What is a wolf tone?

The wolf is a sustaining sympathetic vibration overtone and is produced when the original note matches the natural resonant frequency of the body of the musical instrument.

 

What are the current solutions?

The conventional wolf tone eliminators, usually remedied this by the addition of weight on the string, which stifles it with muting effects that affect the sound quality.

 

Why is the wolf-tuner better than

the other wolf tone eliminators?

The Theunis Wolf-Tuner is 3 times lighter than a conventional Wolf tone eliminator.

Its design and composition are based on its resonance

rather than its weight.

It avoids the muting effect while tuning the conflicting frequencies and it enriches the harmonics.

 

How is the Theunis Wolf-Tuner made?

Like a piece of jewelry, every single Wolf-Tuner is handcrafted.

The metal is rolled and hammered in order to harden it and thus develops its sound properties.

The Story of an Invention

G spot image Theut face.jpg.gif

Since 50 years, André Theunis, is a Master-Luthier and an acoustic enthusiast.

Passionate by the improvement of the sound of his instruments, Andre devoted his entire career to find a non-invasive solution to the wolf.

 

After countless studies and tests, his research led Andre Theunis

to discover the exact proprieties of the Wolf-Tuner

that tunes the wolf rather than smother it.

 

In order to make his fellow Luthiers discover it,

he presented his invention at the Congress of the International Association of Violin and Bow Makers, in Prague in 2011.

After a demonstration, it is with a standing ovation

that the Wolf Tuner was welcomed.

To go deeper into the understanding of its effectiveness,

the Wolf-Tuner has been submitted to researchers at

the universities of Nice (France) and Potsdam (Germany).

 

They successfully confirmed its positive effect

on the conflicting frequencies compares to others

conventional wolf tone eliminators.


For a long time, the Wolf-Tuner was sold exclusively to the professional musicians who work with him.

Because his invention deserves to be widely known, the wolf tuner is now available to everyone through this website.
