BlackSmith electric bass strings are made with the finest materials and manufactured using state-of-the-art automatic servo controlled winding equipment. USA made stainless steel ensures a longer lasting string with increased sustain and much brighter tone than traditional nickel round wound strings. Our proprietary computer controlled winding technology produces strings with a very consistent wrap surface and even tension, resulting in stable tuning, accurate intonation, and superior playability. The Micro Carbon Shield coating, AAOT, prevents oxidation and dirt build-up on the wound strings and are designed to last even longer than our flagship, AOT (Anti-Oxidation Technology) strings. With BlackSmith Micro Carbon shield coated bass guitar strings, you will experience the perfect balance of consistency, tone, durability, and performance.
