The S features the same construction as the SA but replaces the Alnico magnet with ceramic. It has the equivalent output of the SA but the S features a brighter tone quality accentuated in the upper middle to high frequency response (similar to later model Strat pickups).Country artists such as Vince Gill prefer the EMG-S system because it can translate a playerís technique faithfully. Each S set includes a five-position selection switch, volume and tone controls, and output jack that's ready to install onto your pickguard with only three solder connections required.
