JST Demon Fuzz is a beautifully dirty, texture-rich distortion plugin for tone design.

Inspired by the designs of fuzz pedals, JST Demon Fuzz features three distinct tones that mix the smooth, harmonic sustain of a fuzz effect with the grit and depth of distortion, creating the ideal solution for adding bite or saturation to your mix.

JST Demon Fuzz features a three-way toggle that offers Normal, Bass Boost, and Dry options. Additional Volume, Tone, and Sustain controls provide even more tweaking. Dime the output to hit your signal harder; dial back the Tone to muddy the distortion, or turn it up to add more top end; max the Sustain to more resonance, or turn it down to clean it up just slightly.



In addition to the base features on the pedal, the “Advanced” tab opens up all the customization you could ask for:

  • Input & Output Control
  • Noise Gate
  • Mix knob to blend the dry and processed signals
  • High Pass & Low Pass filter slider
  • Polarity options
  • Compression
  • Character to control the sound of the distortion
  • Mids to control how much the mids are cut or boosted
  • Tone button to enable or disable the tone circuit
  • “Wicker” to open up the frequency bandwidth for a clear top end
  • “Alt Circuit” to enable or disable an alternative fuzz circuit

Plug and play with your favorite Toneforge or Bassforge Amp Sim, load up presets, or tweak to perfection to create the most sinister sound you can find - the choice is yours! JST Demon Fuzz is perfect for:

  • Guitars
  • Bass
  • Synths
  • Sound Design
  • Effects
  • Drums

Awesome sound

I love this plugin. I should have bought it much sooner than I did. I've used it everyday and the sound is awesome. I love the ability to really sculp your sound all inside one plugin and the ability to blend the effect you've dialed in with the original source is worth the price alone.

Demon Fuzz

Demon fuzz is good on lots if different sources. I use mostly on my bass bus and also on synths sounds great. That said the ui could use an update nothing really negative to say at all.

Good Sound but the Interface could be much better

I think the versatility is very nice but the the poor quality of the picture of the stompbox, descriptions and the missing higher resolution window could be easly improved :-).
Today I have installed the bx_console AMEK 9099 and I'm really impressed by the really beautiful interface of the AMEK 9099 console, I mean the used version with fingerprints. Unbelivable. You get the feelings somehow like touching the real console.

A better higer resolution interface could be developed for JST Demon Fuzz soon. We do the music with our eyes too and change the parameters on the monitor.

God bless good music :-). Rafael

Crazy vesatility for a distortion Plugin

The variety is far beyond most distortion plugins. Well done!

JST Demon Fuzz

Great plugin! I'm actually using the BitCrusher effect on my Mid / High frequency signal for my bass track and it sounds amazing! 👌
