the Big Splits are described as "Full fat bottom, solid thick mids, and clean clear highs"
the Fat Stacks: "These pickups have a tone reminiscent of a J style single coil, but they are bigger and bolder. Full range with a present but pleasant high end response. These pickups have a great deal of midrange detail and fullness. Due to the naturally lower output of this design, these pickups can sometimes benefit from a preamp with 3 or more db of gain."
