61% recommend · 13% neutral · 26% don't
Owners praise
  • Blend knob keeps pick dynamics intact while still compressing, and makes subtle settings easy
  • Single-coil/humbucker switch handles guitar swaps without re-dialing anything
  • 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”

“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.”
