Sire Marcus Miller M7 Swamp Ash-4 Nt En

A "modern bass" designed for the stage in the spirit of the M series

The M7 Swamp Ash-4 NT EN embraces a decidedly contemporary approach: a "New modern bass" format designed for performance, modern ergonomics, and electronics capable of covering a wide sonic spectrum. The idea is simple: maintain a natural and lively passive base, then switch to active to precisely shape the sound according to the context (band, studio, stage). The Natural finish highlights the swamp ash grain and enhances the model's "stage instrument" look.

For which bassists and styles?

This bass is primarily aimed at intermediate to advanced bassists seeking a versatile, precise, and responsive 4-string with real adjustment possibilities. It is particularly comfortable in pop, funk, gospel, modern rock, fusion, and urban music: the long scale provides solid low-end support, and the 3-band EQ with parametric mids helps instantly find the right place in the mix.

Sound characteristics

Swamp ash is known for its quick response and clear articulation: firm lows, strong projection, and an attack that "speaks" easily, especially when playing fingerstyle or with a pick. The maple neck enhances the sense of snap and precision, while the ebony fingerboard adds definition and very clean articulation, ideal for slap and fast passages. The Marcus Pure-H Revolution pickups deliver a balanced foundation, and the Marcus Heritage-3 preamp allows for a range from organic tones to a more modern signature: beefier lows, more present highs, and especially adjustable mids (level and frequency) to shape the character without losing clarity. The active/passive mini toggle is a real plus for changing sonic aesthetics with a single gesture.

Recommended compatible accessories

With its 34" / 864 mm scale length, this bass accepts 4-string long scale bass strings. The original gauge 45-105 offers an excellent balance between comfort, attack, and tuning stability, especially if you alternate fingerstyle, slap, and pick playing.
