61%of 69 owners recommend
61% recommend · 13% neutral · 26% don't
Owners praise
  • Blend knob keeps pick dynamics intact while still compressing, and makes subtle settings easy

  • Smooth, largely uncolored compression that owners leave always-on
Owners complain about
  • Audible hiss and broadband noise, by far the most common owner complaint

What Keeley Compressor Plus owners say

“The Keeley compressor has been on my board for a long time and it works well for me. I switch guitars between a tele and a es-135, so the simple single coil/humbucker toggle switch is a very useful feature.”
— Sensitive-Muscle2606 on Reddit
“I'll say the only reason I left the Keeley for the Wampler was because the Wampler comes in mini... Both are great. Love the pickup switch on the Keeley too”
— chancesteward on Reddit
“My compressor Plus buzzes like crazy with my single coil guitar and it drives me nuts. I find if you turn down the sustain knob it helps, but having extra sustain is kinda the point.”
