These are a proprietary Nordstrand design, born from the angled pole prospects of the bossman himself. The traditional bi-pole magnet layout was rotated 45 degrees, increasing the size of the traditional J style coil by 50%, making the coil wider and instigating the growth of a larger magnetic aperture, facilitating the capture of each string's unique harmonic characteristics. This results in a fatter tone that is somewhat reminiscent of a J style single coil. However, with the FS's stacked coil design, its tone is inherently darker, bolder, and fatter. The Fat Stack presents a range that cascades across the sonic spectrum, providing a present but pleasant high end, a detailed midrange, and full-bodied low end. Due to the naturally occurring lower output of its design, these pickups benefit greatly from a pre-amp with 3 or more db of gain.
