Abstract
An electric percussion instrument having at least one drum head is provided with a mute assembly arranged near the drum head and at least one mechanical-electric convertor containing a vibration responsive pickup element is incorporated into the mute assembly. Direct collection of the drum head vibrations via the mute assembly successfully precludes undesirable mixing of external vibratory noises which are transmitted to the drum frame.
