The 40P5 design incorporates our P5 model into an extended series housing that has two offset coils that result in more low end with brilliant highs. It is intended for 5-string models that have a standard string spacing and uses short, squat coils that have very little resistance and plenty of inductance. Ceramic magnets are used to add clarity. The 40P5 has a natural presence, powerful lows, punchy midrange, and superior definition. This pickup uses a 40 Extended housing that is 4 inches (102mm).
