A pick-up assembly for a stringed musical instrument includes first and second identical pick-ups in respective housings. The first pick-up is positioned toward strings of the instrument and the second pick-up is positioned toward inside of the instrument. The first and second pick-ups are attached back to back with a hard rubber sound suppressing material sandwiched between the back of the two housings. The sound suppressing material has the same size as the back of the housing. The second pick-up is grounded with a metal wire or is tuned to zero amplication.
