The Sire V7+ A4F/BK is a fretless 4-string J-style bass guitar from the Marcus Miller V7 2nd Gen series, finished in timeless black. This bass is designed for musicians seeking the warm, smooth tone and expressiveness of a fretless instrument without sacrificing modern functionality. Thanks to the combination of Marcus Super-J Revolution pickups and the advanced Marcus Heritage-3 preamp, this bass offers an impressive tonal range with complete control over your sound, in both active and passive modes.
The body is crafted from North American alder and delivers a powerful, balanced tone with a firm midrange. The hard maple neck features an ebony fingerboard with beveled edges for optimal playing comfort, even during complex runs and slides. The Marcus Heavy Mass bridge provides rich sustain and tight tone definition, while the natural bone nut enhances resonance and clarity. This fretless version is ideal for advanced players seeking a dynamic and expressive bass for studio or live performances.
