Overwater Progress Series IV Custom 5 String Fretless

The Overwater Progress Series IV Custom 5-String Fretless represents the pinnacle of Overwater’s craftsmanship, delivering exceptional clarity, dynamic response, and expressive fretless tone. Evolving from the iconic Progress line introduced in the mid-1980s, the Series IV refines the design with improved ergonomics, tonal balance, and sound—all hand-built to world-class standards by Overwater’s master luthiers.

Built with a 35” 3-piece maple bolt-on neck, Indian Ebony fretboard with Maple fret lines, and African Walnut body with Maple top, the Progress Series IV provides remarkable sustain, stability, and effortless access across the entire fingerboard—essential for achieving the smooth, vocal quality fretless players rely on. Overwater’s flat-response 3-band Active EQ and internally shielded OWSB dual-coil pickups offer a wide tonal palette, from warm, singing mids to articulate, piano-like clarity. Its natural transparency allows the instrument’s wood character—and your technique—to shine through.

Designed for professional performance, this custom 5-string fretless offers exceptional physical balance, elegant aesthetics, and flawless playability with boutique hardware, high-precision construction, and handcrafted detailing, the Progress Series IV Fretless delivers a refined, expressive voice suited for jazz, fusion, ambient, modern worship, and any genre that demands nuance and articulation. A premium instrument built for players who expect nothing but the best.
