FJÆRLETT is an audio feedback instrument. You create feedback through reverb springs and shape that feedback signal with a graphic eq.

If you are interested, please sign up for the waitlist:

FJÆRLETT contains amplification and recovery circuits that can create audio feedback through the reverb springs.

The graphic equalizer is placed in the feedback loop and enables you to choose which frequencies that are fed back through the springs. The output signal is not affected by the eq.

Please note: Fjærlett does not come with a power supply. Fjærlett runs on 9v(negative polarity, 2.1mm plug) like most guitar pedals. If you own a guitar pedal power supply you can use that with Fjærlett. If you don't, please contact me and I'll help you find a suitable power supply.

Input mod

I offer a standerized modification which gives you the opportunity to use Fjærlett as a spring reverb effect. It features dry and wet controls and the possibility to shape the wet signal with the graphic equalizer. The mod adds an input jack, an effect mode switch and two pots for the dry and wet signal.
