The Mag Machine


The “MAG” Machine® is the most accurate and reliable leak testing machine in the world, designed to reveal leaks in woodwind and brasswind instruments that cannot be found with other methods such as leak lights and feelers.

In addition, the MAG shows the precise degree of leakage in increments on the dial gauge.

The J.L. Smith MAG Machine® reveals even minute leaks (yes, these do affect performance!). The MAG is so effective it even shows the minor leakage of fingerprints on clarinet holes and French flute holes. Once the machine is calibrated, a perfect seal will read 0 on the meter. Therefore a “perfect job” will read 0 with light (first touch) pressure on the keys.
