A method of assembling an anti-wolf resonator assembly for use with a string instrument is provided. The method includes positioning a first portion of the resonator assembly against a first side of a surface of the instrument, and magnetically coupling a second portion of the resonator assembly to a second side of the instrument surface that is opposite the first side of the surface. The surface is positioned between the first and second portions of the resonator assembly. The resonator assembly is configured to dampen at least one of a musical note and a vibration produced by the string instrument.
