There is.

[0003]

By the way, in such a conventional electric guitar, the string vibration is converted into an electric signal by the pickup, and the electric signal is amplified by the amplifier and is sounded from the speaker. On the other hand, the string vibration is transmitted to the body through the bridge and is resonated in the body to produce a raw sound. The resonance vibration further vibrates the string through the bridge. Therefore, the vibration of the body portion also contributes to the tone color of the output musical sound. However, in such a conventional electric guitar, the emphasis is placed on firmly attaching the neck body to the body portion by integrally attaching the neck attachment portion to the body portion, and the acoustic aspect is not considered so much. As a result, the neck mounting portion does not vibrate sufficiently according to the string vibration transmitted to the neck mounting portion via the bridge, and there is a problem in that the string vibration reproduction efficiency and amplification efficiency are poor. An object of the present invention is to provide a stringed instrument that can improve the reproduction efficiency and amplification efficiency of string vibrations.
