Humcancelling 6 String Bartolini® P4 Sized Pickup Set
This is a modern design dual coil humbucking pickup.
Pickups like these are usually found on very high end basses. They use Alnico III magnets and the traditional bi-pole layout with two poles per string.
It's almost like two Jazz Bass® style pickups in one cover.
This pickup is available in two different versions. One is designed to be wired in parallel, and the other is designed to be wired in series. The reason we do this is that a pickup that is made to sound good wired parallel will usually be too hot and dark sounding if wired in series. So, we put less wire on series dual coils than parallel dual coils.
In general, a pickup wired in series will have a fuller and fatter midrange with a subdued high end than a pickup wired in parallel, which will typically have more highs and a deeper low end with a cleaner midrange. Series pickups also have more output than parallel pickups. Parallel pickups generally are a better choice for a split-able installation as there will not be the gain loss associated with series style pickups.
This pickup features a series wind.
