The 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 wolf notes while preserving the tonal potential of the instrument and simultaneously eradicating negative aspects present in other wolf eliminators.
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.
The wolf eliminator can be used with all sizes of cello, and double bass.
Fitting instructions included. Can be installed and adjusted at home, no need for additional tools or luthier fitting.
