Becos CompIQ Mini One Pro Compressor Review

The folks at Becos in Romania are back at it again with another new compressor pedal.


This time, a more simple-to-use mini compressor for those either not needing a lot of controls or preferring less knobs to mess with. But this is no dumbed-down device. No, its a great little compressor that functions well and still includes a five LED gain reduction meter and dry/wet mix parallel compression option.



I am pretty fond of the Becos CompIQ MINI Pro Compressor reviewed earlier.


I said it "may be little, it is not short on features. The team at Becos managed to cram a whole lot of versatility into a small form factor."

While the Becos CompIQ Mini One doesn't have the same features under the hood it is the same Blackmer® VCA type compressor with FET active circuitry and WIMA audio capacitors. Basically the exact same circuit, just without so many controls.

There are three knobs and one push button on the face of the compressor. There is also an inside trimmer. More on that later.



The Ratio knob sets how much the audio signal is going to be compressed after it passes above the set threshold. It shares the same continuous range as the Mini Pro starting from 1:1 (no compression applied) to Infinite:1 (basically limiting). At 9:00 you are roughly in the space of 2:1 ratio. At noon, more like 4:1. At 3:00 things are pretty squishy at around 10:1 ratio. The full range is useable and at higher settings makes for a pretty good limiter.

The Gain knob is there to make up the gain as you increase compression. As is expected, the higher you turn the gain, the more noise is introduced to the signal. Adjusting wet dry mix (small knob adjacent to footswitch) can help mitigate added noise. It is not an overly noisy compressor, but it is definitely not as quiet as others on the market. There is plenty of gain on tap.

The Wet Dry mix dial mounted on the right side on the top of the pedal adjacent to the foot switch and allows you to blend as much or little of your clean signal with the output compressed signal. In the middle, the mix is 50/50. When set to 100% dry (all the way counter clockwise), the CompIQ Mini One Pro acts like a buffer. This is a very useful design and I really like the dial set between noon and 1:00. I'd say there is enough variability in the range to satisfy anybody.



The Sense button is a type of threshold control. It controls the level at which the compression is applied. Compression is only applied to the portion of the signal that goes above the threshold. There are two preset levels. Switched down is the Lo setting fixed at -40dBu and is suitable for very weak instrument signals. In this setting the signal kicks in immediately. The Hi setting is user controlled by a trimmer inside the pedal with a range of -40dBu to +10dBu. (See picture below showing red trimmer dial in upper left.) With the inside trimmer set to noon it is 30dBu. The Hi setting is more for higher output instruments. I much preferred how the compressor reacted and felt in the Hi setting with all 5 of my basses. But if you have a very weak passive bass, the Lo setting might be just what you need. I would personally rather have an exterior Threshold dial but for the target audience I bet most will never touch the inside trimmer. However, if you do you will be met with a lot of control. It's a trade off. Less dials on the outside, but at least you can manipulate the threshold to some degree.



There is no control of attack and release timing. The Mini One Pro offers dynamic processing of attack and release timing. This means that short transients are handled with faster timings, while steady signals get slower timings. It works well as it reacts to your playing dynamics. The timings are approximately 10-15ms for attack time and 200-220ms for release time. Attack time is the amount of time it takes before the compressor kicks in. Release is the amount of time the compressor takes to "let go", or return to normal audio level.

There are many other compressors on the market that handle attack and release this way including the Keeley Bassist. That brings up a good point. In many ways the Becos Mini One Pro has a lot in common with the Keeley. Differences include the fact that the Becos trades a Threshold dial for a push button and internal trimmer. But you also get a 5 LED gain reduction media that is far superior to the Keeley Bassist's single LED. The Becos also adds the comprehensive Dry/Wet signal dial. The Becos is also smaller. Both have an inherent transparent quality.

The Mini One Pro has a soft compression knee which means it has a subtle application of compression.



This isn't a compressor that is going to impart some sort of flavor or coloration to your tone. It is not a "tone magic" device but does a great job of subtle compression all the way to harder limiting action.

Like the previous Becos compressors I reviewed I didn't notice any loss of highs or lows. I had no issues with any of my basses and never had concern about headroom.

Did I miss the amount of controls of the Becos CompIQ Mini Pro (notably the full Threshold Knob, Soft vs. Hard Knee control, and Attack/Release timing switch)? Yes and no. For what it is, the Mini One Pro is a remarkable little tool. I personally like having more control of threshold as I use many different basses. On the other hand, I suspect the target audience is more the set-and-forget crowd. I've really come to like this one. Its simplicity is its strength.



If you are considering the Keeley Bassist, the Becos CompIQ Mini One Pro is also worthy of your consideration. The Mini One Pro is well built, looks great, and performs well. It doesn't really make your tone bigger or fatter but it does compression really well.

The footswitch is true bypass.

The pedal operates with a voltage of 9 - 12 VDC but there is no noticeable difference running at 9 volts vs. 12 volts. Using a barrel longer than 12mm will work much better with Becos compressors.


Edit: August 2020 A standard length barrel will now work fine on all new production Minis.

The retail price of the Becos Mini One Pro $156 which is priced similarly to the Becos Mini Pro at $168 which has more controls. Both are a tremendous value. Hey, sometimes simple is better.
