ABSTRACT:
In an apparatus for modulation of the timbre of an electrical amplifier, in particular for guitars, a cylindric coil (2), which can be disposed downstream of an amplifier output, and a bar magnet (3) inside the cylindric coil (2), which can be deflected against restoring forces within a limited amplitude range out of its position of equilibrium, are provided for achieving a tonal effect corresponding to the direct connection of a loudspeaker.
