All user reviews for the Biyang CO-8 Compress

Analog mono compressor for guitar and bass pedal format beefy kind. True bypass. Powered by a 9V battery or power supply Boss type PSA.
No manual, no technical feature on the site. Get by with your ears, seems to say Mr Biyang.

UTILIZATION

No record, but we are in the basic: one in, one out. Volume and effect level. The setting ranges are properly calibrated to make precise adjustments but varied.
Nothing to do with the sound but the LED that indicates the start of the effect is dazzling green. I put a nice duct tape on it to mitigate.
May be missing a setting time of attack to be more complete.

SOUND QUALITY

So there, it can not be ignored because it is not absolutely clear. In terms of compression is fairly standard with a dynamic not very high, but well suited to the guitar. You can have a small pump like Boss CS3 pushing the sensitivity. On a bass, it just eats the attack. Noise insignificant.
on the other hand, at the return of frequencies, it is as if we had an Aphex. Here adds bass and treble to magnify the sound like an exciting. It's very flattering in its clear, and it grows beautifully crunches and saturations. I love it.
With a bass, it can take place in a beautiful setting power trio or solo. Arrangements on a bit rich, it is best not to turn pain into the mix slurry.
Oddly, on electro, it manages to be one of his old saw anemic.
With a setting of attack, I put 10.

OVERALL OPINION

My purchase was motivated by the price (50 €) and the patter of the salesman. I thought it exaggerated, but at this price, why not. A test in the store, I've found a certain charm, but once at home and plugged into my stuff, I fell in love. The seller had said so true! Since then, I came back to say thank you.
Try it before because not transparent at all, I understand that it will not suit everyone. For me, its particularity is a component of my sound.
Unbeatable value for money if reliability is the rendezvous. I would redo this choice without hesitation.
In fact, they are found at Rockline in Toulouse. I recommend the shop.
