What is the gauge of the XTAPB1152 set?

The set is a Custom Light gauge, measuring .011, .015, .022, .032, .042, and .052 inches.

What core material is used in these strings?

These strings feature high-carbon NY steel cores, which provide greater strength and break resistance than standard steel.

How does the XT coating differ from other coated strings?

The XT series uses a microscopic coating treatment on every string in the set, designed to feel like an uncoated string while protecting against corrosion.

What is the benefit of the 'Fusion Twist' ball end?

The Fusion Twist technology prevents the string from slipping at the ball end, which significantly improves tuning stability and strength.

How much better is the tuning stability compared to standard strings?

D'Addario's testing indicates that these strings stay in tune 131% better than standard, non-treated strings.

Are these strings stronger than standard acoustic strings?

Yes, the manufacturer states that these strings are 42% stronger than standard strings due to the NY steel and coating process.

What kind of tone can I expect from Phosphor Bronze?

Phosphor Bronze is known for a rich, warm, and well-balanced tone that is suitable for a wide variety of acoustic playing styles.

Do the plain steel strings have the coating as well?

Yes, the XT treatment is applied to all strings in the set, including the plain steel high strings, to ensure uniform longevity.

How much do these strings typically cost?

A single set of D'Addario XTAPB1152 strings typically retails for approximately GBP 17.00.

Who is the 'Custom Light' gauge best suited for?

It is ideal for players who want a balance between the playability of light strings and the resonance of medium strings.

Can these strings be used on a classical guitar?

No, these are steel strings designed specifically for acoustic guitars with bridge pins. Using them on a classical guitar could damage the instrument.

How do these compare to D'Addario XS strings?

While both are coated, XT strings use a thinner microscopic treatment for a more natural feel, whereas XS strings feature a film coating for maximum possible longevity.

D'Addario XT Phosphor Bronze Custom Light (11-52)

The D'Addario XTAPB1152 is a set of coated phosphor bronze acoustic guitar strings designed for longevity and tuning stability. These strings utilise high-carbon NY steel cores and a microscopic water-repellent coating to preserve tone without sacrificing the natural feel of the string.

Overview and Construction

The D'Addario XTAPB1152 set is part of the XT series, representing a technical evolution in coated string design. These strings are constructed using high-carbon NY steel cores, which provide increased break strength and resilience compared to traditional tin-plated steel cores. A key technical feature is the 'Fusion Twist' technology at the ball ends, which reduces slack and improves the grip of the string on the bridge pin, leading to enhanced mechanical stability.

Longevity and Coating Technology

Unlike traditional coatings that can feel slippery or damp the vibration of the string, the XT series employs a microscopic treatment. This process covers every string in the set—including the plain steel strings—to protect against corrosion from sweat and environmental moisture. Manufacturer testing indicates that this construction makes the strings 42% stronger than standard industry alternatives, significantly extending the interval between required restrings.

Performance and Tuning Stability

Tuning stability is a primary focus of the XTAPB1152 design. Through the combination of the NY steel core and the Fusion Twist ball ends, these strings are engineered to stay in tune 131% better than standard strings. This makes them particularly suitable for players who use alternate tunings or perform in environments with fluctuating temperatures, where standard strings might frequently slip or stretch.

Tone and Playability

The Phosphor Bronze alloy provides a balanced acoustic response, offering a blend of warmth and brightness that is widely considered the industry standard for acoustic performance. Because the XT coating is extremely thin, the strings retain the tactile feel of an uncoated set while offering the lifespan benefits of a treated one. The 'Custom Light' 11-52 gauge provides a middle ground for players who find 12-gauge sets too stiff but want more projection than a standard 10-gauge set.

Comparison to Alternatives

Within the D'Addario ecosystem, the XT series sits between the uncoated EJ series and the fully coated XS series. Compared to other brands, such as the Ernie Ball M-Steel or Tim Henson Signature Slinkys, the XTAPB1152 is specifically voiced for the resonant requirements of acoustic guitars rather than electric output. While orchestral options like Thomastik Spirocore or D'Addario Helicore serve specific bowed instruments, the XT Phosphor Bronze is a dedicated solution for steel-string acoustic guitarists seeking durability.
