Bragui is crafted to elevate musical hardware.
Innovation, precision, and performance, Bragui is crafted to elevate musical hardware.
Bragui is a family brand of high‑precision tuning machines founded by André, a mechanical engineer with deep expertise in advanced machining and precision systems developed for Swiss watchmaking, aeronautics, optical engineering, medical instruments, etc.
Rooted in the legacy of Portuguese guitar tuners— particularly ”Brandão & Guimarães” — Bragui was created to challenge industry conventions with a revolutionary approach and uncompromising standards.
More than a manufacturer, Bragui is a partner to musicians and luthiers, designing solutions that enhance and refine their instruments.
Launching with precision tuning machines for classical, acoustic, and electric guitars, Bragui blends engineering accuracy, mechanical reliability, and refined design.
Bragui tuners feature a unique, patented system that clearly sets them apart from the market.
Patented spindle‑to‑gear interface
The spindle and gear connect via a patented interface, ensuring perfect contact. This design compensates for wear over time, maintaining zero play throughout the tuner’s lifespan.
Interchangeable rollers for tonal shaping
Rollers are available in different materials—such as aluminum, stainless steel, brass and titanium versions forthcoming —allowing musicians and luthiers to subtly influence the instrument’s response and tone.
Premium plate materials
Available in aluminum and brass, with titanium versions forthcoming, offering different weight, resonance, and aesthetic options.
18:1 gear ratio
A finely tuned 18:1 ratio provides smooth, controlled, and accurate tuning adjustments.
Monoblock plate construction
The tuner plate is machined from a single solid piece, drastically reducing tolerance stack‑ups between the shaft holes and the plate—unlike conventional multi‑component designs. This results in superior alignment, stability, and precision.
Self‑lubricating
bronze gear
The gear is manufactured from a special bronze alloy with high hardness, ensuring excellent wear resistance. The material is naturally self‑lubricating, which reduces friction and wear while minimizing maintenance requirements.
Preloaded stainless‑steel spindle
The spindle (shaft) is made from stainless steel and incorporates a preloaded spring. Once installed and tensioned with strings, the system continuously presses the spindle against the gear, ensuring 100% tooth contact with zero backlash. This eliminates dead zones, prevents overshooting, and guarantees precise position holding.
Innovative V‑shape roller design
An exclusive V‑shaped roller option allows the string to follow two distinct paths, preventing string contact, improving string organization, and enabling faster and more stable tuning of nylon strings compared to traditional rollers.
