String instrument and sound effect device

The invention provides a string instrument and a sound effect device. Even when the string instrument is played, an effect imparting part can be easily controlled. A stringed instrument (10) is provided with: an instrument body (11); a string attached to the musical instrument body (11); a pickup (13) that detects vibration of the string and outputs a string vibration signal corresponding to the vibration; a detection sensor (14) that is attached to the musical instrument body (11) and outputs a detection signal corresponding to a force applied to the musical instrument body (11); and a control unit (15) that is attached to the musical instrument main body (11) and outputs a control signal for controlling the operation of an effect imparting unit (16) that imparts an effect to the string vibration signal on the basis of the detection signal output from the detection sensor (14). 本发明提供一种弦乐器及音响效果装置，即使在弦乐器的演奏中也能够容易地控制效果赋予部。弦乐器(10)具有：乐器主体(11)；弦，其安装于乐器主体(11)；拾音器(13)，其对弦的振动进行检测，输出与该振动相对应的弦振动信号；检测传感器(14)，其安装于乐器主体(11
