摘要：
Small portable device for pre-stressing and holding replacement strings for a musical instrument, comprises a beam part along which the strings extend and to one end of which they are fastened. The other end of the beam part has manually operable string attachment and draft keys, for tensioning the strings the desired amount. The beam part has frets spaced with relation to the diapason of the musical instrument, to aid in tuning the replacement strings to the necessary pitch.
