The 40CS, with its modern appearance is actually a product of 30+ years of design experience. Reproducing an extended range cleanly - both higher AND lower - taxes the abilities of conventional pickups. In the 40CS, we have succeeded in getting this extended range by utilizing an ultra low noise, low-impedance internal preamp, paired with parallel placed coils like the DC, but loaded with ceramic steel. The result is that the 40CS is much warmer as a result of the higher inductance of the steel, and thus has a smoother attack and a flatter high end. They are the most "Traditional" sounding of the group. This model uses an extended housing that is 4 inches (102mm), perfect for five string spacingﾒs. From Classic rock to Heavy Metal this pickup performs.
