Custom Five String Haynes Jazz Bass

Built for Players Who Demand More

The Custom Five String Haynes Jazz Bass is a hand-crafted instrument born from decades of luthiery expertise and a deep respect for tone. Designed and built in the UK, this is not a production-line bass — it is a considered, purposeful instrument made for the player who knows exactly what they want.

The Feel of Five Strings Done Right

The extended low B string opens up a world of harmonic depth and tonal range without compromising the classic Jazz Bass playability you already know. The neck profile is shaped for comfort across all five strings, so whether you're locking in a groove or exploring the upper register, the bass responds with precision and ease.

Craftsmanship You Can Hear

• Hand-wound Haynes pickups — wound in-house for balanced output, clarity, and vintage-inspired warmth across all five strings
• Premium tonewoods — carefully selected for resonance, sustain, and aesthetic beauty
• CNC-precision body and neck — machined to exacting tolerances, then hand-finished for a truly bespoke feel
• Classic Jazz Bass double-cutaway body — ergonomic, balanced, and instantly familiar
• Five-string configuration — full low B to high C range for extended musical expression

A Bass That Tells a Story

Imagine sitting in a rehearsal room, the low B string resonating through the floor, your bandmates nodding as the tone fills the space. That's what a Haynes Jazz Bass delivers — not just an instrument, but a presence. Every detail, from the hand-wound pickups to the final setup, is done with intention.
