Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Ernie Ball Power Slinky Cobalt Bass Strings (55-110).

Setup and maintenance

  • It's recommended to wipe down cobalt strings with alcohol or WD40 to remove excess machine oil, preventing a metallic smell during initial use.

    Source
  • A user found that using lighter gauge B strings, like a .110, provided better sustain and tonal consistency across all strings when tuning a 34" scale bass to BEAD.

    Source
  • Regular tuning between E standard and drop C can be managed without truss rod adjustments, especially with a stiff neck.

    Source
  • A 110 gauge string may require nut slot widening on some basses, particularly those with narrow slots like certain Fender models.

    Source
  • Adjusting the truss rod by less than 1/4 turn counterclockwise is suggested for minimal relief change when tuning down.

    Source

User experience

  • Bassists who prefer looser strings for melodic play found that lighter gauge strings offered a beneficial tonal character for genres like jazz and prog.

    Source
  • A player using Ernie Ball Power Slinkies noted that downtuning the E string to B on a Stingray resulted in perfect intonation and improved sustain up to the 17th fret.

    Source
  • Cobalt flats are described as having a slightly "grabby" feel initially, with machine oil residue that should be wiped off before installation.

    Source
  • Power Slinkys may require more effort to play compared to lighter gauge strings, particularly noticeable during extended playing sessions.

    Source

Comparisons

  • Compared to heavier gauge sets, a .110 B string on a 34" scale bass provided a more satisfying tonal match with the other strings, improving overall playability and sound consistency.

    Source
  • Compared to GHS Pressurewounds, cobalt flats are less polished and have a distinct feel that might not be as smooth as other flatwounds like LaBellas.

    Source

Use cases and applications

  • Lighter gauge B strings, like a .110, can surprisingly handle lower tunings without becoming floppy, challenging the typical belief that heavier gauges are necessary for this purpose.

    Source
  • Users report that the strings maintain brightness longer on basses with Kent Armstrong Claymore pickups compared to other pickup types.

    Source
  • Cobalt flats are praised for a high output and bright sound, almost similar to roundwounds, making them suitable for aggressive styles like slap bass.

    Source
  • Power Slinkys are suitable for tuning down to B standard, providing a stable and consistent tension for lower tunings.

    Source

Features and functionality

  • Users mentioned that the number of wraps on a string affects clarity and intonation, with fewer wraps generally yielding a clearer tone.

    Source
  • The cobalt alloy outer wrap is noted for being more magnetic than steel or nickel, contributing to the strings' higher output.

    Source

Mods and upgrades

  • Some players add hex nuts behind the bridge for extra tension when detuning, particularly useful for maintaining intonation stability during heavy play.
