About This Listing


Sound is always subjective, but I find this unit one of my favorites. A nice clear compression is produced with minimal hiss or back ground noise with good hang time on the sustain. Great little unit for the price!

Biyang is back with a great new lineup called the "BABY BOOMS".

Smaller casings than their other lines and packs a powerful punch.

This new Baby Boom series are simply great for pedal boards as they are both space saving and powerful.

These guys have been generating an industry buzz worldwide with their full line of sound reinforcement equipment all the way from full blown stage gear to awesome tube amps, wireless guitar systems and down to this new compact effect series.Versatile, effective, well built and very affordable. (and they look great too!) A great sounding Compressor which colors the sound nicely, has many tweaking options and can certainly compete with more well known (and much more expensive) vintage rivals. Biyang is back with a great new lineup called the "BABY BOOMS". Smaller casings than their Tonefancier line and pack a powerful punch. This new Baby Boom series are great for pedal boards as they are both space saving and powerful. Measuring 2 1/4" across and 4 1/2 " tall, these will fit nicely on any pedal board offering more tone with much less space. These baby's will wail....

Here are player reviews on the Biyang CO-10 Compressor:

5.0 out of 5 stars

The Biyang Compress X-Co10 Compressor bring back quality at an affordable price !!

"This is a cross between the old dynacomp, and without a doubt the old ROSS Compressor , yes the Ross Compressor !!For those of you who don't know about the Ross , let me enlighten you . The Ross is not only Legend but it is the Compressor that really set the mark for all others among players . The Biyang Compress X-Co10 Compressor cover all of that Hand's Down! Sound wise it's there, build wise It's there !!! This pedal is truly a find , it's quiet, does not color your sound and is a real plus to any pedal board . Price wise you can't beat this You know we all try to set a mark on effects pedals by price ! Well maybe it's time we went back to where experimenting with new and lesser known brands. Jight just take our expectation's back to where they belong and the Biyang Compress X-CO10 Compressor does just that. "

5.0 out of 5 stars As good as Keeley without the hiss!!!

This pedal absolutely blows my mind. I can honestly say that I did not get my hopes up when ordering this 45 dollar compressor...I figured for the price even if it wasn't high quality it had to be better than my Boss! WOW! Literally as transparent as the Keeley I tried without the annoying hiss!!! Even with the sensitivity all the way hiss! It's an unbelievable steal for the price, and you will be doing yourself a favor to invest in one of these! Don't believe me though, try one for yourself! How can you go wrong at the price point?!

"I had one of those old DOD bass compressors back in the day, and wanted something similar without paying one or two bills for a brand-name, and found that the original FX82s are fetching even more for that on auction sites because they're "vintage" now. This unit is pretty decent, a nice warm tone that doesn't sound as sterile as the old one I had. It's only got two knobs, level and sensitivity, so there's not much fidgeting you can do with the effect, but it works well for me. Solid construction with a metal case is a plus, even if it has the color scheme of some japanimation robot. The only minus I have is the way the battery fits in - there's a raised thumb screw on the bottom of the case, which wasn't conducive to velcroing this to a pedal board. I had to take out the screw and tape shut the battery door so it was flat and level. Other than that, great effect. "

5.0 out of 5 stars I like this pedal,

This is a very good compressor, and not just "for the money". Over the years I've owned several well known "boutique" compressors and I like this one as much, if not better than those. It adds sustain and punch without significantly altering your basic tone.
