GHS offers more types of bass strings than any other brand in the JustStrings.com catalog. Per GHS: "GHS Pressurewound Bronze strings are an exciting development. The final cover is run through precision rollers during the winding process, slightly flattening the wrap. This process results in the first phosphor bronze bass string that does not have harsh and abrasive overtones and finger noise, just a smooth mid-focused sound. Pressurewound Bronze are also designed in such a way that they also work well with electric basses." GHS has been manufacturing strings since 1964 and builds all the machinery used to make their strings in house. String winders are computer managed for superior accuracy, but the human touch maintains quality. GHS prides itself on the excellence of their materials and the consistency of their manufacturing. Musicians worldwide rely on the quality and reliability of GHS strings.
