Claims

[Scope of claim for utility model registration] String operation detection means disposed on the main body of the musical instrument;
It has at least a musical sound generating means and a pitch specifying operation means disposed on a finger board extending from the main body of the musical instrument, and the string operation is detected by the string operation detection means. Therefore, in an electronic stringed instrument in which the musical sound generating means produces a musical tone of a pitch specified by the pitch specifying operation means, an after-sound device, which is disposed on the side of the finger board, is provided to produce a musical tone with a pitch specified by the pitch specifying operation means. an after-control data input means for inputting after-control data for imparting an effect; and an after-control data input means for imparting an after-effect to a musical tone being sounded based on the after-control data inputted by the after-control data input means. An electronic stringed instrument characterized by comprising: an effect imparting control means;
