Icicle Equalizer is your ally for surgically removing any annoying frequency or increasing a region.
Edit without limits!
With Icicle Equalizer you can choose between our cleanest sound, or a more coloured sound with the OOMPH!


Clean sound

Ultra-clear and clean sound, perfect for equalising voices, guitars or strings.


OOMPH! sound

Perfect to add a special colour to your tracks, from the characteristic grain of tape recording, to higher levels of distortion giving a unique personality to your drums and basses.


Benefit from the OOMPH! feature

Icicle Equalizer is empowered to add extra analogue colour thanks to Germanium Diodes distortion.

OOMPH! will grant your sound with the harmonic’s excitation from a slightly soft distortion to an aggressive one. Perfect for all those situations where you are looking for that kind of rich and warm sound.


Broaden your voices

Sure enough, you have envied the broadened voices of your favourite mixes a million times.
Icicle Equalizer comes with a treble filter that reaches up to 29,4kHz.
Therefore, you will be able to enhance your voices’ glow up to the maximum, adding a sense of broadness and proximity.
Want better results? Try the treble bandwidth with a lowered Q to reduce the annoying frequencies and control de Harsh effect.


Down to the last detail

Icicle Equalizer fits perfectly those situations where some annoying frequencies arise, either due to an acoustic space resonance, to the instrument construction, or because of the presence of certain frequency registries unneeded in the final mix.
To get rid of them, we suggest choosing a small Q and increasing that frequency range gain. Search for the said frequency adjusting the FREQUENCY knob until noticing it intensifies. Beware of keeping your monitor’s volume not too high.
Once found, decrease the gain to the minimum and… Voilà! The frequency will vanish.


Boost your FX

Do not leave your delivery channels untreated. The reverb channel often contains unnecessary frequencies that soil the final sound. Icicle Equalizer is ideal for these situations.
Try removing the effects’ low-end or even eliciting a different sensation by creatively emphasizing different ranges of frequencies.



Tierra Green – Growing forests with your sound

TIERRA Green is born, and with it our firm compromise to plant a tree for every device that will be sold.
For the time being we have bought 30.000 square meters of fertile land located in the north of Spain, where we do wish to one day grow a forest.

10 Reasons to test it!

Handmade with love in Madrid

In order to guarantee the correct electron flux of the analogue signal, we put together the finest “through hole” components, instead of robotically assembled miniaturized components. In this way we reduce to the minimum the electronic friction to enhance the thermal response of the equipment and avoid background noises.


Triad Magnetics® transformer

Every Icicle Equalizer is equipped with an original Triad Magnetics® transformer to nurture the power stage, thus providing a more stable, precise, and lasting result, that does not generate any type of noise.


VU meter

Each Icicle Equalizer also contains one excellent VU meter so that you can accurately control the gain levels of the analog signal.


Gold plated connectors

When speaking about true ProAudio, all the links of the recording chain are fundamental. Gold plated connectors guarantee the best connectivity, and a total absence of contact noise as well. A real piece of jewelry in your hands.


Made of pure cherry wood

A picture is worth a thousand words. So, we wanted to ensure that you will know that your Icicle Equalizer has the makings of a champion only by looking at it. Finished with a warm and resistant natural cherry wood paneling, from sustainable forests, we ensure better thermal insulation and surprising aesthetics. Technology and art in a superb symbiosis.


Light and robust

By building our products in aluminium, we ensure the highest durability, lightness, corrosion resistance, and thermal insulation. Besides all this, aluminium is an easily recyclable metal that always retains its properties, avoiding indiscriminate exploitation. Makes sense, doesn’t it?


Paulownia packaging

Despite its lightness, Paulownia (or Kiri) wood is very impact and twisting resistant. This allows us to protect your device and reduce pollutant emissions during the shipping process. It is also very resistant to moisture, ideal for device protection. On the other hand, Paulownia is the fastest growing tree which makes it a very sustainable option.

Branded by fire

We want you to use your Icicle Equalizer intensively for decades. That is the reason why the frontal and back panels are laser engraved, avoiding deletion or damage of the screen printing over metal or wood, through time.


Certified authenticity and quality

With your Icicle Equalizer, you will get a Certificate of Authenticity and Quality, sealed and signed by hand, that contains the results of the technical measurements conducted over the equipment during our extensive quality control. Thoroughness, transparency, and a 5-years warranty.
