The Sustainer System, now available for any solidbody guitar.

The FSK-401 Sustainer by Fernandes is an electromagnetic system powered by a 9V battery. It magnetically vibrates the guitar strings once you have set them in motion, to give you nearly endless sustain and, in a second mode, to give you harmonic feedback at any volume level. Installation of the Sustainer Kit may require routing.


  • In standard mode will continuously vibrate the note
  • In harmonic mode will create 5th harmonic feedback at any volume level
