Sire Z Series Marcus Miller mahogany 4-string active bass guitar, Z3 4/SBS

The Sire Z3 Marcus Miller 4-String Active Bass Guitar in Skyburst Sparkle combines classic bass character with modern electronics and exceptional value. Designed for players who want punchy humbucker tone, deep low-end response, and versatile sound shaping, the Z3 delivers professional-level performance at an accessible price.

Built with Sire's newly designed Z-Bass body shape, the Z3 features a comfortable mahogany body with rounded contours inspired by iconic 1970s bass designs. The mahogany construction provides warmth, punch, and strong low-frequency response, making it suitable for a wide range of musical styles.

The hard maple neck features Sire's popular Edgeless™ fingerboard design, with rolled edges for a smoother and more comfortable playing experience. Its comfortable C-shaped profile and 34-inch scale length provide familiar feel and excellent playability for both beginners and experienced bassists.

At the heart of the Z3 is a Sire Standard MM pickup paired with the Marcus Heritage-3 active preamp. This active 3-band EQ system allows players to shape bass, middle, and treble frequencies with precision, offering everything from vintage-inspired warmth to modern punch and clarity. The result is a powerful, versatile bass tone suited to live performance, recording, and practice.

Finished in a striking Skyburst Sparkle, the Z3 stands out visually while delivering the sound and feel expected from a Marcus Miller-designed instrument.
