Neunaber Audio Effects

Beautiful Sounding Little Algorithms

Reverb, Chorus, Delay and Drive of the highest standard

Neunaber Audio Effects is a family-run company from Orange, California started by Brian Neunaber in 2009. The brand designs and manufactures effects pedals for the discerning musician with simple yet surprisingly versatile and beautiful sounding reverb and chorus pedals.

Previously the DSP Architect at QSC Audio, Brian Neunaber has been designing audio products professionally since 1994. While at QSC, he helped to develop and implement several key processing technologies found in QSC’s K Series and other products. Prior to QSC Brian designed effects processors and a digital modelling guitar amplifier for St. Louis Music, who marketed products under the Crate and Ampeg brands.

Today Neunaber state they are not a mass-producer, nor do they see themselves as “boutique”, however the company strives to practice the best from each approach preferring to remain small and agile and designing using modern assembly techniques for maximum value and consistency using the best parts and practices, but only when it results in a noticeable improvement in sound, appearance, or longevity.

With such well received and desirable pedals like the Immerse V2 reverb, the Inspire Tri-Chorus, the Expanse to the Neuron Gain Intelligence, Neunaber believe that making great products is the best marketing strategy and they rely primarily on happy customers to spread the word.

Immerse V2 Reverberator Pedal

8 Magical Stereo Reverbs in one Compact Pedal

With richer reverbs and a Mix knob that goes 100% wet, the Immerse Mk II is Neunaber’s best-sounding reverberator to date. Delivering the same no-nonsense flexibility as its predecessor, it’s more user-friendly than ever before.

Experience studio-quality tone in a pedal that can be used with instruments of all stripes. The Immerse Mk II is packed with eight versatile reverb effects, including the new W3T andSustain effect and can be used with instruments of all stripes.

  • W3T (Wet version 3): Exclusive to the Mk II, Neunaber’s new flagship reverb is smoother and more three-dimensional sounding than ever before. Now with adjustable pre-delay, it enhances what you play without covering it.
  • Plate: Bright and diffuse like a studio plate reverb.
  • Hall: The lush, open sound of a concert hall, now with adjustable modulation depth for achieving deep modulated tones.
    Spring: The distinctive twerp of a tube-driven spring reverb. Now with adjustable modulation speed, it can achieve a vibrato-spring sound.
  • Sustain: A new algorithm built on the W3T reverb. This magical, versatile effect can be configured as a sustainer or infinite reverb.
  • Echo: Combines the W3T reverb with stereo echo.
  • Detune: Adds a detuned double of the dry signal with reverb, now with true blend control between detune and detuned reverb.
  • Shimmer: Reminiscent of a synth pad that follows what your instrument plays, this effect combines the best qualities of Neunaber’s shimmers.


  • High-quality buffered bypass with external Trails switch
  • External Kill Dry switch for parallel effect loops
  • Inputs/outputs can be used mono or stereo
  • Analog dry signal for low noise and zero latency
  • Small, pedalboard-friendly footprint.
  • Requires standard 9V or 12V PSU
  • Designed and manufactured in California USA

Inspire Tri-Chorus Plus

Complete & Intuitive Chorus

Those magically lush, elusive chorus tones are finally within reach… without a rack of expensive gear.

Inspire captures eight stunning chorus effects – ranging from subtle to incredibly lush – all built around variations of Neunaber’s tri-chorus algorithm and are selectable via the Effect Selector.

Inspire’s newly-designed circuitry offers increased headroom while maintaining low noise.

A numerically-optimised analog mix control results in unity-gain dry/wet blend throughout the range, from 100% dry to 100% effect. Inspire also features relay true bypass, stereo inputs & outputs which an also be used in mono, an all analog dry signal for low noise and zero latency.

It is pedalboard-friendly thanks to its small footprint and requires standard 9V or 12V pedal power supply.

Like all Neunaber products, it is designed and manufactured in California, USA.


Containing the beautiful-sounding angelic ambient reverbs and divine delays that started the Neunaber legacy, the Expanse contains a direct digital portal to all of the iconic Neunaber algorithms, while adding a ton of new algorithms as well to the party. This lets you load whatever sound you want into this blank-canvas-pedal.

Want that classic WET Reverb? You got it! Or how about a lush Tri-Chorus? Or maybe a Tremolo, Flanger or Phaser? It’s all there and then some and all easily ported to the pedal via the free Expanse Editor.

Plus, with the separate EXP controller, the pedal is quickly turned into a tiny but powerful 8 preset multi-fx unit that’ll take any pedalboard to next level.


Versatile preamp pedal with presets & MIDI

Neuron achieves a seamless array of incredible amp tones in a compact pedal – from sparkling clean to heavy distortion and everything in between. A multistage, dynamic gain architecture yields unparalleled control over the desired amount of distortion – effortlessly producing harmonic structures that range from subtle to dense and complex. One of its most salient features is its feel, which is almost hyper-realistic when compared to an amplifier.


  • Integrated compressor constrains the drive level for smooth, consistent tone. • Adjustable studio-quality noise gate keeps your signal quiet.
  • Tilt EQ adapts your tone to various setups without changing presets.
  • Defeatable speaker simulator for running direct.
  • Three-band EQ with tightness and presence enables a plethora of tonal options.
  • Up to 6 presets can be stored for quick recall via the footswitch. Up to 24 presets can be recalled using a MIDI controller.
  • All controls are accessible using a MIDI controller.

Company founder, Brian Neunaber states “Neuron is the culmination of years of research and development. We studied the gain circuits of both tube and solid state pedals and amps to learn, not only how they sound good, but why. We developed new and unique algorithms to test our findings, then refined these algorithms based on what we learned.”
