The 45DC, 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 45DC, we have succeeded in getting this extended range by utilizing an ultra low noise, low-impedance internal preamp, paired with ceramic loaded dual parallel coils that result in an extremely versatile unit that can be used for just about anything from the cleanest highs right down to the dirtiest growling lows. This model uses an extended housing that is 4.5 inches (115mm), perfect for most six string spacings. See why musicians worldwide are raving about their DCs!
