Sire V7 Alder-4 New Gen FL Tobacco Sunburst Fretless Bassguitar

Fretless Bass Guitar With Marcus Miller DNA

The Sire V7 Alder-4 New Gen FL Tobacco Sunburst is a 4-string fretless electric bass guitar designed in close collaboration with legendary bassist Marcus Miller. Built around a North American Alder body in the New Gen Jazz Shape, this fretless model delivers the smooth, vocal quality that defines the fretless J-bass tradition. The Sire V7 Alder-4 New Gen FL is the right choice for players who want the singing, woody character of a true fretless instrument without sacrificing modern electronics and playability refinements.

What Sets This Fretless Apart

Two details elevate this bass above typical fretless offerings in its segment. First, the Edgeless rolled-edge Ebony fingerboard removes the harshness of square fingerboard edges, giving the thumb and fingers a smooth path for glissandos and the characteristic fretless mwah. Second, the Marcus Heritage-3 preamp pairs a 3-band EQ with a dedicated Middle Frequency control, allowing the player to scoop or boost a precise midrange point rather than a fixed frequency — a feature usually reserved for higher-tier instruments.

Body & Tonewood — Alder Resonance

The body wood defines the fundamental character of any bass, and North American Alder is prized for its balanced, even response across the frequency spectrum. The Sire V7 New Gen uses this tonewood in the Marcus Miller Jazz Shape (New Gen), a contour refined for comfort during long sessions.

• Body Material: North American Alder — clear, full-range fundamental with tight low end
• Body Shape: Marcus Miller Jazz Shape (New Gen) — refined contour for seated and standing play
• Body Color: Tobacco Sunburst (TS)

Neck & Fingerboard — Playability Refinements

The neck profile and fingerboard geometry directly affect how the bass feels under the fingers, especially on a fretless where every position is felt rather than marked. Sire's New Gen C-shape sits comfortably in the hand, while the Edgeless rolled edges and Luminlay side dots give players both smooth slides and reliable stage visibility in low light.

• Neck Material: Hard Maple — bright, snappy attack that complements the fretless singing quality
• Neck Shape: C-Shape (New Gen)
• Scale Length: 864 mm (34") — standard long-scale feel with strong fundamental
• Fingerboard Material: Ebony with Edgeless rolled edges
• Fingerboard Radius: 241 mm (9.5")
• String Nut: Bone, 38 mm width — natural tone transfer and stable tuning

Electronics & Hardware — Heritage-3 Preamp and Modern-S Bridge

Electronics determine how much tonal flexibility the player has on stage and in the studio. The Marcus Super-J Revolution pickup set was revoiced for the New Gen line, and the Heritage-3 preamp adds a sweepable midrange plus push/pull active-passive switching — a combination that covers vintage passive thump and modern active precision in one instrument.

• Pickups: Marcus Super-J Revolution pickup set (SS configuration)
• Preamp: Marcus Heritage-3 with Middle Frequency Control
• Controls: Volume/Tone, Blender, Treble, Middle/Frequency, Bass (push/pull for Passive mode)
• Bridge: Marcus Miller Modern-S Bass Bridge — supports both string-through and top-load restringing
• Tuning Gear: Premium Lightweight Open Gear — reduces neck dive and improves balance
• Hardware Finish: Chrome
• Approximate Weight: ~4.0 kg (8 lbs 14 oz)

Who This Fretless Bass Is Built For

The Sire V7 Alder-4 New Gen FL Tobacco Sunburst is built for bassists who want the expressive, vocal quality of a fretless instrument paired with the tonal flexibility of a modern active preamp. It suits jazz, fusion, R&B, gospel, and soul players who rely on slides, vibrato, and the woody "mwah" of an un-fretted fingerboard. Intermediate and advanced players will appreciate the sweepable midrange for carving a precise slot in a live mix, while the push/pull passive mode delivers an old-school J-bass thump for traditional settings. The Sire V7 Alder-4 New Gen FL is the right choice for fretless-curious players who need an instrument that can cover both vintage passive tones and modern active EQ shaping without compromise.

The Sire x Marcus Miller Collaboration

Sire's partnership with Marcus Miller has produced a bass line designed to make professional-grade instruments accessible to a wider range of players. The V7 sits at the top of the Marcus Miller signature range, with the New Gen update refining the neck profile, electronics, and finish options based on direct input from Miller himself. The result is a fretless bass that carries the artist's tonal signature — warm, articulate, and unmistakably Marcus — in a package built for working musicians.
