259.00

CompIQ Stella Pro is the one-of-a-kind compressor pedal that will blow your mind with the amount of control and versatility it provides. Packed in a compact, small-sized, road-worthy black-powdered aluminum enclosure, it is the smartest addition possible, to any pedalboard, small or big.

Guitar Magazine Editor's Choice - We’ve seen rackmount studio compressors with fewer controls than this little pedal from Romanian maker Becos.Notes are thickened without thumping, and chords gel together in a way that makes you sound like a better player. This is a proper gem.

With features only found in expensive studio rack gear, this stellar compression effect pedal is ready for professional audio dynamic processing, ensuring the musical response and transparency of analog circuitry.

Description

Studio-level audio performance in a pedal format

The CompIQ STELLA Pro Compressor is an all-analog, battery-operated, compressor pedal designed for guitar and bass and hand-built around the top-class THAT Corp. 4320 Analog Engine® – the same technology used in rack compressors made by the likes of DBX, Presonus, Dangerous Music or Revive Audio. A true RMS-level detector measures input signal and applies accurate feed-forward compression through a transparent sounding, high-performance Blackmer® VCA. The amount of control it offers is staggering and probably never before seen in a compression pedal, especially of this size. We didn’t leave out anything that helps to bring out a truly clean, accurate and transparent dynamic processing.

Full control over compression parameters

Becos CompIQ Pro Stella Compressor wet-dry-mix close-upWith so many controls, one may wonder how can this be tamed and furthermore, properly used in a live setup. Don’t let yourself overwhelmed. We provided sufficient options not only for in-depth control but also for making things easier. For instance, with the flip of a switch, you can take out the Manual Attack & Release controls (the most daunting of the art of compression) and let the Dynamic Auto Timing analog circuit do the right thing for you. Two choices are available for here, Fast or Slower timings, and both respond gracefully to any playing style. In both settings, transients are handled faster while steady signals benefit from longer release timings.

However, using the manual control of Attack and Release timings will expand the compression flavors by an order of magnitude. To mention just a simple trick: delay the attack time a little while bringing back a faster release time and you will end up with a punchy and proper sound for country chicken pickin’ or for instrumental stand-out soloing. Combine this with the Side Chain Filter and the Tilt-EQ and increase your options even further. All these together will also remind you of an optical-soul type of compression, demonstrating the tremendous versatility of this pedal.

The full-scale Ratio (1:1 to infinite:1), the instrument to line-level Threshold (-40dB to +10dB) range, and up to +20dB of Makeup Gain, all in continuous controls, add to the plethora of switchable options to further attain the ideal compression for any musical program.

A Dry/Wet Mix allows for parallel compression (a.k.a. the New York style), where the desired amount of unprocessed input signal is mixed with the compressed signal, for a more natural effect application.

Compression subtleties

Becos CompIQ Pro Stella Compressor threshold led close-upAdditional features are available for the very demanding players. The Side Chain Filter has three selectable options – Normal, Low and Deep -, very helpful for bass instruments or when a fuller output is needed. To keep things simple, set the filter to Normal and the compressor will just act naturally in most instances. The Normal side-chain processing presents a non-linear, high-pass characteristic above 1KHz, which balances the potential trigger-difference between the energy of low and high frequency. Such a feature is usually available only in high-end studio compressors, and it is intended for a natural effect application even on higher compression ratios. If lower-frequency notes trigger compression yet too fast, then the Low (-12dB@90Hz) or Deep (-12dB@200Hz) high-pass filters will slightly delay the compression, freeing up the low-end just enough for the spectrum to breath out and prevent the early or over-compression of highs.

The Compression Knee can be selected between Hard and Soft, each option having its own sonic signature. Hard Knee compression acts fast and squishes hard. Use this if you aim for limiting or in-your-face compression effect. Soft Knee compression acts progressive and gentle, helping to create a transparent effect application, even at the highest ratio.

The Tilt-EQ gentle equalization circuit has two selectable options for pivot frequency – High (at 1KHz) proper for guitar and Low (at 330Hz) suitable for bass. This is a post-compression applied correction, that can be either necessary for compensating from one instrument to another, or desired, for your particular sonic signature.

Harmonic coloring

Becos CompIQ Pro Stella Compressor controls close-upOn top of all these, we added an analog Saturation circuit which can add harmonic distortions to the dry line (only), which can then be mixed with the compressed wet line, for precise balancing of the effect. This circuit rivals the vintage studio tape-overload compression effect which was a studio recording trick during the ’60s. Tape saturation is a pleasing sort of distortion arising when high amplitude audio signals are recorded on magnetic tape.

The Saturation control can vary in intensity from nothing to mild and up to warm but powerful overdrive. The result is either subtle, adding richness to the sound peaks, or obvious, with a tube-like screaming distortion feel when all audio spectrum is saturated. If needed, Low and High-frequency cut filters can be engaged by removing two internal jumpers. This helps eliminate oversaturated low-frequency fuzziness or prevent high-frequency from sounding too pointy. The auxiliary Level control on the dry line will compensate for the volume loss introduced by a higher saturation setting. This parallel processing is delicately brought together and leveled up with the Mix blend knob, similarly with using a dedicated studio summing amplifier. The parallel tape saturation feature also transforms CompIQ Stella into a compressor/overdrive effect.

Ultimately, a 6-LED compression display indicates the amount of effect applied to the input signal, providing accurate feedback over how much the sound is processed.

Pristine audio processing

The CompIQ series of compressors is not gonna alter the magic voice of your instrument. It preserves the original guitar or bass tone while providing unobstructed, pristine audio compression. The high dynamic range of these compressors allows for natural-sounding clean tones and low noise, artifact-free audio processing, without distortions usually introduced by optical compressors.
