D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings Review: The Ultimate Voice for Your Acoustic Low B
If you have ever owned a 5-string acoustic bass, you know the specific brand of frustration that comes with finding the right set of strings. I remember the first time I brought home a beautiful jumbo-bodied 5-string acoustic. Unplugged, the G, D, A, and E strings sang with a woody, percussive chime. But the moment I struck that low B, the heart of the instrument seemed to skip a beat. It was floppy, muddy, and lacked the “thump” required to keep up with the other four strings. This is a common struggle for bassists: most acoustic bass strings are designed for 4-string models, and the 5-string sets often feel like an afterthought. Solving this tonal imbalance is crucial because a 5-string bass is only as good as its lowest note. Without a string that can move enough air and maintain tension, your expensive instrument becomes a glorified 4-string. This led me on a quest to find a set that could actually handle the physics of a low B on an acoustic chamber, which eventually brought me to the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings.
D'Addario's EPBB170-5 provides a rich, deep and projecting tone for all 5-String acoustic basses.
Phosphor Bronze was introduced to string making by D'Addario in 1974 and has become...

What to Consider Before Buying Bass Guitar Strings
A Bass Guitar Strings is more than just an item; it’s a key solution for defining your instrument’s fundamental character, playability, and longevity. When you change your strings, you aren’t just performing maintenance; you are performing a tonal upgrade. The right set of strings can breathe life into a dull-sounding bass, while the wrong set can make a premium instrument feel cheap and unresponsive. For acoustic bass players, the stakes are even higher because you don’t have an amplifier to “fix” your tone in the room; the string must do all the heavy lifting of vibrating the soundboard.
The ideal customer for this type of product is someone facing the “muddy B” syndrome or someone who performs in unplugged settings where projection is paramount. It is for the player who values a balanced, “woody” tone that complements the natural resonance of a hollow body. While it might not be suitable for those who prefer the slippery feel of flatwounds or players who primarily play high-gain electric bass and want a “clanky” metallic sound, it is the gold standard for pure acoustic performance. Before investing, consider these crucial points in detail:
Before investing, consider these crucial points in detail:
- Gauge and Tension: The gauge, specifically the .130 low B in this set, determines how much tension is placed on the neck and how much “floppiness” you’ll experience. A thicker gauge generally provides a more stable low B but requires more finger strength to fret.
- Material Composition: Phosphor Bronze (92% copper, 8% tin, and a trace of phosphorus) is the industry standard for a reason. It offers a warmer, more complex harmonic profile than 80/20 bronze, which can sometimes sound overly brittle or “zinc-heavy” on an acoustic bass.
- Scale Length Compatibility: You must ensure the strings match your bass’s scale length. The D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings are “Long Scale,” meaning they fit instruments with a string scale length of up to 36 1/4 inches. Using the wrong scale length can lead to strings snapping or not reaching the tuning pegs properly.
- Corrosion Resistance: Since acoustic strings are often uncoated, they are susceptible to oils from your skin and humidity. Look for brands that use high-quality alloys and protective packaging to ensure the strings are fresh the moment you open them.
Choosing the right strings involves balancing these technical needs with your personal playing style. While the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings is an excellent choice, it’s always wise to see how it stacks up against the competition.

First Impressions and Key Features of the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings
When I first unboxed the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings, the first thing I noticed was the packaging. D’Addario uses a VCI (Vapor Corrosion Inhibitor) plastic bag that is heat-sealed. This might seem like a small detail, but in the world of phosphor bronze—which can tarnish if exposed to air—it ensures that the strings arrive as bright and “new” as the day they were wound in New York. You can see its full feature set and user reviews to understand why this level of precision matters to professional players.
The strings themselves have a distinct, rich copper-orange hue characteristic of high-quality phosphor bronze. Taking them out of the bag, the winding felt consistent and tight. D’Addario pioneered the use of phosphor bronze in string making back in 1974, and that heritage shows. The hex-core construction is visible at the ends, providing a clear indication of the structural integrity. Compared to budget “store brand” strings I’ve used in the past, these felt significantly more substantial. I was eager to see if the .130 gauge low B would provide the tension I was missing. Before we dive into the sound, it’s worth checking the latest price and availability for these sets, as they are often the only reliable 5-string acoustic sets found online.
Key Benefits
- Exceptional Low B tension that eliminates “floppiness” on acoustic bridges.
- Rich, complex harmonic overtones thanks to the 1974-original Phosphor Bronze formula.
- Corrosion-resistant eco-friendly packaging keeps strings fresh indefinitely.
- Made in the USA with high-carbon steel hex cores for superior intonation.
Drawbacks

- The roundwound texture can be slightly “rough” on the fingers for beginners.
A Deep Dive into the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings’ Performance
The “Low B” Solution: Tension and Clarity
The most critical aspect of any 5-string set is the fifth string. On an acoustic bass, the body isn’t always large enough to naturally amplify a low B (approx. 31 Hz) with authority. I found that the .130 gauge string in the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings set is expertly engineered to combat this. During my testing, I noticed that the string maintained a stiff, reliable tension that didn’t rattle against the frets even when played with a heavy thumb-plucking technique. This is a feature that really sets it apart from lighter sets that often feel like rubber bands.
In a live, unplugged environment, the low B actually projected. Instead of a dull “thud,” there was a discernible pitch and a “growl” that allowed me to hold down the low end of an acoustic ensemble without disappearing into the mix. This is supported by user feedback from bassists who have struggled with other brands where the B-string felt dead out of the box. With D’Addario, the consistency of the winding onto the high-carbon steel hex core ensures that the string vibrates uniformly, which is the secret to its clarity. We found that even when dropped-tuned slightly, the string held its intonation across the entire fretboard, a feat many acoustic 5-string sets fail to achieve.
Tonal Profile: Warmth Meets High-End Definition
The D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings are designed to provide a “balanced” tone, but what does that actually mean in practice? When I first strung up my bass, the “new string zip” was certainly present, but it wasn’t the piercing, metallic clank you get from stainless steel electric strings. Instead, it was a shimmering high-end that complemented the woody “thump” of the acoustic body. As the strings broke in over the first 48 hours, they settled into a sweet spot of warm mids and punchy lows. This is the sonic quality that many users rave about, noting that even as the strings “age,” they maintain a usable resonance.
I specifically tested these strings on a semi-hollow fretless 5-string to see how they handled “mwah” and sustain. The results were impressive. Unlike black nylon tapewounds, which can sometimes sound too dark and muted, these phosphor bronze strings provided the necessary “bite” to let the fretless character shine through. The sustain was significantly longer than cheaper alternatives, allowing for those long, singing low notes that are essential for jazz or folk accompaniment. The precision winding ensures that there are no “dead spots” on the string, which is crucial for maintaining a consistent volume across all five strings.
Durability and the Phosphor Bronze Advantage
One of the biggest complaints about acoustic strings is how quickly they “die” due to oxidation. Because the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings are uncoated, they rely on the quality of the alloy itself to resist the elements. In our evaluation, we found that the inclusion of phosphorus in the bronze alloy really does act as a buffer against corrosion. While I always recommend wiping your strings down after a session, these strings held their “brightness” for several weeks of heavy play. I was particularly impressed by how they handled humidity changes in my studio.
A user mentioned that they keep their bass in a closet for long periods and noticed some tarnishing, which is to be expected with any non-coated string. However, even when they visually “darkened,” the fundamental tone remained intact. This “residual mid-high resonance,” as one user described it, is what makes D’Addario a “go-to” brand for professionals. You aren’t just paying for the first ten hours of play; you are paying for strings that will still sound musical three months down the line. For those who want the best value for their money, you can check the current deals on these strings to see how they fit into your maintenance budget.
Playability and Physical Feel
We need to talk about the “feel” of these strings. Being roundwound and phosphor bronze, they have a tactile, slightly “grippy” texture. For players transitioning from smooth flatwounds or coated electric strings, there might be a brief adjustment period. I found that this texture actually helped with my control, especially during fast, rhythmic “percussive” acoustic playing where I use the strings to create a drum-like effect on the body of the bass. The strings didn’t feel overly stiff to the fingers, despite the high tension of the .130 low B.
The “Long Scale” length (34-inch standard) means the taper starts at the right place for most 5-string acoustic basses. I’ve had issues with other brands where the thick part of the string wraps around the tuning peg, leading to breakage. D’Addario’s specifications are spot-on, ensuring the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings performs under pressure. Whether you are performing a delicate fingerstyle piece or digging in with a heavy pick, the strings respond dynamically to your touch. This tactile feedback is essential for an acoustic instrument, where the connection between the player’s fingers and the vibrating wood is so direct.
What Other Users Are Saying
The consensus among the global bass community is overwhelmingly positive, with several users highlighting that these are essentially the “only” viable option for 5-string acoustic players. One dedicated user noted that these are their “go-to” strings because the bronze carries a depth that cheaper shelf brands lack, even after the strings have “gone dark.” This sentiment is echoed by international players; a Japanese bassist mentioned that switching to these from black nylon strings dramatically improved their “body resonance” and solved their sustain issues. It is clear that the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings are respected for their ability to turn a quiet acoustic bass into a projecting powerhouse.
However, the feedback isn’t without its caveats. Some users have pointed out that because these strings are phosphor bronze and uncoated, they can be “a little rough” on the fingertips and are prone to tarnishing if not properly maintained. One user reported receiving a defective B-string, but they were quick to praise D’Addario’s customer service, which replaced the string in just three days. This highlights a crucial point: while no manufacturing process is perfect, D’Addario stands behind their “replaced if defective” warranty, which builds immense trust with the consumer. Overall, the community views these as a premium, reliable choice that justifies its slightly higher price point through superior harmonics and longevity.
Comparing the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings to Top Alternatives
1. Elixir NANOWEB 5-String Bass Strings Light 45-130
- LONGEST-LASTING TONE: Made with stainless steel wrap wire and our proprietary NANOWEB Technology, these strings deliver a bright tone, with a comfortable and smooth feel
- BRILLIANT TONE: Often top-rated, you can trust Elixir Strings for their consistently reliable performance. From our light bass strings to our heavier gauges
If your primary concern is how long a string stays “bright,” the Elixir NANOWEB is the main competitor. Unlike the uncoated D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings, these feature a ultra-thin polymer coating that protects the string from skin oils and gunk. Tonally, they are made of stainless steel, which provides a much more “electric,” metallic “clank” compared to the warm, woody tone of the D’Addario bronze. A player might prefer these if they have very acidic sweat that kills strings in a week, or if they are playing an acoustic-electric bass through a high-fidelity preamp and want that modern, “zingy” sound. However, for a pure acoustic unplugged session, they lack the organic warmth of phosphor bronze.
2. Elixir Electric Bass Guitar Strings, 5-String Long Scale Set
- LONGEST-LASTING TONE: Made with nickel plated steel wrap wire and our proprietary NANOWEB Technology, these strings deliver a warm and rounded tone, with a comfortable and natural feel
- BRILLIANT TONE: Often top-rated, you can trust Elixir Strings for their consistently reliable performance. From our light bass strings to our heavier gauges
These nickel-plated steel strings are another coated option from Elixir, offering a “warmer” tone than their stainless steel counterparts but still leaning heavily into the electric bass world. While they are a “Long Scale” set with a similar .130 B-string, they are fundamentally designed for electric basses. When put on an acoustic instrument, they can feel a bit “sterile.” I would recommend these for the gigging musician who uses their acoustic bass in a loud band setting with a pickup and wants the comfort of a coated string. But if you are looking for the “bronze shimmer” that defines an acoustic guitar or bass, the D’Addario EPBB170-5 remains the superior choice for tonal authenticity.
3. Ernie Ball 5-String Flatwound Bass Strings 45-130
- Ernie Ball Custom Gauge Flatwounds deliver solid low-end with reduced finger noise
- Flattened stainless steel wrap wire on a hex-shaped tin-plated steel core
Ernie Ball’s flatwounds are the polar opposite of the D’Addario roundwounds. They are smooth to the touch and produce a deep, “thumpy,” and vintage tone with almost zero finger noise. Someone would choose these if they want their acoustic bass to sound more like an upright double bass and less like an acoustic guitar. They are excellent for jazz and soul. However, they lack the projection and high-end clarity of the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings. If you find roundwounds too “rough” or “bright,” these are your best bet, but be prepared to lose the shimmering harmonics that make an acoustic instrument “cut through” a room.
Final Verdict: Are These the Best 5-String Acoustic Strings?
After weeks of testing and comparing, it is clear that the D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings occupy a unique and necessary space in the market. They solve the two biggest problems facing 5-string acoustic bassists: a floppy low B and a lack of unplugged projection. The .130 gauge B-string is the star of the show, providing the physical tension required to drive an acoustic soundboard effectively. While the uncoated nature of the strings means you have to be diligent about cleaning them, the reward is a harmonically rich, woody tone that coated or nickel strings simply cannot replicate. I would recommend these to any 5-string player who wants their instrument to sound like a true acoustic bass rather than a quiet electric one.
If you are tired of your 5th string sounding like a muddy mess and want a set of strings that are built with the precision and heritage of the original phosphor bronze pioneers, this is the set for you. They are durable, tonally superior to budget brands, and backed by excellent customer support. Don’t let your 5-string bass stay in the closet because it doesn’t sound right; grab a set of D’Addario EPBB170-5 Phosphor Bronze 5-String Bass Strings today and finally hear what your instrument is capable of.
