Death By Audio Evil Filter Psycho Filter with Switchable Fuzz Pedal

The Death By Audio Evil Filter is a brutally expressive analogue filter pedal that pushes far beyond traditional tone shaping. Combining hyper precise filtering with aggressive fuzz and extreme modulation behaviour, the Evil Filter is designed for players and sound designers who want their signal twisted into entirely new forms.

Main Features

• Psycho analogue filter pedal with integrated fuzz
• Hyper precise filter powered by a medical grade IC chip
• Capable of extreme resonance, self oscillation, and octave artefacts
• Laser etched metal enclosure

At its core is a medical grade IC chip that delivers an exceptionally accurate and responsive filter unlike anything else on the market. From subtle sweeps to violent self oscillation, the Evil Filter can be driven past its limits into octave up and down artefacts, folding envelopes, and unstable, psychoactive textures. The result is a filter that feels alive, unpredictable, and endlessly inspiring.

The onboard Evil Fuzz circuit takes things even further, dragging your signal into darker sonic territory. With a switchable fuzz type and an inverted compression toggle, the fuzz section ranges from tight, driving grit to blooming, chaotic saturation that reacts dynamically to your playing.

For even deeper control, the Evil Filter features an EXP CV input, allowing the filter cutoff frequency to be controlled externally via an expression pedal or synthesizer. This makes it a powerful tool for rhythmic sweeps, synth style modulation, and experimental performance techniques.

Filter Controls

• Filter Freq: Sets the cutoff frequency of the filter, displayed in Hz
• Filter Output: Controls the output volume of the filter section
• Filter Selector: Switches between low pass, band pass, and high pass filter modes
• Filter Resonance: Adjusts filter resonance in conjunction with the resonance switch
• Resonance Switch: Selects between normal and high resonance ranges
  • Can self oscillate at extreme settings

Fuzz Controls

• Fuzz Output: Sets the output level of the fuzz section
• Fuzz Type Switch:
  • Lower setting for a cleaner, driving fuzz
  • Higher setting for an aggressive, blooming, and chaotic fuzz
• Inverted compression toggle for darker, heavier textures

Connectivity and Power

• EXP CV Input:
  • Accepts CV control from approximately 0 to 3.0 V
  • Compatible with expression pedals and synthesizers
  • Filter Freq knob sets the control range
• Powered by standard 9 V DC power supply or included 9 V battery
  • Centre negative
  • 2.1 mm connector
  • Approx. 21 mA current draw

Designed for Controlled Chaos

The Death By Audio Evil Filter is not a polite effects pedal. It is a fearless sound shaping tool built for experimentation, extreme textures, and boundary pushing performances. Whether you are sculpting surgical filter sweeps, unleashing oscillating noise, or blending fuzz into controlled madness, the Evil Filter offers a level of sonic control that few pedals dare to approach.
