EarthQuaker Devices Afterneath Eurorack Module

Bring the shimmery sounds of the Afterneath guitar reverb pedal to your modular synth setup with this unique Eurorack module from EarthQuaker Devices.

The Afterneath Eurorack Module brings the otherworldly sounds from the effects pedal world right into your modular synthesizer with an expanded feature set. The Afterneath Module features one main audio input, one main audio output, an audio send and return for the Reflect feedback path, and nine controls. Four of the parameters are controllable via CV, and each has been equipped with a dedicated inverting attenuator. The Afterneath module has a completely analog dry signal path and a totally digital wet signal path.

The Afterneath Module further expands upon EarthQuaker's wildly popular Afterneath pedal with the addition of voltage control over the Diffuse, Length and Drag controls. We have also added an entirely new voltage-controlled "Mode" parameter that changes how the Drag responds to knob and CV changes.

When adjusting the Drag via the knob or CV, you will notice a change in character, fidelity and decay length of the effect. There is also a noticeable change in pitch for the sound that is in the Afterneath's buffer. As with the Afterneath pedal, high settings of the Reflect and Length controls result in self-oscillation, where the pitch of the oscillation is set by the Drag control. There are nine modes that govern the behavior of the Drag control and its effect on the pitch of the sound in the buffer:


Smooth, unquantized response over the entire operating range of the read more Drag parameter.

Unquantized with Slew:

Smooth, unquantized response over the entire operating range, but with a musical slew that is reminiscent of turning the varispeed knob on a vintage British tape delay. The "Drag" will lag behind the knob or CV changes, but then quickly catch up.

Unquantized Volt/Octave:

Smooth and unquantized, yet scaled to align with the 1V/octave curve to allow melodic modulation of audio in the buffer, or control the frequency of self-oscillation like a voltage-controlled oscillator.

Chromatic Scale:

Quantized to 1V/octave, so that it jumps to intervals within the Chromatic scale.

Major Scale:

Quantized to 1V/octave, so that it jumps to intervals within the Major scale.

Minor Scale:

Quantized to 1V/octave, so that it jumps to intervals within the Minor scale.

Pentatonic Scale:

Quantized to 1V/octave, so that it jumps to intervals within the Pentatonic scale.

Octaves and Fifths:

Quantized to 1V/octave, so that it jumps to octaves and fifths of the original pitch.


Quantized to 1V/octave, so that it jumps to octaves of the original pitch.

Beyond modulated delay and reverb effects, modes 3-9 extend the possibility of using the Afterneath Module as an interesting voltage-controlled oscillator. Another new feature found only in the Afterneath Module is a Dry Kill switch that allows access to a 100% wet signal. Perfect for when you are using the module as an effect send from your mixer or digital audio workstation!

Last, but certainly not least, we have added a Reflect Send and Reflect Return jack. This not only allows external processing of the Afterneath's Reflect feedback path, but also gives the user access to a phenomenal pseudo-stereo effect. In addition to patching from the main output, you can also patch from Reflect Send jack (For example, using the main audio output as your left channel, and the Reflect Send as your right channel). This provides a wide, immersive, ambient stereo image. This is a great trick for when using the module as an effects send for your favorite modular, mixer or DAW. Additionally, the Reflect Return jack can be used as an additional audio input. The Reflect knob will act as an attenuator for any signal that is patched into the Reflect jack.

The new features in the Afterneath module transform the original Afterneath into an ambient powerhouse and an instrument unto itself.


- Same otherworldly reverb algorithm built from an adjustable cluster of short delays in a 16HP Eurorack format
- Ranges from scattered individual delays to an immersive wash of atmospheric reverb
- New voltage control over the Drag parameter with 9 unique modes of user-selectable sweep: Unquantized, Unquantized with Slew, Unquantized Volt/Octave, Chromatic, Major, Minor, Pentatonic, Octaves & Fifths, Octaves. These new modes of operation push the already unbeatable Afterneath into a whole new realm.
- Features audio send and return for the Reflect feedback path
- Drag, Mode, Diffuse, and Length parameters are controllable via CV, each with dedicated inverting attenuators
- Features Dry Kill switch to eliminate the dry signal from the output, leaving only the wet signal
- Capable of pseudo-stereo operation by using the Reflect Send as an additional output
- All analog dry signal path and a totally digital effect signal path

The Afterneath reverb by Earthquaker Devices is well known amongst guitarists for its lush reverberation and unique design. It throws out an explosion of short delays with controls to: separate and smooth out delay repeats for a huge wash of reverb (Drag & Diffuse), adjust tone (Dampen), Length, and reverb regeneration (Reflect). But this is the eurorack version and we get extra control! The Drag input can take v/oct. signals allowing for direct control over the pitch of the reverberation. Turning the Reflect and Length up can put the Afterneath into self-oscillation allowing it to be used as an oscillator. Which is mostly successful. A fun little extra as opposed to something I would use regularly. The Mode knob has 9 different v/oct., quantization, and scale settings so you can have alot of fun playing with the Drag. I've used a manual gate button to advance an analog step sequencer which then changed the reverb pitch. Great for tinkering with ambiance! Processing the Reflect feedback (reverb regeneration) is also a neat experience but it highly depends on the settings and the external processor. Overall, it's a highly playable and unique reverb. Recommended for people that want to experiment with their reverbs or people that like enormous ambient space verbs. Not necessarily for people that want super short, clean, room reverbs. I would have liked a highpass filter over everything (not just Reflect/regeneration processing) to easily create shimmery verbs and CV control over read more Mix. Oh, and a fancy Earthquaker Wizard graphic over the entire panel like the pedal version! But oh well. It's already awesome!
