Technical Composition

The EPS170-5 set is constructed using a specialised stainless steel wrap wire wound over a high-carbon steel Hex-Core. This hexagonal core design is a signature D'Addario feature, intended to ensure the wrap wire grips the core tightly for improved tuning stability and accurate intonation. The nickel-free composition of the ProSteels series provides a distinct tactile feel and a high level of magnetic response compared to traditional nickel-plated sets.

Tonal Characteristics

ProSteels are marketed as D'Addario's brightest and most corrosive-resistant bass strings. The EPS170-5 set delivers a 'super-bright' tone characterized by crisp, harmonically rich highs and a tight, focused low end. This frequency response is designed to provide maximum definition, which is particularly beneficial for the low B-string on 5-string instruments, preventing the common issue of 'muddiness' in lower registers.

Playability and Gauge

As a 'Light' gauge set, the string diameters are .045, .065, .080, .100, and .130. This specific configuration strikes a balance between physical power and ease of play. The lower tension of the light gauge allows for easier string bending and a faster response, while the stainless steel wrap provides a smooth, consistent feel under the fingers for the performer.

Manufacturing and Packaging

Produced in the USA, these strings undergo strict quality control to maintain consistency across batches. D'Addario employs environmentally friendly packaging, using recyclable VCI (Volatile Corrosion Inhibitor) bags that protect the strings from oxidation while in storage. Additionally, the packaging includes a unique code for the D'Addario Players Circle rewards programme, allowing users to earn points for future purchases.

Target Audience and Applications

The EPS170-5 is suited for bassists who require a modern, aggressive tone that cuts through a dense mix. They are highly effective for genres such as metal, prog-rock, and funk, where slap techniques and clear articulation are paramount. Because they are designed for long-scale instruments, they fit the majority of standard 5-string basses currently on the market.
