String instrument effector device

The utility model relates to the string instrument equipment technical field, and especially relates to a string instrument effector device comprising an effector body arranged in/outside a string instrument body; the effector comprises a pick up module; one end of the pick up module is electrically linked with one end of an amplification module; the other end of the amplification module is electrically linked with one end of a first amplification filter module; the other end of the first amplification filter module is simultaneously and electrically linked with one ends of an original sound module and a modified tone module; the other end of the modified tone module is electrically linked with a second amplification filter module; the other ends of the original sound module and the second amplification filter module are respectively and electrically linked with an electronic switch controlled module; a reverb and a modified tone chip are combined to control through an electronic switch, thus forming string instrument effector tone quality and effect; a touch switch mode is used to fast control and switch effects; the string instrument effector device is simple in structure, convenient in switching operation, thus greatly improving tone quality and effect.
