Longsword
$249
The Electronic Audio Experiments Longsword is yet another contender in the endless void of op-amp based drive pedals, but it is one that takes the topology in a novel direction. Cascaded gain stages allow for the full range from clean boost to massive distortion, all without sacrificing tonal flexibility. The equalizer combines bass and treble shelving filters with an active, frequency-selectable midrange boost/cut control. This lets the user sculpt a diverse array of tones and carve out a niche in even the most dense of mixes. The Longsword has a broad frequency response which makes it work equally well with guitar, baritone, and bass.

Electronic Audio Experiments Limelight V2 Overdrive/Boost
$249.00 – Sold Out
Electronic Audio Experiments Limelight V2
Limelight is a dual channel overdrive developed in collaboration with LA-based punk band Touche Amore. The distinctive bright, clear tones of guitarists Nick Steinhardt and Clayton Stevens form the foundation of TA’s impassioned brand of post-hardcore, letting their riffs morph effortlessly between serene clean passages and cacophonous blast beats. This pedal was originally developed to commemorate the release of their 2020 LP, Lament, but since earned its place in a wide variety of guitar rigs spanning genres.
In preparation for the recording of Lament, we worked with Nick and Clayton to create a new op amp overdrive with equal parts aggression and chime. While loosely based in the “breaker” lineage, we made significant changes to the circuit for superior articulation and a much wider range of gain. An independent front-end boost rounds out the package, perfect for adding power to clean tones or pushing the overdrive side into heavy distortion. While the primary goal was to help the band sound like their best selves, Limelight has a tone for everyone.
Controls:
Boost – adjusts the Boost channel from 0dB to +21dB of clean gain when turned clockwise.
Drive – Simultaneous control of two gain stages, with a natural midrange boost as you turn it clockwise. Achieves approximately 50dB at the maximum setting.
Tone – Adjustable low pass filter, clockwise for more treble and counterclockwise for less.
Volume – Output level control, turn clockwise for more volume.
Focus – Variable low cut in the drive section, adjusts the amount of chime and midrange presence.
Left footswitch – Engages drive circuit

Electronic Audio Experiments Dude Incredible V2
$299.00 – Sold Out
Dude Incredible V2
The Dude Incredible is a pairing of two cult classics: the IVP “Tube Voice” preamp and a percolator-style fuzz. Together, these two circuits have produced some of the most iconic guitar sounds in noise rock: jangly rhythm tones, ear-piercing treble chords, and endless walls of howling feedback. Originally released in 2017, the Dude Incredible was the first adaptation of the IVP into a pedal format. Now, it returns with some extra features and modern reliability improvements.
The Tube Voice channel is our streamlined version of the Intersound IVP (aka Instrument Voicing Preamp), a nearly-forgotten rackmount preamp from the 1970s. The transformer-loaded overdrive circuit is driven by a pre-gain shelving EQ for a distinctive palette of frequency-selective distorted sounds. Far from just a clang machine, this channel is fantastic for medium gain tones or as an always-on base layer. (This channel can also be found as a standalone unit in our Surveyor pedal.)
The Percolate channel needs no introduction. Our take on this beloved two-transistor fuzz features a painstakingly selected germanium transistor based on measurements of an original unit. We also added a diode switch to select between our custom configuration found in the Dude Incredible V1 and a more traditional highly compressed mode. Combining the Percolate side with the Tube Voice side produces a devastatingly destroyed fuzz.
Even if you aren’t a metal-pick-wielding treble fiend, the Dude Incredible is a source of unique distortion sounds that can’t be found anywhere else.

Electronic Audio Experiments 0xEAE Boost
$299.00 – Sold Out
0xEAE Boost
The 0xEAE Boost is the first entry in a new pedal series developed in conjunction with the design collective Obstructures.
The 0xEAE collaboration began as an indestructible enclosure created in the distinct, utilitarian-yet-elevated visual language of Obstructures, culminating in a neo-brutalist homage to the iconic sloped fuzz enclosures of the 60s and 70s.
The exterior physical design (and our shared affinity for noise rock) informed the intent of the circuitry within: a versatile signal boost/overdrive with the potential for a razor-sharp treble response and excessively high output levels. The circuit itself is comprised of a discrete op amp gain stage with a treble boost in front, forming a densely textured upper midrange character laden with higher order intermodulation products. A mix of active and passive tone controls allows for dramatic alterations in sonic character. We also took extreme measures to engineer a high-quality power supply that is fully protected from excessive voltage, improper setup, and external interference.
The end result is an object that is maximally robust, designed for a lifetime on the road, on stage, and in the studio.
Electronic Audio Experiments Halberd V2
$249.00
Halberd V2 - Finish TBD
The Electronic Audio Experiments Halberd is a discrete transistor overdrive circuit designed for the greatest possible dynamic range and note clarity. It fills a special niche our family of drive pedals—a medium-gain device with the harmonic fullness and grind of a much higher-gain pedal, one that stands apart from both the brazen buzz of op amp distortion and the smooth breakup of JFET amp emulations alike.
The Halberd’s character comes from over a dozen transistors working in harmony. It is familiar but unique, sitting somewhere between blown-up tweed and an overloaded console. Rather than resigning itself to transparency, it imparts its character in a collaborative fashion, responding in unique ways to different instruments and amplifiers but not without leaving its distinct fingerprints. And of course, it is equally at home on guitar, bass, and synthesizer.
Controls
-
Pre: This sets the overall signal gain. Lower settings impart light compression, then increasing amounts of clipping up to a fuzzy overdrive, depending on the Voice and Depth settings.
-
Depth: This is an adjustable low frequency shelving filter at the input, and is very interactive with the setting of the Pre control. It can be thought of as a second gain control affecting low frequencies only.
-
Tone: This is an adjustable high shelf cut at the output, helpful for taming harsher frequencies especially at high gain settings.
-
Post: This sets the overall output level, and is buffered for full transparency at all signal levels.
-
Voice: 3 position switch to set the overall drive character
-
Clang (up): increases gain in the upper midrange, for an aggressive sound and a sharp attack
-
Standard (middle): moderate gain with a gentle mid push; identical to Halberd V1
-
Deep (down): a full range gain boost with woolly saturation and a fuzzy note attack
-

Electronic Audio Experiments Dagger V2 White
$199.00
Dagger- Limited Edition White
$199
The Electronic Audio Experiments Dagger is a simplified and miniaturized iteration of our Longsword op amp drive. We streamlined the circuit into its core gain stages and dual band shelving EQ, for the ideal match of simplicity and flexibility.
The process of editorializing the Longsword circuit let us rexamine the quirks and unique rough edges of earlier versions. In particular, we noticed that at higher gain settings, the EQ can be used to further overdrive the output stage for extra piercing or fuzzy tones. While not a traditional use case, we fell back in love with that sound and incorporated those design elements into the Dagger. In addition to being a great fit for smaller pedal boards, the Dagger also stands on its own as a unique drive pedal.
Controls:
-
Volume: output volume, self explanatory
-
Drive: turn clockwise to increase the amount of overdrive
-
Low/High: James/Baxandall tone stack (shelving filters)
-
Shift (toggle): Adjusts the low frequency contour. Up produces a thicker sound, and down produces a tighter sound.

Electronic Audio Experiments Model FeT - Raw Aluminum
$249.00
Model feT
The Model feT is a transistor-based preamplifier designed around the legendary Sunn Model T amplifier. Those who have played the original know that while it excels at heavy tones when pushed, it is far more than just an amp for stoner rock and doom metal. In fact, on its own it is a fantastic mid-gain amplifier with a tone that is dark, yet clear and present—making it an exceptional pedal platform.
Most famous Model T tones come from putting a distortion or fuzz in front of the amp. Thus, the Model feT is designed to sound good on its own and with other pedals stacked in front. This pedal goes beyond the standard triode-to-JFET emulation approach with the inclusion of an emulated power amp. This broadens the range of gain and—in the true spirit of the original amp—allows for massive headroom and volume output. This greatly expands its capabilities beyond a typical drive pedal: the Model feT can be used directly into a power amp, cab simulation, or DAW.
Electrical Specifications
-
Bypass: Relay switching with true bypass
-
Input impedance @ 1 Khz: 500kΩ
-
Output impedance @ 1 Khz: 1kΩ
