Fernandes Guitars


Since the 1960’s, electric guitarists have been left scratching their heads, seeking an effective way to control sustain and feedback. Behold!
The FERNANDES SUSTAINERTM… puts that power right at your fingertips with just the flick of a switch. Bust out texture and tonal coloring ala Hendrix at any level of volume with our patented technology. Use the Sustainer on single notes, use it on chords, adjust it to give swells or for a gradual decay to the ‘sustain’.

What is the Fernandes Sustainer?

The FERNANDES SUSTAINERTM is a uniquely designed electronic system that enables the controlled sustain of any single or group of notes within the guitar’s sound range. At your discretion, strings will emit sound at a consistent intensity until stopped, regardless of output and/or location, even if the guitar is not connected to an amplifier!

How does it work?

The patented FERNANDES SUSTAINERTM system generates a magnetic field causing the strings of the guitar to vibrate.
Poweredby a 9-Volt battery, the interaction of the bridge humbucking pickup(B), the Sustainer Circuit Board(C) and the neck Sustainer Driver pickup(A), projects magnetic pulses that continuously vibrate the strings of the guitar, the same way an amplifier would at extreme volumes, yet totally controlled! The result is infinite sustain and/or feedback using sparkly clean or loud distorted settings without the need for excessive volume or extra outboard gear!



01Harmonic Mode:
Within seconds, the pitch of the ringing note(s) will rise to the 5th natural harmonic.

02Natural Mode:
The note(s) will continue to ring its natural fundamental tone as long as the string(s) are free to vibrate and the Sustainer System is on.

03Mix Mode:
Available on select models including our FSK-401 Sustainer Kit, the Mix mode blends the Natural and Harmonic Mode to harmonize indefinitely every ringing note creating a harmonized feedback effect.

What can the sustainer do for you?

Enhance your creativity with the Fernandes SustainerTM. Use with any combination of gear in your arsenal of effects, amp modelers and home recording equipment. Discover new sounds as you explore the world of controlled sustain and feedback.
