The MMHZ is a direct replacement for the original Music Man bass pickup. This pickup is passive (without internal pre-amp) and features a dual-coil design for low noise and plenty of output. The MMHZ housing is directly compatible with EMG's entire active MM pickup line. All feature the CS design (ceramic and steel). The CS design has the punch and fullness of the older passive designs along with added brightness for a better-defined tone. EMG's Active CS Series pickups feature the same construction and have proven popular among bass players. The five pin connector allows multiple wiring combinations so you can get both dual-coil and single-coil tone with simple switching. Each pickup is fully shielded for a minimum of noise.
