A pick-up cartridge for a gramophone record comprises a cartridge shell in which is mounted a stylus assembly including a short, rigid stylus arm and a resilient wire which is much shorter in length than the arm and is attached to the rear end of the arm in alignment with a rear straight part of the arm. Transducer means responsive to movement of the arm are located ahead of the resilient wire and the wire is attached at its rear end to a mounting member supported in the cartridge shell so that the stylus assembly extends forwardly and downwardly away from the cartridge shell. A stylus tip attached to the stylus arm adjacent the forward end thereof is located in the vicinity of the axis of the straight part of the arm.
