Ultrasonic precision and mechanical alignment.

01. Sediment Removal

02. Rotor Calibration

Decades of internal buildup dissolve without abrasive friction. The ultrasonic tank lifts debris from the deepest curves of the tubing, preserving the original integrity of the raw brass.

Valves are mechanically aligned for a silent, immediate response. We measure tolerances to the fraction of a millimeter, ensuring perfect acoustic seating before the instrument leaves the bench.

Calibrated by a professional ear.

Technical measurements only provide a baseline. As a working French hornist, the final evaluation is always acoustic. The instrument must speak instantly and resonate freely across all dynamic registers.

We understand the physical demands placed on a professional instrument. Every repair is play-tested in the workshop to guarantee it meets the absolute standards of the concert stage.
