GHS Sub-Zero Boomers Nickel-Plated Steel 9-46 Electric Guitar Strings, Custom Light
Sub-Zero Boomers are Roundwound Cryogenically Treated Nickel-Plated Steel Strings. This basically means they are Boomers that have been enhanced with the DCT cryogenic freezing process.
The strings treated in a computerised system with liquid nitrogen, 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.
