Looking into manufacturing our very own custom formulated strings. Electric guitar only, treated nickel/steel, pre-made sets with calculated balanced tension for reduced neck stress , optimal feel, and consistent (with optional 7th string): Extra Light - .008 - .038 (.052) Light - .009 - .040 (.054) Regular - .010 - .045 (.060) Heavy - .011 - .050 (.065) Extra Heavy - .012 - .054 (.070) EDIT: All pre-made sets will have an optional "dropped" 6th string (thicker 6th string). Regular, heavy, and extra heavy sets would have an optional wound G (18w, 20w, and 21w respectively.) Also, custom sets up to as many as 12 strings, any size/combo you need! Pre-made sets would be priced around $6-$7 per set. Custom sets vary based on string choices and number of strings. Strings will be available sold individually as well. Any interest?? Future possibility: We're currently working on the math for balanced tension multi-scale sets. Edit: Added info asked in later threads.
