Sire P7 Alder-4 New Gen Antique White 4-string Bassguitar

Sire P7 Alder-4 New Gen — Marcus Miller's Hybrid PJ Bass Refined

The Sire P7 Alder-4 New Gen is a 4-string electric bass designed with legendary session bassist Marcus Miller, blending the punchy character of a Precision with the tonal flexibility of a Jazz Bass. Built on a North American Alder body in the classic Sire P shape, this New Gen edition introduces Edgeless rolled fretboard edges, stainless steel frets, and a redesigned Modern-S bridge. At its core sits the Marcus Super-PJ Revolution pickup set paired with the Heritage-3 active preamp, delivering a remarkably wide tonal palette from a single instrument. The Sire P7 Alder-4 New Gen Antique White is the right choice for working bassists who want P-style authority with J-style articulation.

What Sets the New Gen P7 Apart

Two upgrades set the New Gen P7 apart. The Edgeless rolled fretboard edges — normally reserved for custom-shop instruments — give the neck a smooth, worn-in feel that reduces hand fatigue during long sessions. The Heritage-3 preamp now includes a dedicated Middle Frequency control on a dual-pot layout, letting bassists sweep the midrange point to cut or boost any frequency.

Body Construction — North American Alder Tonewood

Alder has long been the tonewood of choice for classic P-style basses, prized for its balanced response and pronounced midrange. The Sire P7 New Gen uses North American Alder in the Sire P body shape, finished in Antique White with a tortoise pickguard and ivory single-ply binding.

• Body Material: North American Alder — balanced tonal response with strong midrange presence
• Body Shape: Sire P Type — classic Precision-style silhouette
• Construction: Bolt-on, Four Bolt Steel Plate neck joint — solid transfer of string energy to the body

Neck and Fingerboard — Roasted Maple with Edgeless Comfort

The Roasted Hard Maple neck offers enhanced stability and a vintage-tinted aesthetic, while the Ebony fingerboard delivers bright attack and crisp note definition. Edgeless rolled edges smooth the transition between fretboard and neck, comparable to a well-broken-in vintage instrument.

• Scale Length: 864 mm (34") — standard long-scale P-Bass tension and response
• Neck Material: Roasted Hard Maple — improved stability and resonance
• Fingerboard: Ebony with Edgeless rolled edges — bright attack with smooth hand-feel
• Fingerboard Radius: 241 mm (9.5") — comfortable for chord work and lead lines
• Frets: 2.4 mm medium stainless steel — long-lasting durability and smooth bending
• Nut: Bone, 42 mm width — natural lubrication and tuning stability

Electronics and Hardware — Super-PJ Pickups and Heritage-3 Preamp

The Marcus Super-PJ Revolution pickup set pairs a split-coil P-style pickup in the neck with a J-style single-coil at the bridge, delivering both the fat thump of a Precision and the articulate growl of a Jazz Bass. The Heritage-3 active preamp adds an 18V-powered 3-band EQ with sweepable midrange, plus a mini-toggle for instant passive mode.

• Pickup Configuration: PJ (Super-PJ Revolution set) — P-style thump plus J-style clarity
• Preamp: Marcus Heritage-3 with Middle Frequency Control — 18V active 3-band EQ with sweepable mid
• Controls: Volume/Tone (Dual Pot), Pickup Blender, Treble, Middle/Middle Frequency (Dual Pot), Bass, Active/Passive Mini-Toggle
• Bridge: Marcus Miller Modern-S Bass Bridge — enhanced sustain and string stability
• String Spacing: 20 mm — comfortable for pick and fingerstyle players

Who Should Play the Sire P7 Alder-4 New Gen

The P7 is the right choice for working bassists, session players, and serious hobbyists who want a flexible 4-string with both vintage character and modern tonal flexibility. Players coming from a traditional P-Bass will appreciate the familiar feel and authoritative low-end thump, while those seeking more sonic range will find the J-bridge pickup and Heritage-3 preamp open up a wider palette. It suits genres from Motown and R&B to jazz, fusion, pop, and modern rock. The active/passive mini-toggle also makes it ideal for gigging bassists who want a natural passive tone without sacrificing EQ settings between songs.

The Sire and Marcus Miller Collaboration

Sire has built its reputation by partnering with legendary bassists to design instruments that deliver professional-level features at accessible prices. The Marcus Miller signature line represents one of the brand's most successful collaborations, with the Grammy-winning bassist contributing directly to pickup voicing, preamp design, and playability specifications. The P7 sits as the flagship P-style model, reflecting Miller's preference for instruments that combine traditional P-Bass character with modern tonal flexibility.
