JEK FX is a boutique guitar and bass effects pedal maker based in Saint Petersburg, Russia. The company builds a small, focused lineup of hand-assembled analog stompboxes aimed at both stage and studio use, with an emphasis on component quality and transparent signal paths.

The catalog includes the Squeezer and Squeezer 2 VCA compressors (built around THAT Corp. VCA chips and offering controls for gain, mix, threshold, ratio, and a switchable manual attack/release mode), the Airblaster overdrive, the Eclipse, the Splinter effects-loop/controller pedal, and the Enigma, a two-channel bass preamp with overdrive and saturation voicings intended for direct recording or front-of-amp use.

Distribution is handled directly from the workshop, with shipping across Russia and the EAEU region. The brand has developed a following among Russian session players and touring musicians across pop, metal, and alternative acts.

JEKFX has 8 products cataloged on Equipboard, including Compressor Effects Pedals, Overdrive Effects Pedals, and Bass Effects Pedals.
