Power Groove Pure Nickel line from S.I.T. Strings 

The S.I.T. (Stay In Tune) Strings Company has expanded its Power Groove Pure Nickel line of electric guitar strings to include various hybrid sets and heavier sets.

The two newest sets will include a Heavy Bottom .010-.052 and a heavier .012-.052 with a wound third string. While these strings were originally designed  for vintage guitars, more players are starting to use them for modern guitars. More options, such as a 7-string set, will be available later this year.
