Ernie Ball Slinky Nickel Wound 6-String Electric Bass Strings (.032–.130) review: the classic-tone alternative to Cobalt

Ernie Ball's Slinky Nickel Wound Long Scale 6-String Electric Bass Strings run .032 to .130, nickel-plated steel wrapped around a hex steel core. It's the nickel counterpart to the Slinky Cobalt 6-String Electric Bass Strings already reviewed on CYS: same gauge, same 6-string spread, different wrap alloy. Ernie Ball's own product page keeps the description simple, each string "produces a bright, balanced tone," and adds a build spec specific to this 6-string gauge that most retailers don't publish: designed for a 34 inch scale bass, with an overall string length of 48 inches and the taper beginning at 37 1/4 inches.

This set also closes the last open gap in Ernie Ball's nickel-wound bass catalog on CYS. The 4-string spread (Extra through Beefy Slinky) and the 5-String Regular Slinky Bass already had pages; this 6-string gauge, SKU P02838, was the one missing entry, and the direct nickel sibling to the Cobalt 6-string bass CYS shipped earlier the same day.

Ernie Ball's own nickel and Cobalt product pages both list this identical .032 to .130 six-string gauge over a hex steel core, just wound in different wrap wire, nickel-plated steel here versus a cobalt alloy on the other set.

For the fuller measured breakdown of Cobalt vs nickel voicing (output dB, brightness curve, bend feel), see Cobalt Slinky vs nickel Slinky: the voicing difference, explained. That page covers Ernie Ball's guitar strings, but the same wrap-wire logic carries over to bass: nickel's rounder, warmer low end versus Cobalt's tighter, more defined one. On a 6-string bass the low B is doing more work in a mix than on a 4-string, since it's the only string below E, so the alloy's low-end character is worth weighing before you buy.

Ernie Ball ships nine nickel Slinky bass gauges across three string counts. This is the only one built for 6-string:

• 4-string, lightest: Extra Slinky Bass, .040–.060–.070–.095.
• 4-string, light: Super Slinky Bass, .045–.065–.080–.100.
• 4-string, hyper: Hyper Slinky Bass, .040–.060–.080–.100.
• 4-string, hybrid: Hybrid Slinky Bass, .045–.065–.085–.105.
• 4-string, standard: Regular Slinky Bass, .050–.070–.085–.105.
• 4-string, heavier: Power Slinky Bass, .055–.075–.090–.110.
• 4-string, heaviest: Beefy Slinky Bass, .065–.080–.100–.130.
• 5-string, standard: 5-String Regular Slinky Bass, .045–.065–.080–.100–.130.
• 6-string, this set: Slinky Nickel Wound Long Scale 6-String Bass (SKU P02838), .032–.045–.065–.080–.100–.130, the only 6-string gauge in the nickel line.

The Cobalt side of this same family tree (also nine gauges) lives on the Cobalt 6-string bass page. Full extended-range roster: 5-string and 6-string bass players.

No documented artist plays this exact nickel 6-string set on the record CYS has sourced. Dream Theater bassist John Myung's Music Man signature lineup is a 4-string (the John Myung 4) and this 6-string Bongo, no 5-string model, and Music Man's own specifications table lists the Bongo 6's factory strings as the Cobalt version, not this nickel set.

So a player chasing Myung's exact 6-string factory spec wants the Cobalt 6-string, not this page. A player who already prefers nickel's warmer, rounder voicing and wants a budget-friendly 6-string without switching alloys is exactly who this set is for.

Thundercat is another documented 6-string bassist CYS covers, though his instrument is strung with Dean Markley SR2000 Medium Custom, a different brand entirely.

• Budget-conscious 6-string players. This set costs less than the Cobalt equivalent at the identical .032 to .130 gauge.
• Players who already run nickel and want to keep the voicing consistent while stepping up from a 4-string or 5-string Ernie Ball set to a 6-string instrument.
• Traditional, rounder low-end tone. Nickel's warmer character sits well under a dense mix where Cobalt's extra brightness can compete with guitars for space.

• Players chasing maximum output and articulation. Ernie Ball's own Cobalt 6-string claims a stronger magnetic relationship with pickups and a tighter low end; nickel is the rounder, lower-output baseline by comparison.
• Maximum string life. Nickel Wound is uncoated, the same wear curve as any uncoated roundwound; Ernie Ball's coated longevity line is Paradigm, not this family.
• Drop-tuned 6-string setups below B standard. The .130 low string is built for B standard; Ernie Ball ships no heavier 6-string nickel option, so a lower tuning means custom singles instead.

The thin .032 high C is the string most likely to snap if a nut slot is cut rough or too narrow, the same install caution that applies to the Cobalt 6-string at the identical gauge. Break-in runs about the same as any fresh nickel roundwound: 15 to 20 minutes of playing before the top end settles. Stretch each string, pull up gently a few times, retune, and repeat before a gig or session, paying extra attention to the high C until it holds pitch.

Slinky Nickel Wound Long Scale 6-String Electric Bass Strings is Ernie Ball's budget, classic-tone answer for 6-string bass: the identical .032 to .130 gauge as the Cobalt 6-string, in nickel-plated steel instead of cobalt alloy, for a lower price.

If output and brightness matter more than price, step up to Cobalt, the set with John Myung's actual documented Bongo 6 factory spec behind it. If you want a warmer, rounder low end and a lower price at the same gauge, this is the set.
