Buying Guide

Understanding String Gauges

When selecting strings for a 7-string guitar, the first feature we consider is the string gauge. This refers to the thickness of the strings, which impacts playability and tone. Typically, a set will range from a thinner high E to a thicker low B string.

  • Lighter gauges offer easier playability and a brighter tone.
  • Heavier gauges provide more volume and sustain but require more finger strength.

Material and Tone

Different string materials produce distinct tones:

  • Nickel-plated steel is popular for its balanced tone.
  • Stainless steel delivers a brighter sound and is resistant to corrosion.
  • Cobalt offers a stronger magnetic relationship with pickups, enhancing output.

String Coatings

Coated strings are treated to extend lifespan by protecting against factors like moisture and oils from the fingers.

  • Pros:
    • Longer life
    • Consistent tone over time
  • Cons:
    • Often more expensive
    • Some players feel a difference in texture

Tension and Tuning Stability

We want our strings to maintain tension and tuning stability. This is crucial for 7-string guitars, which often handle lower tunings.

  • Thicker core wires and denser materials maintain tension better.
  • Wound strings can enhance tuning stability at lower pitches.

Core Types

Strings come with varying core shapes:

  • Round cores tend to feel more flexible.
  • Hex cores offer more tension and a tighter feel.
Lighter GaugesEasier playability, brighter toneLess volume, might feel too slinky
Heavier GaugesMore volume, sustainRequires more finger strength
Coated StringsLonger life, consistent toneMore expensive, different texture
Round CoreGreater flexibilityMight lack tuning stability
Hex CoreEnhanced tension, tighter feelMight be less flexible for some

Through careful consideration of these characteristics, we find the best strings suited to our individual needs and preferences.
