I was looking for an always-on comp to add some mojo to my DI guitar sound. This pedal did add a nice dimension to the tone, but not quite what I was looking for. Also, in my setup, it did add some squeal to overdrive presets.

It's a nice compressor, simple and not overpowering, very clean, nice small size. Worth the money all day

Sounds great, very easy to use, but IMHO too noisy for a lot of applications.

I bought this pedal to serve double duty as not only a compressor, but as a buffer amp for my POD Go... This unit excels at this job... I also own a PRS Mary Cries Optical Compressor pedal, but it was too large to fit on the POD Go's pedal board (Temple Audio Solo 18)... So the compressor had big shoes to fill concerning audio quality and it did not dissapoint... I was using a Peterson Mini Strobo Stomp Pedal as a buffer, but it definately works better with the Keely compressor which not only sounds (and feels) better than any of the digital compressor models in the POD Go, but it frees up a slot for some other effect...

It's quiet, and does what it's supposed to do. A beautiful sounding compressor!

Get this if you want a full range of classic well-engineered compression options without any fuss. For my purposes, this comp is quick, easy and sounds great across the ranges with just a twist of two knobs, instead of having to compensate between 3-5 different knobs to get those same sounds.

Don't get it if you
a. want something transparent (the guitar limiting amp is great for that, I have it as well) or
b. you want to fiddle with extreme setting for experimental / niche effects, or
c. you're a control freak and want to dial in everything manually.
d. want to understand the principles and elements of compression (threshold, ratio, attack, release, knee, mix)

If one of those scenarios describes you, that's legit. But that doesn't make this a bad compressor. It just makes it not the right compressor for YOU. This is a compressor for the rest of us who just want "one of those sounds" across the sweep of the knob in very quick and easy manner.

Great addition to a mini rig, especially if wanting black pedals. I tend to use just a tiny bit of compression to control the low end and this pedal does the job for me.

Keeley products always shine. This is no exception.

Having used the Keeley Compressor Plus for a while now, I expected this mini version to sound as good. It does not. And since there's no way to set anything except a "comp" knob, and who knows what THAT'S doing...it's pretty useless to me. Now, MAYBE you have the right guitar to make this thing sound good, but it sure does nothing for my rig. I hope you have better luck than me... I'm sticking with the Compressor Plus.

This is a great transparent mini pedal, simple to use and gives great feel. I have used the Xotic Compressor for years on my boards and this one blows it away. The stock settings they show for a low, medium and bloom settings work perfectly. So easy right out of the box, took it to a gig that night.

I was not interested at a two knob comp. I have owned several other comps (4 and 5 knob) and have never been completely happy or able to use the comp in certain situations. I certainly didn't think less features was the direction to go but… I watched the many demos and Andy sold me on this. I was not disappointed. The thing works with singles and humbuckers. I can't seem to get a bad sound out of it. Even at high settings it is amazing. I set it higher than I usually use a comp because it doesn't kill my tone. This is the the happiest I have ever been with a comp and finally have one that will remain on my board. Thank you RK!
