Sire P7 Alder-4 New Gen Tobacco Sunburst 4-string Bassguitar

Precision Bass Tone with Modern PJ Flexibility

The Sire P7 Alder-4 New Gen Tobacco Sunburst is a four-string Precision Bass-style instrument that blends the punch of a P-style split-coil with the clarity of a J-style single-coil in one flexible platform. A North American alder body in the classic Sire P shape provides the balanced weight and resonant character that working bassists rely on, while the roasted hard maple C-shape neck and ebony fingerboard deliver a smooth, broken-in feel from the first session. Players who want one instrument that covers R&B grooves, jazz lines, pop stylings, and aggressive rock rhythms will find this bass ready for the task. The Sire P7 Alder-4 New Gen Tobacco Sunburst is engineered for bassists who need vintage warmth and modern articulation in the same instrument.

What Sets the New Gen Apart

What makes this model stand out in the PJ category is the combination of Edgeless rolled fretboard edges and 2.4 mm medium stainless steel frets, which together create a playing surface that feels fast and stays accurate over years of heavy use. The Marcus Super-PJ Revolution pickup set pairs a split-coil neck pickup with a single-coil bridge pickup, then routes the signal through the Marcus Heritage-3 preamp with a dedicated middle-frequency control and an active/passive mini toggle for instant tonal switching. A real bone nut, the Marcus Miller Modern-S bridge, and lightweight open-gear tuners complete a hardware package that feels far more refined than its price tier suggests.

Body, Neck, and Playability

The body and neck combination is the foundation of the P7 New Gen's playing feel. North American alder is a tonewood prized for its balanced response, prominent upper-mids, and lightweight resonance, making long sets and studio marathons noticeably easier on the shoulders. The roasted hard maple neck adds stability against humidity changes and gives the bass a smooth, vintage-style feel under the thumb.

• Body Material: North American Alder — balanced weight with clear upper-mid presence
• Neck Material: Roasted Hard Maple — added stability and a smooth, broken-in feel
• Fingerboard: Ebony with Edgeless rolled edges — fast navigation and reduced hand fatigue
• Scale Length: 864 mm (34") — standard long-scale tension for full-range response
• Fingerboard Radius: 241 mm (9.5") — a versatile curve for both chord work and fast lines

Pickups and Electronics

The pickup and preamp system is where this model earns its reputation for tonal flexibility. The Marcus Super-PJ Revolution set covers the assertive thump of a P-style bass and the throaty growl of a J-style bass, while the Heritage-3 preamp adds a three-band EQ with a sweepable midrange for precise tone shaping. A pickup blender keeps both pickups in dialogue, and the active/passive mini toggle lets players drop into a more natural, organic response without changing EQ settings.

• Pickup Configuration: PJ (split-coil neck + single-coil bridge) — covers both P-style punch and J-style clarity
• Preamp: Marcus Heritage-3 with Middle Frequency Control — three-band EQ plus sweepable midrange
• Controls: Volume/Tone (Dual Pot), Pickup Blender, Treble, Middle/Middle Frequency (Dual Pot), Bass, Active/Passive Mini Toggle

Hardware and Construction

Hardware choices reinforce the gig-ready character of the instrument. The Marcus Miller Modern-S bridge supports solid tuning stability and clear note definition, while the premium lightweight open-gear tuners reduce overall weight and improve balance on a strap. A four-bolt steel plate neck joint, chrome hardware finish, and tortoise pickguard complete a setup that looks as professional as it plays.

• Bridge: Marcus Miller Modern-S Bass Bridge — solid sustain and string stability
• Tuning Gear: Premium Light Weight Open Gear — reduced weight and smooth action
• String Spacing: 20 mm — comfortable reach for both fingerstyle and pick playing
• Nut: Bone, 42 mm width — solid tone transfer and tuning stability
• Construction: Bolt-on, four-bolt steel plate — classic P-style neck attachment

Who This Bass Is For

The Sire P7 Alder-4 New Gen Tobacco Sunburst is the right choice for working bassists and serious students who need one instrument that covers studio sessions, live gigs, and rehearsal work without compromise. Players coming from a passive P-style setup will appreciate the added clarity of the J-style bridge pickup and the option to switch into passive mode for a more traditional response. Intermediate and advanced players exploring funk, jazz, gospel, pop, and rock will find the Heritage-3 preamp's sweepable midrange especially useful for locking into a mix. The lightweight alder body and rolled fretboard edges also make it a strong fit for bassists who play long sets and want a neck that feels comfortable from the first note to the last.

The Sire and Marcus Miller Story

Sire's Marcus Miller signature line is developed in collaboration with the legendary bassist Marcus Miller, whose playing specifications and design feedback shape every update to the series. The New Gen revision reflects input gathered from the V7, V7 Vintage, and P7 2nd Gen ranges, refining the neck profile, hardware, and pickup voicing for the modern player. This collaboration has positioned the Marcus Miller P-series as a benchmark for professional-feeling instruments at an accessible price point.
