Not Impressed
I was really excited about getting this compressor, but the build quality was bad. @ $299, it would have been the most expensive pedal I've ever bought. So bad, I ended up sending it back which was a serious downer. Sound wise, the Keeley was good out of the gate, but I was also getting a lot of clipping and stutter so really not happy with audio quality either. All said and done, I could kick myself for not following my original inclination with an Xotic SP. Keeley's sexy newness, simply failed in its promise. ~m

Pro-no. Fired her before she even got warmed up. I tell you what, I don't get the box opening fad, but I bet the look on my face would have certainly drawn a laugh from the sadist crowd when I saw the state of things. I'll just have to keep shopping. ~m

"The Comp Pro holds a sincerely large part of the equity of the tone that I hear in my head. I don’t see any board in my near future not having one. The Compressor plus is similar in essence, just more compact, yet still as effective! These two pedals will indeed prove that any style, taste, genre that applies to the guitar; the sound and tonal aid offered from these pedals can apply to all. I love them."
"My pedal board is getting a little work done at @goodwoodaudio, this is totally chaos but it's kinda fun!" - the Keeley Compressor Pro can be seen in the photo.
“When I firstnstarted getting into boutique and modded pedals, Keeley was one of the first company that my attention was drawn to. [...] The Compressor Pro has become indispensable for me in the studio, it’s so versatile and transparent.”
