Sire Guitars Er Gb5-4 Lh Bk Black

A Modern Single Cut Focused on Performance in the Marcus Miller Spirit

This GB5-4 LH fits into a modern approach to electric bass: a swamp ash body complemented by a poplar or burl top (depending on version), a neck-through construction, and full active electronics. The Single Cut silhouette promotes overall rigidity, resulting in a feeling of stability, sustain, and precision, especially appreciated on a fretless.

For Whom and Which Styles?

Designed for intermediate to advanced left-handed bassists, this 4-string fretless is tailored for nuanced playing: jazz, fusion, neo-soul, sophisticated pop, film music, and studio work. The 35" / 889 mm scale will appeal to those seeking a firmer low E string and better clarity in the low spectrum, while maintaining flexibility thanks to fine EQ control.

The Sound

Swamp ash provides a crisp attack, well-controlled lows, and airy highs, while the top (poplar or burl) refines the character by adding presence. The neck-through construction enhances sustain and note-to-note consistency, a major advantage for a fretless. The ebony fingerboard emphasizes definition and attack precision, ideal for the "mwah" and clean slides. The Marcus Pure-H Revolution pickup set combined with the Marcus Heritage-3 preamp (with mid frequency selection) allows switching from a round, deep sound to a more punchy and articulated tone, with very musical mid control to fit perfectly in the mix.

Recommended Compatible Accessories

To get the most out of the 35" / 889 mm scale, prioritize 4-string bass strings "extra long scale" suited for long scale instruments. Given the weight of 8.9 kg, a wide and padded strap is highly recommended to improve comfort during rehearsals and on stage.
