The size, type and configuration of magnets in a pickup all affect the sound it pickup produces. So does the type of wire, including its thickness, the type of insulation, how it’s wound around the bobbin and how many times it’s wrapped around. This article goes into this in more detail but basically the more turns contribute to a louder perceived output but less high frequency content, while fewer turns equal less power but more clarity. Different magnet types also affect the tone. The most commonly-used magnet family is Alnico, which is short for ‘aluminium/nickel/cobalt.’ Alnico III is the weakest: its low magnetic pull makes it a popular choice for neck pickups, where its bold attack allows it to speak clearly. Alnico II’s tone is relatively soft and clear and isoften described as sweet or singing.
Alnico V is more powerful and edgy, and is at the heart of one of our most sought-after pickups, the JB, which has lots of ‘hot-rodded’ power. And Alnico VIII blends certain sonic elements of ceramic and Alnico V magnets. For instance, compared to an Alnico V, Ceramic gives you maximum tightness, aggressive treble punch and a midrange scoop, and it’s also more compressed-sounding. Alnico VIII is also tighter and punchier than Alnico V, but with similar warmth and harmonics.
