Small Stabilizer, Big Sound!

The tone stabilizer from Martin Seibold is screwed in as a connecting intermediate piece in the valve casing of the instrument. The sound becomes fuller and purer thanks to the Tone Stability Enhancer (TSE). The tones respond more easily and lock in better, making the player perform more confidently and securely. The tone stabilizer is hardly noticeable in weight and can be mounted almost invisibly on the instrument due to its compact size.

Easy Installation

For installation, unscrew the knurled screw from the TSE. Place the threaded part from behind onto the valve casing as shown in the sketch (see image 2) and hand-tighten both parts together using the knurled screw so that the TSE rests against both valve casings.

About the Manufacturer

The idea for the Tone Stability Enhancer comes from Martin Seibold, who has made a name for himself as a supplier of small parts for instrument makers. His company is based in Baiernrain, a district of the Upper Bavarian municipality of Dietramszell. Martin Seibold is especially known as the inventor of the established Minibal ball joint, which he introduced in the mid-1990s.
