Story of an invention

The 'wolf tone', is a parasitic vibration on a string, it is the result of a conflict of sound frequencies. To avoid this, musicians use Wolf tone eliminator that adds weight to the string, which removes conflicting sound frequencies but causes an undesirable effect of mute.

Not satisfied with this solution, André Theunis, Master Luthier and acoustic enthusiast, undertook research to find a non-invasive solution. After several years of studies and tests, he ended up creating the "Wolf Tuner" to tame the wolf rather than smother it.
