Seymour Duncan Fooz offers you fuzz, modulation, and control — with an all analog signal-path, designed to synthesize the ultimate fuzz tone.

Many guitar or bass pedals can make your sound like a synth, but few capture the tactile feeling and interactivity of using one. Real analog synths use different blocks (oscillator, filter, LFO, envelope) that work together to create unique new sounds and textures. Combining these tools in one box and allowing them to interact with each other is the spirit of the Fooz

Fooz uses a heavily saturated square-wave fuzz to transform your guitar or bass into the ‘oscillator’, ready to be sculpted by other blocks—it also makes for a great fuzz tone by itself. The next element is the Filter which can be set to a Low Pass Filter (based on what you’d find in classic synths) or a Band Pass Filter which works more like a Wah pedal. Finally, a deeply tweakable LFO and an Envelope follower provide the modulation. The LFO can be used to control the overall volume and Filter Frequency. The Envelope can control the Filter and the LFO Depth and Rate. You can also control most of the surface controls with an external expression pedal (not included).

The interconnectivity between blocks allows the Fooz to be used in a variety of manners. You can use it to replicate the sounds of a synth but also as a straight-up fuzz, tremolo (use the LFO to modulate the volume), auto-wah (use the Envelope to modulate the Filter), fuzz-wah (expression pedal assigned to control the BPF), rhythmic filter (LFO assigned to Filter Frequency), or a “cocked” wah (no modulation, BPF set to desired frequency).

Using the dip switches on the rear allows for even more interactivity:
ENV > LFO Depth

  1. ENV > LFO Rate
  2. Invert ENV Polarity
  3. Invert EXP Polarity
  4. EXP > Volume
  5. EXP > Freq
  6. EXP > LFO Rate
  7. EXP > LFO Depth

Seymour Duncan calls it an Analog Fuzz Synthesizer. Inspired by iconic tones and synth flexibility, Fooz brings the spirit of synth creativity to guitars and basses.
