Death By Audio Evil Filter Psycho Filter with Switchable Fuzz Pedal

Discover fearless sound design with the Death By Audio Evil Filter, a brutally expressive analogue filter pedal that redefines your tone. Combining ultra-precise filtering with aggressive fuzz and intense modulation capabilities, it empowers musicians and sound designers to transform their audio signal into thrilling new sonic forms.

Main Features

• Psychoanalogue filter with integrated fuzz circuit
• Ultra-accurate filter driven by a medical-grade IC chip
• Versatile filter modes: low pass, band pass, and high pass
• Capable of extreme resonance, self-oscillation, and octave artefacts
• Switchable fuzz types and inverted compression for dynamic textures
• Expression CV input for external modulation control
• Robust laser-etched metal enclosure

At the heart of the Evil Filter lies a medical-grade IC delivering precise, responsive filtering unmatched in fidelity. It handles everything from subtle filtering sweeps to intense self-oscillation and octave-up/down effects, creating wild, psychoactive textures that feel alive and unpredictable.

The onboard fuzz section deepens sonic innovation with a switchable fuzz style and inverted compression toggle, offering a spectrum from tight grit to chaotic saturation that responds dynamically to your playing style.

External control is enhanced via the EXP CV input, letting you modulate the filter cutoff frequency using expression pedals or synthesizers for rhythmic sweeps and experimental performances.

Filter Controls

• Filter Frequency: Adjusts cutoff frequency in Hz for precise tone shaping
• Filter Output: Controls volume from the filter section
• Filter Selector: Switches between low pass, band pass, and high pass filters
• Filter Resonance: Fine-tunes resonance, working alongside the resonance switch
• Resonance Switch: Toggles between normal and high resonance ranges, enabling self-oscillation at extreme settings

Fuzz Controls

• Fuzz Output: Controls fuzz section volume
• Fuzz Type Switch:
  • Lower setting delivers clean, driving fuzz
  • Higher setting unleashes aggressive, blooming, chaotic fuzz
• Inverted Compression Toggle: Creates darker, heavier fuzz textures
