“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”
“I've found that I hear the effects of the compressor most when I'm using in conjunction with the overdrive from the Archer, although it does happen to make a quite noisy buzzing sound when I use it with single coils.”
“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.”
“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.”
“I have had the compressor plus. It is a solid compressor but the IQ also has a 6 band eq wich makes it incredible for tone shaping.”
“I have a Keeley plus & a Walrus Mira. The Keeley is noisy and squishy, it's possible to dial it in more subtly, but I get more use out of it as a boost/sustain enhancement.”
“I have the Keeley, I like how it sounds but I really miss an Attack knob. I won’t be getting a compressor without one again”
“I had the big box versions of both and went with the Keeley. It had a lower noise floor and could cop the MXR settings as well as do it’s own thing.”
“My point was that my $18 one performs as well as the $120 one (even with its blend function), and doesn't introduce/amplify the existing noise nearly as much.”
“I did own a keeley comp+ about 5 years ago or so. It was definitely noisy compared to other ross types I’ve used - wampler and analogman. Especially when turning up the sustain and having the clean blend low”
“I admit KC+ was pretty bright. I never thought it got too ice-picky, but you can roll some of that off with the tone knob.”
“Mine is noisy as well. It's an excellent compressor though, so I got over it lol just have to be more careful when playing clean”
“Personally I have this pedal and like playing with it, but I also don’t totally miss it when it’s off if that makes sense.”
“Mine was so noisy I contacted the company and they paid for it to be sent to the US from the UK and returned it to me quickly - just as noisy!”
“HRK to me is made for country blue grass and that kind of stuff but Keeley is a versatile comp that doesn't color ur tone”
“The empress was good (as was the Keeley) but they did not give me this amazing full of body sound that the Cali76 does.”
“I think the Keely is just a better pedal. The blend knob is very useful and it is a smoother compression, which I like.”
“I agree on the Keeley; I had one and found it to be very disappointing. It tries to do two things and ends up not doing either very well.”
“I really liked my Keeley Compressor Plus when I had my Supro Delta King 12, and when I played my Monoprice Stage Right 5w. It was always on. Unfortunately, with my Marshall DSL1 and Orange Rocker 15 it sounded like ass and I traded it a few weeks ago.”
“I have only played the Keeley Compressor Plus, not the HRK, but I can tell you that you will not be disappointed. It’s one of those effects that you didn’t realize that you needed until you turn it on. It’s now one of my favorite pedals I own.”
“Yeah, the highs are definitely enhanced by the Tone knob on the Keeley, but even with it at 0, there is still pronounced broadband noise”
“First, the Keeley seems to be most of the special sauce I was looking for. I find myself playing clean way more now.”
“I had this for a long time but I wanted something a little less noisy so I sold it and got the origin effects comp.”
“I had this pedal for a few years and really liked it. However, I didn't like the Attack switch.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“Try turning down the blend Knob with the compressor, i rarely put mine past 9 o'clock, same with sustain. Edit: English is hard”
“It's a parameter preset for the attack and decay depending on whether you play single coils or humbuckers”
“The Keeley 4 knob is the way to go. The pickup selector and the blend knob make it the better choice.”
“"all it does is add way more noise" That's because you aren't powering the pedals properly most likely and the compressor is lifting the noise up. If you use onespots/or plug wall warts into the wall with no type of power conditioning/isolation you will get noise.”
“Tubescreamer>comp+ is my favorite combo out there. I know the blues driver is a bit different, but same general idea. You want the comp level at unity or boost with the overdrive, I do high sustain and blend, tone to taste, not unlike what you’ve got, just probably more volume.”
“So it does depend a bit on your set up but if you’re like me and use both single coil and humbuckers into a very clean amp, this is how I’ve been doing it. I keep going back and changing it daily it seems but I like both mini switches set to the right and volume at unison or maybe a slight boost.”
