Dystorpia#

Futuristic Fuzz, Dystopian Distortion, Overdrive Oblivion

Overview#

Dystorpia is Noise Engineering’s digital fuzz/overdrive pedal designed to provide a vast array of distorted tonalities from traditional to futuristic. Utilizing wavefolding and rectification signal-processing techniques not typically used in pedals, Dystorpia will give you the ability to dial in unique, ripping, and gritty sounds unobtainable with traditional overdrive circuits.

Power#

To power your Noise Engineering pedal, use a 2.1mm 9 VDC negative center power supply with a minimum of 250mA. For best results and lowest noise, use a dedicated transformer isolated power supply.

Interface#

A top-down view of Dystorpia

Gain
Sets the input signal level going into the rest of the circuit. This helps find the sweet spot for a variety of source inputs. For guitars with lower output pickups, you may want the Gain set higher. For high output pickups, try setting the Gain lower. Experiment to get the tonalities that sound best to you. Altering the Gain can change how the signal is affected by the processing.

Note

To adjust the output gain of the pedal, hold down the left Freeze footswitch and adjust the Gain control.

Fold
Sets the amount of wavefolding applied to the signal. Wavefolding folds a signal down when it passes a threshold instead of clipping it. This gives a distinct flavor of harmonic distortion. Increase Fold for a gritty, hashy, growling texture. Blending Fold with Pura at various settings offers a vast variety of tones.
Blend
Blends the dry input signal with the affected signal. All the way left is only the dry signal, and all the way to the right is only the affected signal. Unlike most blend controls, Dystorpia’s unique Blend knob applies some mild saturation to the dry signal as the knob is turned to the right. The saturation retains chord information and articulation, but allows the signal to mix in with the affected signal without sounding clean.

Note

The Mid Band and Tone controls are applied the dry signal when the pedal is engaged, and will affect the dry signal regardless of Blend setting.

Pura
Sets the amount of full-wave rectification applied to the signal. This shifts the negative part of the waveform to the positive, resulting in a harmonically rich, buzzsaw fuzz. Experiment with different amounts of Fold and Pura for unique tonalities.
Mid Band
Sets the frequency of the mid band. Experiment with Mid Band and Tone for complete control over the resulting tone.
Tone
Sets the basic tone, from bassy to high. At the very top of the knob range, lows are boosted along with the highs for a mid-scooped sound. This leaves lots of room in the mid range to play with the Mid Band control.

Note

The Tone knob is mapped to the EXP expression pedal jack allowing for wah-wah style control. With an expression pedal plugged in, the Tone knob sets the lowest value the expression pedal will go to (in heel-down position). If you want the expression pedal to cover the entire Tone range, turn the Tone knob all the way down. If your expression pedal has a range knob, you can use it to set the Tone setting you want the pedal to reach in the toe-down position.

Doom
Adds some doom to your sound.
  • Off: No doom is added.
  • Sub: Adds a lower octave to the signal.
  • Blown: Adds a lower octave at a higher volume than Sub, and the rumbling tonaility of a blown sub speaker. These interact with Fold and Pura.

Note

Doom works best with single note runs.

Env
Sets the style of dynamics.
  • Off: No change; dynamics behave like a traditional distortion pedal.
  • Dyn: A dynamic envelope that will shape the output volume level to match the clean input volume. This will allow for very dynamic playing; playing quieter will retain the tonal characteristics added by the distortion algorithms, but the output will be reduced to match the input. This setting will also have a shorter sustain, since the output level is derived from the clean signal. This can be useful for players who wish to achieve the dynamic behavior of a clean guitar, but with a distorted sound.
  • Gate: Adds a smart noise gate that drastically lowers the output level when there is no input signal. By adjusting the Gain setting, hum can be virtually eliminated when you are not playing. This setting allows for more sustain, but reduces noise at the tail.
Freeze (left footswitch)
Sustains a short loop of whatever you last played. Quick tap to latch and unlatch, or hold down for momentary-style behavior.
Bypass (right footswitch)
This is a buffered bypass which will engage or disengage the effect.
Input
¼” mono input
Output
¼” mono output
EXP
Input for Expression pedal or control voltage. ¼” TRS expression pedal connection jack or ¼” TS connection for control voltage. The expression input affects the Tone control. If using control voltage, the input responds to 0 to 5V and adds to the position of the Tone knob.

Note

If using an expression pedal, only a standard TRS expression connection should be used with Dystorpia.

9V
2.1mm power connection for 9VDC negative center power supply, 250mA minimum.

Settings Examples#

POWER CHORD BUZZSAW
A chunky, thick, and heavy go-to sound that works really well with power chords, especially when playing four-note power chords with the root on the A string, the lower 5th added on the E string, upper 5th on the D string, and the octave on the G string.

#

BUZZSAW WAH (with Expression pedal)
Same as above, but with an expression pedal plugged into EXP and the Tone knob all the way down. This allows for the expression pedal to sweep the entire range of the Tone knob for incredible wah-style sounds. Play with the Mid Band setting to vary the color of the wah sweep. If you do not want the mid-scooped option at the top of the expression range, slightly turn down the pot on your expression pedal (if it has one).

#

60s OCTAVE FUZZ
A vintage sounding fuzz tone with a lower octave. This is great for 60s soundtrack style single note runs, riffs, and leads.

#

explanation'

DYNAMIC DISTORTION
This makes use of the ENV Dyn setting, which allows for you to control the volume with your playing while retaining a consistently chunky distorted tone. Cool for dynamic rhythm or lead playing.

#

SEEK AND DESTROY
An abrasive, brutal, garage rock setting that will slash through the mix.

#

SLIME GRIME
A boxy, liquid, grimy sound that reacts to the dynamics in an animated way, imparting a strange, modulated sort of sound.

Design Notes#

Even though Dystorpia is a digital pedal, the design was highly informed and influenced by many hours of research building and testing discrete analog circuits. The Pura and Fold parameters are adaptations of controls of the same name found on some Noise Engineering Eurorack modules.

Dystorpia is designed and built in sunny Southern California.
