NICKEL PLATED STEELpage/10/NW 10-46.jpg

Nickel-Plated Steel wound strings were introduced in the late Sixties and have become the most popular alloy for electric guitars and bass. Nickel-plated steel offer a balanced tone.

It took several years of trial and error to develop a proprietary string coating that resists tarnish and corrosion without compromising tonal quality.

 Stainless Steel wound strings became popular in the early  Seventies. Stainless Steel strings are the brightest  sounding strings and offer extended life to players who  have acidic hands.

PURE NICKELpage/10/PN 9-42.jpg

Pure Nickel wound strings were used exclusively on most guitars built in Fiftys and most of the Sixtys.

Pure Nickel has a slightly warmer tone than nickel-plated steel and is preferred by many blues artists.

 80/20 Bronze wound strings are often called old-school,  vintage and were the only alloy used to make acoustic  strings until the introduction of phosphor in the early  Seventies. 80/20 bronze wire is made from 80% copper  and 20% zinc.

80/20 bronze provides balanced highs and lows with a slight increase in mid-range that seems to make the notes cut-through a little more.

PHOSPHOR BRONZEpage/10/12-54.jpg

Phosphor Bronze wound strings were introduced in the early Seventies and have become the most popular acoustic string. Phosphor Bronze wire is made from approximately 92% copper, 7% zinc and 1% phosphorous. 

Phosphor Bronze provides nice highs and lows, and pleasant subtle overtones. Phosphorous is used to help reduce tarnish and corrosion.

 It took several years of trial and error to develop a  proprietary string coating that resists tarnish and  corrosion without compromising tonal quality. Curt and  his long time friend, a retired NASA chemist, developed a  completely new formula and procedure to coat the strings.
