets).
If you find that the 8th string in a standard set feels too loose, don't be afraid to buy individual strings. Many players buy a standard 6-string set of their favorite brand—say, Augustine or Labella—and then buy two single bass strings from Hannabach or Savarez to complete the range. It takes a bit more effort to track them down, but your ears will thank you.
Carbon vs. Nylon Trebles
Since we're talking about 8 string classical guitar strings, we can't ignore the treble material. With all that extra bass energy vibrating the guitar's body, your trebles can sometimes get "lost" in the mix.
- Nylon trebles offer that warm, sweet, romantic sound. If you're playing a lot of melodic, lyrical music, you'll probably prefer these.
- Carbon trebles are thinner and denser. They have a faster attack and a brighter tone. For an 8-string, carbon is often a life-saver because it helps the higher melodies cut through the massive wall of sound created by the extra bass strings.
Tuning Stability and Break-in Time
We've all been there—you put on a fresh set of strings and they won't stay in tune for more than five minutes. With an 8-string, this problem is amplified. You've got two more "stretchy" nylon cores to deal with.
I've found that the 7th and 8th strings actually take a bit longer to settle than the standard basses. Because they are thicker, they have more "memory" and take more time to stretch out fully. A little tip: when you're winding those heavy basses onto the tuning pegs, make sure you don't have too many overlaps. It can lead to "slippage," which makes you think the string is stretching when it's actually just sliding around the post.
Maintenance and Longevity
The 7th and 8th strings don't usually get played as often as the 1st or 4th, but they still age. Sweat and oils from your hands will eventually deaden the wrap wire. Since 8 string classical guitar strings are more expensive and harder to find, you'll want to make them last.
Give them a quick wipe down after every session. It sounds like a chore, but it really does keep that "zing" in the bass strings for an extra week or two. Once those low notes go dead, the whole instrument starts to sound unbalanced. You'll have these bright, singing trebles and then a low C that sounds like a wet cardboard box. Not exactly the "concert hall" vibe you're going for.
Wrapping it All Up
Choosing 8 string classical guitar strings is a deeply personal journey. There's no "one size fits all" because so much depends on your guitar's scale length and your own playing style. Whether you go with a pre-packaged set from Hannabach or a Frankenstein-style custom set of your own design, the goal is always the same: clarity, balance, and a bass response that makes the floor vibrate.
Don't be afraid to experiment. Try a high-tension set once, then try a mixed-tension set the next time. Eventually, you'll find that perfect combination that makes your 8-string feel less like a challenge and more like a natural extension of your musical voice. It might take a few tries to get it right, but when you hit that first low A and it rings out clear as a bell, all the searching will be worth it.
