D'Addario EXL120 Nickel Wound Super Light 9-42 (3-Pack)
The D'Addario EXL120 3D is a three-pack of nickel-wound electric guitar strings featuring a 'Super Light' gauge of .009 to .042. Renowned for their high flexibility and biting tonal character, these strings are constructed with a high-carbon steel hexagonal core to ensure durability and stable intonation.

Background and Design
The EXL120 series represents one of D'Addario's most popular electric guitar string lines, specifically designed to offer a balance between comfort and performance. This three-pack variant, identified as the 3D pack, is marketed as a cost-effective and environmentally conscious way for guitarists to maintain their instruments. The strings are manufactured in the USA using a precision-drawn high-carbon steel core.
The defining characteristic of these strings is the hexagonal core shape. Unlike traditional round cores, the hex core provides a more secure mechanical bond with the nickel-plated steel wrap wire. This design choice is intended to improve durability and prevent the wrap from slipping, which helps maintain tuning stability over extended periods of play.
Tonal Characteristics
D'Addario describes the tone of the EXL120 as 'distinctively bright.' The nickel-plated steel wrap contributes a crisp, biting high-end that is suitable for cutting through a band mix. Despite the emphasis on brightness, the strings are engineered to provide accurate intonation across the fretboard.
The Super Light 9-42 gauge provides less tension compared to standard sets, which typically results in a more resonant top-end and a lighter feel. This makes them particularly effective for genres that require clarity and a sharp attack, such as rock, pop, and blues.

Construction and Materials
The EXL120 sets are composed of two primary materials:
- High-Carbon Steel: Used for the hexagonal core and the plain strings to ensure maximum tensile strength.
- Nickel-Plated Steel: Used for the winding on the E, A, and D strings, providing the magnetic properties necessary for electric guitar pickups while offering a smoother feel than pure stainless steel.
The packaging is a significant feature of the 3D pack. D'Addario utilizes environmentally friendly, corrosion-resistant packaging. This sealed environment protects the strings from oxygen and moisture, ensuring that the strings remain factory-fresh and free from oxidation until they are opened for installation.
Suitability and Comparison
The Super Light 9-42 gauge is ideal for players who prefer low tension for easier string bending and vibrato. It is often recommended for beginners who are still developing finger strength, as well as experienced lead guitarists who perform technical solos.
When compared to alternatives such as the Ernie Ball Regular Slinky (10-46), the EXL120 offers a lighter touch and a brighter sound. For those seeking signature tones, the Ernie Ball Tim Henson Signature (9.5-46) provides a hybrid tension that sits between light and medium, whereas the EXL120 remains a traditional light set. Compared to premium offerings like the Ernie Ball M-Steel, the EXL120 focuses on a classic nickel-plated feel and value for money through its multi-pack format.

Frequently asked questions
- What is included in the D'Addario EXL120 3D pack?
- The pack contains three individual sets of EXL120 Super Light electric guitar strings. Each set includes six strings with gauges ranging from .009 to .042.
- What are the specific string gauges in a 9-42 set?
- The set typically consists of .009, .011, .016 (plain), and .024, .032, .042 (nickel wound). This configuration is standard for a 'Super Light' tension.
- What material is used for the winding?
- The wound strings feature nickel-plated steel wrapped around a high-carbon steel core. This provides a balance of magnetic output and brightness.
- What is the benefit of a hexagonal core?
- The hexagonal core allows the wrap wire to grip the core more effectively. This improves durability and ensures better intonation and tuning stability.
- Are these strings suitable for beginners?
- Yes, the 9-42 Super Light gauge is highly recommended for beginners. The lower tension makes the strings easier to press down and bend compared to heavier gauges.
- How does the packaging protect the strings?
- D'Addario uses environmentally friendly, corrosion-resistant packaging that seals the strings. This prevents air and moisture from reaching the metal, ensuring they don't rust before use.
- Can these strings be used on an acoustic guitar?
- While they will physically fit, nickel-wound strings are designed for electric guitar pickups. They will sound very thin and quiet on a traditional acoustic guitar.
- What kind of tone do these strings produce?
- These strings are known for a bright, biting tone. They provide excellent clarity and high-end presence, making them versatile for many musical genres.
- How long do these strings typically last?
- Lifespan varies by player acidity and usage, but the high-carbon steel core is designed for long-lasting performance. The nickel plating also resists corrosion better than plain steel.
- Is a three-pack better value than a single pack?
- Yes, the 3D pack is typically more cost-effective per set than buying single packs. It is priced around £18, offering a significant saving for frequent players.
- Where are D'Addario EXL120 strings manufactured?
- These strings are manufactured in the USA by D'Addario, ensuring high standards of quality control and precision during the drawing and winding process.
- Are these strings good for heavy metal tuning?
- They are generally too light for significantly detuned music (like Drop B). However, for standard tuning or E-flat, they are excellent for fast lead playing and high-speed solos.
