Get infinite sustain and controlled feedback...facing your audience, not your amp!

After years of only being available in Fernandes Sustainer models, the FSK401 is now for sale as a kit that you can install into your own personal guitar. The kit comes packaged with everything you need to have it installed into the electric guitar of your choice—(professional installation is highly recommended).

Now infinite sustain (the note keeps going…and going…) and total control of harmonic feedback (the kind you normally only get from certain angles on stage with the amp cranked up to 10) can be yours with the professional installation FSK401 or FSK101.

You too can have the tool that Steve Vai, Steve Lukather, and the Edge from U2 all coveted before they finally found sustain Valhalla. What are you waiting for?

How the Fernandes Sustainer works:
The patented Fernandes Sustainer is powered by a 9-volt alkaline battery, and works with the Driver in the neck position, the Bridge pickup, and the Sustainer circuitry to give you infinite sustain. The driver sends magnetic pulses to the strings, which makes them vibrate. (The driver also functions as a great sounding neck pickup when the Fernandes Sustainer is switched off.)

Standard Mode: In the Standard mode, the Fernandes Sustainer will hold any note you play.

Harmonic Mode: In the Harmonic mode the Fernandes Sustainer creates string vibration similar to that when you're getting feedback at extreme volume, generating the 5th harmonic of the note being played.

Mix Mode (FSK-401 only): The Mix mode is a blend of Standard and Harmonic sustain.
