Flux Effects is a boutique guitar pedal manufacturer based in Christchurch, New Zealand. The company was started by Michael Weavers in 2003, though its first commercial product — the Liquid Tremolo — didn't arrive until late 2012. Weavers brings a background in electronics design, and the pedals are built in small batches, individually tested and laser-engraved with serial numbers.

The catalog centers on atmospheric, texture-driven effects rather than traditional drive or distortion. The Liquid Ambience pairs a hall reverb with a polyphonic octave generator and a 'bend' control that glides the reverb tail up or down to a preset octave. The Liquid Tremolo is a stereo analog tremolo with tap-tempo, MIDI, and a selection of wave contours, and the Slipstream Delay rounds out the range with modulated delay textures. The pedals are aimed at ambient, post-rock, and experimental players looking for lush, movement-oriented sounds.

Flux Effects distributes through boutique retailers and Reverb, and a portion of proceeds supports charity: water.

Flux has 20 products cataloged on Equipboard, including FX Bundle Plugins, EQ Plugins, and Stereo Width Plugins. Their gear is featured by 12 artists, with the strongest followings in Electronic, Stage & Screen, and Rock. Notable users include Boris Brejcha, Kaskade, and 3RI5.
