Few things have a bigger impact on the quality of a bass guitar sound than the strings. This fact is particularly pronounced if the strings have been used for some time. As bass guitar strings age, their sound becomes dulled by corrosion, oxidization, and good ol' grime buildup. You might not notice the gradual decline in sound, but rest assured: it's happening. When you change to a new set of strings, you may be stunned at the sudden improvement in sharpness and clarity of tone.

In choosing electric bass guitar strings, the name on the label doesn't matter as much as the type of string. There are many bass guitar string brands--including Alembic, D'Addario, GHS, Elixir, and RotoSound, to name a few--but the technologies used to produce them are similar. Since differences in tone set one string type apart from another, it is useful to know about the types of strings available and the effects they produce. For bassists, the challenge is to find the right type of string to suit the style.

First, let's look at nickel-wound strings. As the name implies, these strings are constructed with a nickel-plated steel wrap. Many rock bassists prefer nickel-wound strings, as they tend to deliver a clear, captivating tone.

Another type of string you will find on the market is stainless steel strings. You may want to choose this type for two principal reasons. First, they feel smooth to the finger, making them ideal for long gigs and marathon studio sessions. Second, finger noise is reduced with stainless steel, a preference in sound for some bassists.

Chrome, flat-wound bass strings are popular among professionals for their deep, smooth and pounding tone. Construction-wise, these strings are specially wound and polished to give the effect of a smooth surface. Another variation on string winding comes in the form of half-round bass strings, which are ground down partially, providing a compromise between round-wound and flat-wound strings. This half-round treatment provides some of the brightness of round-wound strings and some of the comfort and depth of tone of the flat-wounds.

The shape of the core wire also has an effect. Round cores can have more mass than hex-core strings, for example, and can provide more cohesive contact between the core wire and the outer wrap, producing a long-lasting bass string with powerful bass tones.

Special treatments and processes are also applied to bass strings to enhance their performance and longevity. For example, some manufacturers treat strings in a liquid nitrogen bath, which is claimed to extended string life and help the strings stay in tune over long periods. Other strings feature chemical coatings, which manufacturers claim makes them deliver marvelous, low tones mimicking those of the piano.

In the final analysis, the type of string you choose will depend on a lot of factors both personal and technical. Hopefully, this survey of the wonderful world of bass strings has helped ease the task of choosing the right style to suit your sound.
