Kerly Music Strings are tightly wound using the finest metals, on monitored and maintained machines to ensure quality winding. We enhance the state of the regular strength by exposing them to drastic temperature changes to create added benefits.

Our US patent number 7,402,737 tempering process exposes them to minus 320 Fahrenheit +350°F for up to 48 hours. This treatment uses liquid nitrogen to blast the strings with extremely cold air and his met by intense heat over a long period of time which provides added qualities such as strength, crystal tone, increased durability and corrosion resistance. Tuning is less frequent, and smoother surface feel is created with stellar bendability.

All Kerly products are treated with this process - Kerly Kues, Sinister Strings, Earth tones, Wicked Wire, Death Valley, Kerly Bass, Millennia and 50’s Nickel.

Kerly Strings is the pioneering string company that started the discussion that the strings are all about metal type and quality and how it interacts with your fingers. Prior to our introduction, other companies did not want to discuss ‘durability’ or how inferior alloys do not provide a guitarist with a reliable source of strings. It is a fact that Kerly strings are the strongest and most durable string on the market due to our unique process. When we launched our brand in 2003, we were the very first manufacturer to sell our strings in foil barrier pouches to prevent oxidization. Since then, all companies have followed suit. From winding, tempering, and packaging, we maintain a duty to the guitarists who truly relies on their set of strings for maximum endurance on stage, in the studio, or just rehearsing in the bedroom.
