The IUSO SPBA54QD handcrafted pickup set consists of two quad coil humbuckers with exposed Alnico 5 poles, specifically designed for 4 strings basses. Each pickup is equipped with 4 conductor wires that provide various wiring options, including series/parallel or single coil hum-canceling.

By utilizing the inline split coil mode, you can achieve the distinctive jazz bass character and benefit from background noise cancellation. Opting for the parallel mode softens the sound, adding a smoother tone to your bass. When connecting the pickups in series, the character becomes even more aggressive and powerful, allowing you to unleash greater sonic strength.

Thanks to this configuration, the pickups set offers remarkable sound versatility, enabling musicians to express their creativity and achieve the desired tone during their performances. You’ll be able to adapt your bass sound to different musical situations, providing a wide range of expressive possibilities.
