D'Addario XL ProSteels Bass Guitar Strings 6-String Super Long Scale

In this review the D'Addario XL ProSteels EPS170-6SL set is examined for 6-string players who want a bright, durable tone with extended low end. The bottom line: these are best for players seeking the brightest stainless-steel sound and strong pickup response, particularly when a pronounced high end and tight lows are required. The set's Super Long Scale 32-130 gauges add a low B and high C while keeping comfortable tension, and the review focuses on tone, durability, feel, and how well they hold intonation.

Key Features

• Bright stainless-steel wrap: produces a highly present, piano-like treble that cuts through mixes and reacts strongly with magnetic pickups.
• Hex-core construction: ensures consistent intonation and a predictable feel across all six strings for reliable tuning stability.
• Super long scale set: the extended scale length supports the 32-130 gauges for balanced string tension and clear low B response.
• Regular light gauge: offers a mix of playability and full tone so players get defined lows without overly stiff tension.
• Durability and value: stainless wrap and high carbon core combine for long life and sustained tone, giving good value for players on a budget.
• Made in the USA: manufactured to exacting specs at D'Addario's New York facility for consistent quality.

Who It's For

Players who need a bright, cutting bass tone across six strings will appreciate these strings: session players, metal, rock, and jazz musicians who rely on harmonically rich highs and tight lows for clarity. The added high C and low B make this set suitable for 6-string arrangements that require both extended upper range and deep low fundamentals.

Those who prefer ultra-smooth-coated strings or a warmer, vintage steel sound might look elsewhere; some players report the feel is not as silky as coated sets. Also, if you play exclusively fingerstyle with a softer, mellow tone in mind, a nickel or flatwound alternative could be a better fit.

Pros & Cons

Pros

• Very bright, articulate highs that enhance pickup response and presence.
• Tight, focused low end that supports clear low B notes even on extended scale lengths.
• Solid durability and value, with many users noting long-lasting tone under regular use.
• Consistent intonation and feel from D'Addario's hex-core design.

Cons

• Some players find the surface feel less smooth than coated or different alloy strings, which can affect playability preferences.
• Brightness may be too pronounced for players seeking a warmer, vintage bass voice.
