The MMTW is a direct replacement for the Music Man large profile bass pickup. Inside the MMTW are two independent pickup tones. One is a ceramic and steel humbucking pickup that gives players an incredibly rich bass tone. The wide spread bobbins combined with a large coil surface gives this mode a big bass sound. In the single coil mode, via a push/pull pot, the MMTW becomes J pickup, with detailed presence and a strong mid-range character.
