Sire Marcus Miller M5 Swamp Ash-4 Left-Handed Transparent Blue En

An M5 Designed as a Modern "Enhanced" Bass in the Spirit of Marcus Miller

The Sire M5 embraces a decidedly contemporary approach: a bass with a modern look, built to withstand energetic playing and varied styles. The idea is simple: start with a contemporary base (modern bass style body, 24 frets) and add carefully chosen materials and comprehensive electronics to achieve an expressive, precise bass ready for both stage and studio.

With its black hardware and finishes labeled "NT, TBL," the M5 displays a strong visual character, consistent with its modern feel and "performance" philosophy.

For Which Bassists and Styles Is the Sire M5 Swamp Ash-4 Made?

The M5 Swamp Ash-4 targets the bassist who wants one bass that can do it all: current pop, funk, R&B, modern rock, metal, gospel, fusion... Its extensive control arsenal allows you to adjust attack, bass level, mid presence, and brightness instantly, ideal when switching between songs without changing instruments.

Thanks to its playing comfort (ebony fingerboard, rolled edges, 24 frets), it suits both an intermediate player seeking a "grow-with-you" bass and an advanced musician expecting precise control and a wide tonal palette. Slap, fingerstyle, pick playing, and fast back-and-forth lines in the upper register feel at ease on this platform designed for speed and clarity.

A Modern, Powerful, and Sculptable Sound Thanks to the Pure-H Revolution Pickups and Heritage-3 Preamp

The Marcus Pure-H Revolution pickups + Heritage-3 preamp duo gives the M5 a sonic identity emphasizing power, definition, and mix placement capability. You can stay with a direct, dynamic sound in passive mode or activate the circuit to boost lows, open up highs, and especially work the most sensitive area for presence: the mids, thanks to the center frequency control.

The control section is designed for the stage: volume/tone on a dual potentiometer, pickup blend, 3-band EQ (treble, mids, bass) with dual potentiometer mid-frequency adjustment, and dedicated mini-toggle switches. The series / split / parallel switching offers very useful tonal variations: a denser, "thicker" register, a more open and articulated texture, or a more hi-fi balance depending on your attack.

On the craftsmanship side, swamp ash is valued for its quick response and balance, while the 5-piece maple/mahogany neck promotes stability. The Heavy Mass bridge contributes to a well "placed" note feel, with a clear attack and convincing sustain, particularly appreciated in percussive playing and lines that need to remain clear.
