The Electronic Audio Experiments Citadel is a preamp-style overdrive inspired by the everlasting sounds of British amplifiers from the '60s and '70s. Rather than emulating a specific model, it encompasses our favorite parts of a whole generation of amplifiers including warm piano-like cleans, bright clear overdrive, and sizzling lead tones.

The Citadel began as a series of experiments on our Model feT pedal. Like any tube amp, there are ample opportunities for modifications. After all, the original Model T was itself a modified take on the Super Bass sound, delivering a distinct variety of the plexi flavor with fuzzy breakup and a huge low frequency punch. So, what if we flavored it our own way? Once Brad completed his "Marsha" prototype, it was on. In a way, you can almost think of the Citadel as a re-plexi-fied Model T sound, trading low end sludge for a sparkly midrange focus. In another way, you can think of it as what we’d do if the original Model T wasn’t too sacrosanct to modify.

Finally, like our Model feT, the Citadel emulates both the preamp and power amp sections of a tube amp to provide a full-bodied overdrive that feels powerful and responds wonderfully to boosts, drives, and fuzzes in front. It can be used either a conventional drive pedal or as the workhorse of an ampless signal chain.

The Electronic Audio Experiments Surveyor is a compact interpretation of the Intersound IVP (Instrument Voicing Preamp), a cult classic rackmount preamplifier used for famous noise rock tones. This 4-knob drive was previously found in the left half of our Dude Incredible pedal, and it is now available on its own in a more compact and affordable format. 

The original IVP is best known for its distinctively clangy tone with the treble cranked, especially in conjunction with aluminum guitars and full range speakers. But it is far from a one-trick pony. Thanks to its 2-band active EQ and unique "Tube Voice" clipping circuitry, the IVP can sculpt all kinds of uniquely saturated textures that transcend genre labels.

Surveyor

Sending is an analog delay that melds the archaic voice of bucket brigade devices with a fully modern toolbox of digital control. It embraces the character and idiosyncrasies of the medium while delivering high quality sound and performance-friendly features worthy of the modern musician.

Using two MN3005 BBDs and comprehensive analog processing techniques, Sending can delay a sound up to a full second without clock noise, and it can be pushed to even longer times for compelling sonic degradation. At the input is a discrete preamplifier capable of subtle enhancement or warm saturation that melds perfectly with the delay line. A dual-mode feedback filter shapes the repeats into deep pulses or dub-style bright echoes. Its flexible LFO engine can modulate the delay time to create gentle movement or musical chaos. Conducting this analog ensemble is a 32-bit, 100MHz processor granting deep user control, preset functionality, and MIDI access to every parameter.

Sending is our love letter to the antiquated yet enduring technology of analog delay. As you explore its many shades of interplay between past and future, we hope you find it as immersive as we do.

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.

Dagger v2

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.
