The Sire M7+ A5/TBL is a modern 5-string bass guitar from the second generation of the M7 Series, designed in collaboration with Marcus Miller. This Transparent Blue version combines an alder body with a solid flamed maple top, offering both a luxurious appearance and a balanced, powerful tone. The extended 35” scale length creates a tight low B string, while the comfortable C-shaped neck and Edgeless™ ebony fingerboard make for effortless playability.
Equipped with Marcus Pure-H Revolution humbuckers and the versatile Heritage-3 preamp, this bass delivers a rich and flexible tonal palette. The active/passive switch, three-band EQ with mid-range control, and pickup settings (series, split, or parallel) give you complete control over your sound. The robust hardware and modern finish make this a top-notch bass for professional and demanding bassists.
