Ernie Ball Slinky Short Scale Bass Strings 20w-90 Review: The Ultimate High-Tension Solution for Hybrid Players
If you have ever picked up a 30-inch scale 6-string bass, like a Danelectro, a Schecter Hellcat, or the legendary Bass VI, you know the immediate struggle. These instruments sit in a strange, wonderful purgatory between a guitar and a traditional long-scale bass. The problem? Finding strings that actually fit. Most standard bass strings have ball ends too large for the bridges, and most guitar strings are far too short and thin to provide that foundational low-end thump. We have spent countless hours in the studio trying to bridge this gap, often settling for expensive custom sets or “franken-stringing” various gauges together just to get through a session.
When the tension is off, the instrument becomes unplayable. A low E string that is too floppy ruins your intonation, while a high E that is too brittle snaps under the pressure of hybrid picking. This is where the Ernie Ball Slinky Short Scale Bass Strings 20w-90 enter the fray. They promise a specialized solution for a very specific problem: providing the “Slinky” feel and iconic nickel-wound tone to the 6-string short-scale world. Solving this tension puzzle is crucial for any player who wants their Bass VI-style instrument to actually sound like a bass rather than just a muddy guitar. Without the right gauges, you are fighting your instrument rather than playing it, leading to tuning instability and a lack of that “tic-tac” clarity that defines this genre of music.
- Made from nickel plated steel wire wrapped around tin plated hex shaped steel core wire
- Manufactured with small ball ends like guitar strings, not large ball ends used on traditional electric bass stings
What to Consider Before Buying Bass Guitar Strings
A set of Bass Guitar Strings is more than just an item; it’s a key solution for defining the harmonic personality and physical playability of your instrument. Whether you are aiming for a vintage Motown thump or a modern, high-definition punch, your choice of string material and gauge will dictate 90% of your raw tone before it even hits your amplifier. For short-scale players, this choice is even more critical because the shorter neck naturally has less tension, making the physical properties of the string the deciding factor in whether your low notes remain articulate or turn into a flubby mess.
The ideal customer for this type of product is someone facing the unique challenges of a 30-inch scale 6-string bass, specifically those who play instruments that use guitar-style bridges and tuners. These are perfect for studio musicians who need “tic-tac” bass sounds or guitarists transitioning to bass who prefer a familiar, tighter feel. However, it might not be suitable for those who own a traditional 34-inch long-scale 4-string bass, as these strings are significantly shorter and thinner than a standard set. If you are looking for traditional heavy-gauge bass strings for a Precision or Jazz bass, you should look toward long-scale specific sets instead.
Before investing, consider these crucial points in detail:
- Dimensions & Scale Length: You must match the string length to your instrument’s scale (distance from nut to bridge). For the Ernie Ball Slinky Short Scale Bass Strings 20w-90, this is designed for 30-inch scales. If your instrument has a “string-through-body” design, you need to ensure the winding length reaches the nut before the taper starts, otherwise, you’ll face breakage or intonation buzz.
- Ball End Size: This is a massive “gotcha” for hybrid players. Traditional bass strings have large ball ends. Many short-scale 6-string basses (like the Bass VI) use guitar-style bridges that require small ball ends. We found that these Ernie Ball strings use the smaller guitar-style ends, which is a lifesaver for compatibility.
- Materials & Durability: Nickel-plated steel is the industry standard for a reason. It offers a balanced magnetic response and a smooth feel under the fingers. While stainless steel is brighter, nickel-plated strings like these tend to be easier on your frets over the long term and provide a warmer mid-range.
- String Gauge & Tension: The 20w-90 range is a “light” set in the bass world but “heavy” in the guitar world. This gauge is designed to provide enough tension to keep the low E (.090) from rattling while keeping the high E (.020) flexible enough for chords and lead lines.
Choosing the right set requires a deep understanding of your specific instrument’s hardware and your personal playing style. Before you make a final decision, it’s worth checking out how these specialized sets compare to more traditional configurations to see which philosophy fits your rig best.
While the Ernie Ball Slinky Short Scale Bass Strings 20w-90 is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Unboxing the Ernie Ball Slinky Short Scale Bass Strings 20w-90
Upon receiving the Ernie Ball Slinky Short Scale Bass Strings 20w-90, the first thing we noticed was the classic Ernie Ball “Element Shield” packaging. This hermetic seal is more than just marketing; it genuinely keeps the strings as fresh as the day they were wound in the California factory. For a product that is often stocked in lower volumes due to its niche nature, knowing that they haven’t been oxidizing on a shelf for a year is a huge plus. You can see its full feature set and user reviews to understand why this packaging matters for longevity.
Pulling them out, the feel is immediately “Slinky.” The nickel plating is smooth, and the hex core construction gives them a certain stiffness that suggests high quality without being rigid. We compared these initially to a set of standard guitar strings and a set of traditional short-scale bass strings. These are noticeably different. The small ball ends are the standout feature here—they look exactly like guitar string ends, which is the “secret sauce” for fitting them into Bass VI or Danelectro bridges without having to drill out the holes. The 20w-90 gauge spread feels intentional, designed to provide a consistent tension curve across all six strings, which is often the biggest flaw in cheaper “generic” sets. Before you even wind them on, you can tell these were engineered for a specific musical purpose.
Key Benefits
- Perfect Bridge Compatibility: The small ball ends fit guitar-style bridges common on 6-string short-scale basses perfectly.
- Bright, Balanced Tone: The nickel-plated steel offers that classic “Slinky” punch that cuts through a mix without being harsh.
- Exceptional Playability: Light enough for chord work and “tic-tac” styles while maintaining enough tension for bass lines.
- American-Made Quality: Freshly sealed packaging ensures no corrosion or “dead” strings out of the box.
Drawbacks & Limitations
- Low E Taper Issues: On some Fender/Squier Bass VI models, the .090 string taper might end before the nut or be tight in the tuning peg.
- Not for Heavy Metal: Players looking for a massive, modern low-end “thump” might find the .090 gauge too light for drop tunings.
A Deep Dive into Performance: Putting the Ernie Ball Slinky Short Scale Bass Strings 20w-90 to the Test
Installation and Hardware Compatibility: The “Small Ball” Revolution
We began our testing by installing the Ernie Ball Slinky Short Scale Bass Strings 20w-90 on a variety of instruments, including a Danelectro and a custom short-scale build. The most immediate win is the ball end size. Most bassists who have tried to put “regular” bass strings on a hybrid instrument have faced the frustration of the ball end simply not fitting into the bridge tailpiece. These strings solve that immediately. We found that the transition from the thick winding to the small ball end is robust; there was no fear of the string snapping at the anchor point, which can be a common issue with lighter hybrid sets.
One thing we must note for our readers: if you are using a Squier or Fender Bass VI, pay close attention to the length. We found that while these are “short scale,” the headstock geometry of certain Fender-style offsets can be demanding. On our test units, the .090 low E fit, but it was a tight squeeze through some standard tuning pegs. However, the benefit of this gauge is that you don’t have to modify your nut slots as aggressively as you would with a .100 or .105 set. You should check the latest price and availability for these strings if you are looking for a “no-drill” solution for your vintage-spec bridge.
Tone Profile: The Iconic Nickel-Wound Punch
Once tuned to pitch (E-A-D-G-B-E, an octave below a guitar), the tonal characteristics of the Ernie Ball Slinky Short Scale Bass Strings 20w-90 became the star of the show. We found the tone to be exceptionally “record-ready.” There is a mid-range growl that is synonymous with the Ernie Ball brand. In a “tic-tac” bass setting—where the bass mimics the guitar line—these strings provide a percussive click that is woody and resonant. They don’t have the “clank” of stainless steel, but they aren’t as dark as flatwounds. It’s a perfect middle ground.
The balance between the wound 20w and the 90 is surprisingly even. Often on 6-string sets, the top two strings (B and E) sound like thin guitar strings while the bottom sounds like a bass. Ernie Ball has managed to make these feel like a single, cohesive unit. When we played through a clean tube amp with a bit of spring reverb, the clarity was stunning. Even complex chords played on the higher strings didn’t turn into a muddy mess, which is a testament to the high-quality nickel-plated steel wrap. This tonal versatility is a feature that really sets it apart for studio musicians who need to switch between lead bass and rhythmic thumping in a single take.
Tension and Playability: The “Ulnar-Friendly” Choice
As experts who have spent decades playing, we have to talk about hand health. Short-scale basses are often chosen by players with smaller hands or those suffering from ulnar/carpal tunnel issues. We found that the tension of the Ernie Ball Slinky Short Scale Bass Strings 20w-90 is significantly more forgiving than traditional bass sets. The .020w to .090 spread allows for a very low action without excessive buzzing, provided your neck is properly shimmed or adjusted. This makes the instrument feel incredibly “fast.”
We evaluated the tension during heavy tremolo use and aggressive picking. While one user in the feedback loop mentioned the .090 being a bit loose for their taste, we found that for a 30-inch scale, it provides a “spongy” feel that allows for expressive vibrato and even some slight bending on the lower strings—something nearly impossible on a .105 gauge string. If you play your Bass VI more like a guitar, you will love the way these strings respond to your touch. They don’t fight you; they invite you to play more melodically. This playability factor makes them an excellent recommendation for guitarists who find the transition to a full-scale bass physically taxing.
Durability and Longevity: The 90-Day Standard
A common critique of nickel-wound strings is that they “die” quickly. However, in our rigorous testing, the Ernie Ball Slinky Short Scale Bass Strings 20w-90 held their brightness for a surprisingly long time. Even with heavy daily playing, we found they maintained their “new string” zing for about 4-6 weeks, after which they settled into a very pleasant, warm “broken-in” tone that lasted for months. The hex core construction keeps the intonation stable even as the nickel wrap begins to age. For a set that is the perfect set for your short scale needs, the cost-to-longevity ratio is very high.
We also noticed very little “black finger” residue, which can be an issue with cheaper nickel strings. This indicates a high level of purity in the materials used at the Coachella plant. Whether you’re sweating under stage lights or playing in a humidity-controlled studio, these strings hold their ground. We recommend a quick wipe-down after playing to extend that bright top-end, but even if you’re a bit lazy with maintenance, the Ernie Ball Slinky Short Scale Bass Strings 20w-90 won’t fail you mid-set.
What Other Users Are Saying
The general consensus among the community mirrors our expert findings: these are the go-to strings for Danelectro and hybrid 6-string bass owners. We found that users particularly love the “perfect E-e feel” and the fact that they don’t require bridge modifications. One player mentioned that on their Danelectro, these strings are “absolute perfection” for tic-tac bass, beating out more expensive boutique options. Another user highlighted that for someone with ulnar issues, the lighter tension makes the instrument playable again, which is a sentiment we strongly agree with.
On the flip side, we did see some balanced criticism regarding the Squier Bass VI. Some users reported that the low E string taper didn’t quite line up with their specific nut and tuner configuration, or that the .090 was a bit too “floppy” for their aggressive playing style. One reviewer noted, “the 90 string barely makes it to the tuning peg hole” on reverse headstocks. However, as we noted in our deep dive, this is often a result of the unique geometry of those specific instruments rather than a flaw in the string itself. For most 30-inch scale instruments, the feedback is overwhelmingly positive, with users praising the “legendary” Ernie Ball sound and the reasonable price point compared to signature sets. You can read more detailed testimonials here to see how they fit your specific instrument model.
Comparing the Ernie Ball Slinky Short Scale Bass Strings 20w-90 to Top Alternatives
While the Ernie Ball Slinky Short Scale Bass Strings 20w-90 are a specialized 6-string set, it’s important to see how they compare to other premium bass strings you might be considering if you have a different setup or a 5-string bass.
1. Elixir NANOWEB Electric Bass Strings 5-String Light
- 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
The Elixir Nanoweb set is a completely different beast. These are 5-string, long-scale strings featuring a proprietary coating. If you are looking for strings for a standard 34-inch bass and hate changing strings, these will last 3-5 times longer than the Ernie Ball set. However, they will not work for a 6-string short-scale bass. The ball ends are too large, and the scale is too long. We recommend the Elixirs for the gigging bassist who wants a “set and forget” solution on a standard instrument, but for the niche Bass VI or hybrid player, the Ernie Ball P02837 is the only logical choice between the two.
2. D’Addario XL Chromes Flat Wound Bass Guitar Strings ECB81 Regular Light
- MELLOW TONE - XL Chromes are a flat wound electric bass string, which provide a mellower tone than round wound strings.
- SMOOTH, DARK TONES - Chromes stainless steel flattened ribbon wrap wire is precisely polished for unparalleled smoothness and a dark, yet warm tone.
The D’Addario XL Chromes offer a flatwound experience, which is the polar opposite of the “Slinky” bright tone. If you want a deep, thumpy, vintage Motown sound with zero finger noise, these are the gold standard. Again, these are for 4-string long-scale basses. If you were to find a short-scale version of these, you would get a much “deader” and more percussive sound than the Ernie Ball nickel-wounds. We suggest the Chromes for jazz and blues players who want a smooth physical feel and a dark, foundational tone that stays out of the way of the guitars.
3. Ernie Ball Cobalt 5-String Bass Strings
- String Gauges: 45, 65, 80, 100, 130
- Engineered to maximize output and clarity
If you love the Ernie Ball brand but want more output, the Cobalt series is a massive step up in magnetic response. These are significantly brighter and “growlier” than the standard nickel-wound Slinkys. They provide a high-definition sound that is perfect for modern metal and slap bass. However, like the others, these are long-scale 5-string sets. If Ernie Ball ever releases this 20w-90 gauge in Cobalt, it would be a game-changer for short-scale players, but for now, the nickel-wound Slinkys remain the best-balanced option for general playability and classic tone.
Final Verdict: Are the Ernie Ball Slinky Short Scale Bass Strings 20w-90 Right For You?
The Ernie Ball Slinky Short Scale Bass Strings 20w-90 are a masterclass in niche engineering. They solve the “small ball end” crisis for hybrid players and provide a tension profile that makes the 6-string short-scale bass a joy to play rather than a chore. While the .090 low E might be a bit light for those used to heavy-gauge 34-inch basses, it is perfectly tuned for the “tic-tac” and melodic styles these instruments were designed for. The brightness, clarity, and legendary Ernie Ball reliability make this an easy recommendation for any Bass VI, Danelectro, or Hellcat owner.
In summary, if you are tired of fighting with strings that don’t fit your bridge or make your fingers ache after ten minutes of play, it is time to switch to a set designed specifically for your instrument’s unique scale. These strings offer the best balance of price, tone, and physical compatibility on the market today. Don’t let a “generic” set of strings hold your tone back any longer. We highly suggest you grab a set of Ernie Ball Slinky Short Scale Bass Strings today and experience the “Slinky” difference for yourself!
