The Tierra Audio Icicle Equaliser is a powerful 4-band monoparametric equaliser designed as a versatile solution for any recording or mixing scenario. It provides the flexibility to surgically remove problematic frequencies, enhance tonal regions, or creatively shape the sound with pristine precision or rich analogue colour.
With two selectable operating modes, the CLEAN mode delivers an ultra-clear, transparent response ideal for vocals, guitars and strings, while the OOMPH mode introduces warm harmonic character through germanium diode distortion, offering anything from subtle saturation reminiscent of tape to aggressive drive perfect for bass and drums.
With a treble filter that extends up to 29.4 kHz, the Tierra Audio Icicle Equaliser brings openness and clarity to voices, while its adjustable Q allows precise control of harsh frequencies. Its design makes it an invaluable tool for addressing room resonances, instrument tonal imbalances, and mix artefacts. Beyond mono recording, the Tierra Audio Icicle Equalizer is also calibrated for stereo applications, with perfectly matched component pairs ensuring identical performance across two units. This allows professional engineers to apply consistent equalisation during stereo recording, mixing, and mastering.
Every Tierra Audio Icicle Equaliser is handmade in Madrid using high-grade through-hole components for optimal analogue signal integrity and low noise. It features a Triad Magnetics transformer in the power stage for stable and noise-free operation, a precision VU meter for level monitoring, and gold-plated connectors for uncompromised signal flow.
Its cherry wood housing from sustainable sources provides thermal insulation and elegant aesthetics, while recycled FSC-certified cardboard packaging protects the unit in transit. Laser-engraved panels ensure long-lasting durability, and each unit is shipped with a hand-signed certificate of authenticity and a 5-year warranty. To reinforce its commitment to sustainability, the company plants a tree for every Tierra Audio Icicle Equaliser sold.
