Archer is a Milwaukee-based musical instrument brand offering acoustic guitars, electric guitars, bass guitars, and a range of stringed instruments including banjos, mandolins, and ukuleles. The brand operates as a house line of Cascio Interstate Music (through its ARU Music division), a family-owned Wisconsin music retailer founded in 1946. Archer instruments are designed and spec'd in Milwaukee and aimed at the beginner-to-intermediate price tier, with electric models drawing on familiar American body shapes — Stratocaster-style, Telecaster-style, Les Paul-style single cuts, semi-hollow thinlines, and P/J-style basses.

The Archer "Designed Series" represents the brand's step-up electrics, with models such as the TT-10 thinline (basswood body with flame maple top and P-90s), the SC-10DB single-cutaway, and the DC-10HC double-cutaway. On the acoustic side, Archer offers dreadnoughts, cutaway folk-style bodies, and classical nylon-strings. The line also includes artist signature instruments, notably the Josh Rouse Jazz Archtop and the K Sulton Signature Bass developed with session bassist Kasim Sulton (Todd Rundgren, Utopia).

Archer instruments are distributed primarily through Cascio's retail and e-commerce channels (Interstate Music) and other U.S. music retailers, positioning the brand as an affordable, value-focused house label rather than a boutique builder.

Archer has 3 products cataloged on Equipboard, including Power Amplifiers, Electric Basses, and Combo Guitar Amplifiers.
