Precision Tools, Traditional Craftsmanship
The Rueil-Malmaison workshop is equipped with high-accuracy tools and specialized fixtures designed in-house to ensure perfect repeatability and fine tolerances.
Each repair follows a rigorous workflow — from initial diagnostic using digital gauges and feeler sensors to the final setup tested by hand.
Our background in precision instrument making and modern lutherie allows us to combine traditional hand techniques (nut carving, fretwork, finishing) with advanced mechanical processes like CNC-cut jigs, calibrated sanding, and electronic calibration tools.
The result: consistent playability, precise tuning stability, and long-term reliability — whether we’re setting up a Stratocaster, refinishing a Les Paul, or restoring a vintage Jazz Bass.
