GHS' Nickel Rockers range features a premium round pure nickel wrap wire wrapped around a central round core.  The outer round wound windings are then flattened to create a semi-flat wound string, somewhere between a round wound and flatwound set.   From a playability standpoint, this creates a set with a smoother feel and a warmer tone yet still retaining some of the clarity often associated with standard round wound strings.

The Nickel Rockers have been a staple set for GHS for many years and even the great Stevie Ray Vaughan and Eric Johnson being avid users of these particular strings in the past.  

All GHS single strings are packed in their airtight Nitro-Packs ensuring the strings stay free of corrosion, tarnish and rust and remain as fresh as possible. 

Here's what GHS say about these strings;

"A high quality core wire is wrapped with a round, pure nickel cover that is slightly flattened by computer-controlled precision rollers in the winding process. The result is a semi-flat string that has a warm but articulate tone, which feels great under the fingers."
