A stringed instrument microphone which is particularly optimized for many players of stringed instruments is disclosed. Uniformity and faithfulness of the electrical output is provided by employing a high-quality microphone mounted by a fraction to the sound box at a fixed position in which it does not interfere with the playing of the instrument. At the same time gone variation of this position is accommodated with a structure which maintains position rigorously. This is important because infinitesimally small variations in position will produce clearly audible distortions. In accordance with the invention it has been discovered that such variations may be caused, among other factors, by vibration of the sound box, a flexible or otherwise displaceable bracket structure and resonance in the bracket. The present invention optimizes the solution by providing a mounting configuration, multiple bracket material selections and arrangements, microphone characteristics and bracket configuration which cooperate to minimize distortions.
