Roundwound cryogenically treated nickel plated steel. Max out Boomers experience with our Sub-Zero Bass Boomers series. GHS Sub-Zero Bass Boomers are cryogenically treated in a computerised system with liquid nitogen, taking them down to a temperature of minus 300 degrees Fahrenheit, and then gradually restoring them to room temperature. This treatment improves the dimensional stability of the strings, keeping them in tune, while increasing resistance to corrosion.
