The Dedalo Fx Atenas is a reverb pedal built around an unusual idea: a spring reverb tank made from digital delays running in an analog feedback circuit, in the manner of the maker's MDT Delay. An 8-bit digital buffer feeds the reverb in parallel with the analog signal, and a tone control sits ahead of it. Dedalo Fx, an Argentinian brand of pedals, describes the Atenas as a "reverb generating machine" and says its 8-bit technology "reduces fidelity and invokes strange landscapes and octave sounds, as well as distant drones with the Freeze modes."1
It is a lo-fi take on reverb rather than a realistic room or hall simulator, and it sits among reverb pedals as an effects tool for texture and ambience. The pedal is model ATN1, dated 2023.1
How the circuit works
The Atenas is not a straightforward digital reverb. Dedalo Fx describes it as a spring reverb tank built from digital delays inside an analog feedback circuit, similar in approach to the maker's MDT Delay. A tone control precedes the tank, and an 8-bit digital buffer feeds the reverb in parallel with the analog signal, with the Source Mix control setting that balance.1
The 8-bit section is deliberately low fidelity. Its buffer size runs from 37ms to 147ms, and its sampling frequency runs from 10.4Khz to 2.6Khz. Dedalo Fx says this is what generates the pedal's "ecstatic waves of reverb" and its stranger textures, from octave-like sounds to distant drones in the Freeze modes.1
The dry path stays analog: the pedal has an Analog Dry-Thru with a Dry/Wet mix control.1
Controls
| Control | What it does |
|---|---|
| MIX | Blends the clean (dry) signal with the reverb (wet). At maximum it is completely wet, which Dedalo Fx calls ideal for generating ambiance and using the pedal in parallel as an fx send.1 |
| TRUE BYPASS switch | Turns the effect on and off; in True Bypass the sound stays intact when the effect is off.1 |
The pedal offers two bypass behaviors: Bypass with tails, which lets the reverb decay naturally after switching off, and True Bypass.1
Power and connections
The Atenas runs on a DC 9V center negative supply and draws 94mA at 9V DC. Input impedance is 700Kohm.1
At 94mA, the Atenas draws more current than many compact pedals. A low-current daisy chain or a battery-style supply may not run it; use a supply that can deliver at least 94mA at 9V DC.1
Price, shipping and warranty
Dedalo Fx lists the Atenas at 165 USD plus shipping, and ships by FEDEX International Priority, which takes 7 days to most places. The maker notes shipping is not available in the United Kingdom. The pedal carries a 2-year warranty; the maker states that all its products are covered under a two year guarantee, and lists info@dedalofx.com.ar for questions.1
The enclosure is turquoise, measuring 12cm x 9.4cm x 5.4cm and weighing 480gr.1

Questions
Does the Dedalo Fx Atenas have true bypass?
Yes. The Atenas offers both Bypass with tails and True Bypass. The True Bypass switch turns the effect on and off and keeps your sound intact when the effect is off, according to Dedalo Fx. The bypass with tails option lets reverb rings out naturally after you switch the effect off, which many players prefer for ambient playing.
What power does the Dedalo Fx Atenas need?
The Atenas runs on a DC 9V center negative power supply and draws 94mA at 9V DC. Because of the current draw, check that your power supply or daisy chain can supply enough current for it alongside your other pedals.
Is the Dedalo Fx Atenas analog or digital?
It is a hybrid. At its core is a spring reverb tank that uses digital delays in an analog feedback circuit, with an 8-bit digital buffer feeding the reverb in parallel with the analog signal. The dry path is analog, with an Analog Dry-Thru and a Dry/Wet mix control.
How much does the Dedalo Fx Atenas cost?
Dedalo Fx lists the Atenas at 165 USD plus shipping, as of the maker's product page dated October 2026.
Does Dedalo Fx ship to the United States?
Yes. Dedalo Fx ships by FEDEX International Priority, which takes 7 days to most places. The maker notes shipping is not available in the United Kingdom. For questions, the maker lists info@dedalofx.com.ar as its contact email.
What warranty does the Dedalo Fx Atenas have?
Dedalo Fx covers the Atenas with a 2-year warranty. The maker states that all its products are covered under a two year guarantee.
