Claims (1)

[Claims for Utility Model Registration] (1) At least one string is stretched on the body of the musical instrument, and this at least one string is provided with a string trigger switch that detects the start of vibration of the string. A fret condition sensing means is disposed on the swinger board to sense the fret operation position with respect to the string, and when the start of vibration of the string is detected by the string trigger switch, the fret condition sensing means sensed by the fret condition sensing means is disposed. In an electronic stringed instrument of the type that starts producing a musical tone on a string whose string vibration has started at a pitch corresponding to the operating position, the sounding string is stopped in response to the establishment of normal silencing conditions for each string. a normal mute control means for muting musical tones in a normal manner; one or more mute switches provided on the main body of the musical instrument; An electronic stringed instrument characterized by comprising: a mute mute control means that mutes the sound in a certain manner. (2) In the electronic stringed instrument according to claim 1 of the utility model registration claim, there is a plurality of strings, and the mute mute control means responds to the operation of the mute switch to mute the musical tones of all the strings that are being produced. An electronic stringed instrument characterized by muted sound. (3) In the electronic stringed instrument according to claim 1 of the utility model registration claim, the mute silencing control means comprises:
An electronic stringed instrument characterized in that musical tones are muted at a higher speed than when musical tones are muted by the normal mute control means. (4) Utility Model Registration The electronic stringed instrument according to claim 1, wherein the Myuto switch is comprised of a plurality of Myuto switches associated with a plurality of the strings.
