Equipped with a humbucker and a single-coil pickup as well as an extra string and an active preamp, the Sire Marcus Miller Z7 5-String Bass can handle anything you throw at it. The mounted Marcus Heritage-3 preamp features a 3-band EQ and a Blend pot so you can seamlessly mix up the sound of the Sire Standard MM humbucker and the Sire Premium J single-coil, while the modernly contoured body is made from alder to ensure a balanced foundation sound and a satisfying weight. The Marcus Miller Z7 5-String: Comfy Playing Feel Aside from a broad sonic spectrum, the Marcus Miller Z7 5-String offers masses of playing comfort. As well as 22 extra-durable, stainless steel medium jumbo frets and a flat 12-inch radius, Sire has gone for an edgeless maple fretboard for a rounded feel and ample grip. Another welcome perk is the bone nut, which grants increased tuning stability and boosts the resonance, completing an effortlessly-playable bass that doesn't cost the earth.
