Sire V7 Vintage Swamp Ash 5 New Gen 5-String Bass Guitar in Natural

The Sire V7 Vintage Swamp Ash-5 New Gen in Natural is a 5-string jazz-style bass designed to capture the classic 70s Marcus Miller sound, with modern playability and flexible electronics. A swamp ash body, maple neck and fingerboard, and Marcus Vintage-J Revolution pickups feed into the Marcus Heritage-3 preamp, giving you everything from warm, plush vintage tones to punchy, articulate modern sounds at the flick of a switch.

Seven years on from the 2nd Gen, the New Gen V7 Vintage refines Sire’s flagship formula with a more comfortable neck, upgraded controls and a more expressive pickup and preamp pairing. Whether you are chasing tight, percussive slap, smooth R&B lines or detailed fingerstyle, this bass is built to deliver that unmistakable Marcus-inspired character while staying comfortable through the longest sets.

Vintage-Inspired Tone with Modern Flexibility

At the heart of the V7 Vintage New Gen is a pair of Marcus Vintage-J Revolution single-coils, voiced to recreate the classic 70s jazz bass sound. Using Alnico magnets and vintage-correct construction, they produce a warm, rounded low end, a musical midrange and a sweet, singing top. Paired with the Marcus Heritage-3 preamp and its powerful yet musical EQ, you can dial in everything from fat, old-school thump to bright, cutting slap tones, all while retaining clarity and nuance.

New Gen Neck with Edgeless Comfort

The New Gen neck is built for serious players who value comfort and control. A familiar C-shape maple neck and 34-inch scale feel instantly at home, while Sire’s Edgeless rolled fingerboard edges create a remarkably smooth playing surface. Combined with the 7.25-inch radius and black block inlays, you get a neck that feels fast and inviting for both modern and vintage styles, encouraging clean runs and accurate intonation right up the neck.

Swamp Ash Body and Classic Jazz Styling

The swamp ash body delivers the lively, resonant response that has made this tonewood a favourite for funk, fusion and beyond. It offers a tight, defined low end with a clear, airy top that lets your playing dynamics shine through. The New Marcus Miller Jazz Type body shape keeps things familiar and well-balanced on a strap or seated, while the Natural finish lets the grain of the ash speak for itself for a timeless, stage-ready look.

Active or Passive at the Flick of a Switch

The V7 Vintage New Gen gives you instant access to both active and passive operation via a mini toggle switch. In passive mode you get straightforward, classic jazz bass response with Volume/Tone and Pickup Blender controls. Switch to active and the Marcus Heritage-3 preamp comes alive, adding powerful Bass, Treble and sweepable Mid controls for sculpting your sound to the room, the band and the track. If the battery runs low mid-gig, simply flip back to passive and keep playing with confidence.

• Swamp Ash Body for Classic Snap and Clarity - The swamp ash body provides a bright, articulate response with tight lows and a lively midrange, ideal for funk, fusion and any style that demands definition and punch. Its natural resonance helps every note speak clearly, whether you are playing fingerstyle, slap or with a pick.
• Marcus Vintage-J Revolution Pickups - Voiced to capture the iconic 70s jazz bass character, these Alnico single-coils deliver a warm, plush tone with plenty of presence. They respond beautifully to your touch, giving you smooth, singing lines at low gain and aggressive bite when you dig in.
• Marcus Heritage-3 Active/Passive Preamp - The Heritage-3 preamp offers a powerful yet musical EQ section with Bass, Treble and a sweepable Mid control, so you can fine-tune your sound for any mix. The dedicated mini toggle lets you switch between active and passive modes instantly, giving you both vintage simplicity and modern versatility in one instrument.
• New Gen Neck with Edgeless Fingerboard - A hard maple neck with a C-shape profile and Edgeless rolled fingerboard edges provides exceptional comfort, reducing hand fatigue over long sessions. The 7.25-inch radius, black block inlays and natural bone nut combine for a smooth, precise playing feel that suits everything from fast runs to laid-back grooves.
