Guardelli Sound Modulator

The new generation of magnetic cello wolf eliminator considered by instrument players and luthiers as the most effective device for the elimination of wolf notes while not having any negative influence on the instrument’s tonal qualities. Guardelli Sound Modulator was developed during long-lasting sound laboratory research, resulting in an ideal interaction between the magnetic field,strength, the weight and the length of the device,in order to fully eliminate the wolf notes while preserving the tonal potential of the instrument and simultaneously eradicating negative aspects present in other wolf eliminators with the transfer of unwanted buzzing vibrations on to the device itself while playing more dynamically being the most important.

Guardelli Sound Modulator consists of a high-power neodymium outer magnet embedded in a wooden shell , a metal installation rod and an internal tube with magnetically levitating piston which inserts inside the instrument through the left/ bass f-hole and gets magnetically connected with the outer magnet for smooth manipulation across the top plate surface.
