Abstract
An electrically amplified percussive instrument has at least one tone bar having a bottom side and fundamental nodes each of the fundamental nodes defined by a channel. A permanent magnet on the bottom side of the tone bar is proximal to one of the fundamental nodes and not aligned with a location of maximum tone bar vibration. A pickup coil positioned underneath the tone bar is aligned with the first permanent magnet and in electrical communication with an amplifier.
