Sire is a guitar and bass manufacturer known for producing professional-quality instruments at accessible price points. The brand's origin traces to a group of Korean musicians who wanted to build the gear they themselves wanted to play, and Sire broke out in the mid-2010s with the release of the Marcus Miller V7 signature bass — a Jazz-style instrument co-developed with Grammy-winning bassist Marcus Miller that aimed to offer boutique-level playability without a boutique price.

The Marcus Miller line has since expanded to include a range of J-style (V-series), P-style (P-series), and modern humbucker-equipped (M-series) basses, while the guitar side of the catalog is anchored by the Larry Carlton signature models — semi-hollow and solid-body electrics co-designed with the fusion and session guitarist. Both artists collaborated on Sire's signature pickup designs, and the instruments are typically specced with features more commonly found on higher-end guitars: premium tonewoods such as swamp ash, alder, and roasted maple, rolled fretboard edges, stainless steel frets, and active/passive preamps on the bass side.

Sire has built a reputation, particularly in the bass community, as one of the go-to brands for players looking for a gigging-grade instrument without a flagship price tag. The company is especially visible on forums like TalkBass and among educators and YouTube demo channels, and its basses are widely stocked by retailers including Sweetwater, Guitar Center, and Chicago Music Exchange.

Sire USA has 174 products cataloged on Equipboard, including Electric Basses, Solid Body Electric Guitars, and Fretless Basses. Their gear is featured by 20 artists, with the strongest followings in Rock, Jazz, and Funk / Soul. Notable users include Larry Carlton, Marcus Miller, and Davie504. Most Sire USA products fall in the mid-tier range — professional-grade without flagship pricing.
