Jack's Guitarcheology is an official Ernie Ball dealer.
From Ernie Ball:
Silver Slinky Strings are the result of an extraordinary partnership between Ernie Ball and John Mayer. They feature a never before offered gauge combination along with Reinforced Plain Strings (RPS) for added tuning stability and durability. Each string has been meticulously engineered with specific gauges and core-to-wrap ratios to meet John’s exacting standards, delivering the perfect balance of tone and tension.
This never before offered combination consists of 10.5, 13.5, 17.5, 27, 37, and 47 gauges.
