Ernie Ball Everlast Coated Phosphor Bronze Acoustic Strings - Medium Light (12-54)

Born from an exclusive partnership between Ernie Ball and legendary guitarist John Mayer, Silver Slinky Strings represent a breakthrough in string engineering. These signature strings showcase a completely new gauge combination that has never been available before, developed through meticulous collaboration to meet Mayer’s exacting standards for both tone and playability.

Each string incorporates custom gauges and precisely calculated core–to–wrap ratios, formulated using specially tailored Slinky recipes that align with John Mayer’s musical preferences. The inclusion of Reinforced Plain Strings (RPS) technology provides superior tuning stability and extended durability, ensuring consistent performance across extended playing sessions.
