    • Beyond excellent!
Style: Pedal
Incredible performance and sound. No tone colouring is perceived, despite how flexible it is. It's a safe option for any type of rig/sound.

    • Good compressor, easy to dial in good tone.
Style: Pedal
It was excellent. I mistakenly thought it was defective then later discovered the power brick on my pedalboard was defective and was the source of the problem. This pedal was extremely easy to use and had an excellent compression effect, easier to dial in than the MXR pedal that I bought to replace it. ... show more

    • Covers the full range of "subtle" to "squished" compression
Style: Pedal
Keeley's compressor pedals have been an industry favorite for many years, and the Compressor Plus is a compact and relatively affordable example of why. Keeley certainly didn't "invent" the compressor, and I've used pedals like the BOSS CS-3, MXR Dyna Comp, and Ross Compressor that have done the job well for several decades. However, this particular pedal from Keeley merges the best attributes of all of those pedals into a single, easy-to-use box. I find that the BLEND control is a important addition that you see in more and more compressors nowadays. (Wampler's excellent Ego Compressor also features this control). Basically, it's a "mix" control so that you blend in and amount of dry signal along with the compressed signal. This is important because in many cases, you want the note sustain and volume limiting qualities of a compressor, but don't want to lose that initial "punch" of the note. The BLEND knob allows you to adjust for both, and there's a toggle switch that further adjusts for the difference in attack between single-coil and humbucker pickups. (Coincidentally, my Reverend guitar features P-90's and I found that those worked better on the humbucker setting, despite them being technically a variant of a single coil pickup). The Compressor Plus is capable of adding tons of rich sustain, similar to that first time I plugged into a BOSS CS-3 and was amazed that an electric guitar could sound like that! It also can do the "chicken picking", "squished" type of compression prevalent in country or other music with quick, clean note passes. Thanks to the interplay between BLEND, LEVEL, and SUSTAIN, it's possible to also make it quite transparent for a more subtle effect. A few notes/caveats... The TONE knob works well, but it is not really meant to be an "EQ shaper" for your overall tone. It is more subtle than that, and basically just enhances or subdues the upper end dynamics through compression. Also, this pedal (as with many compressors) is susceptible to noise issues if you have problems with your power supply. I initially plugged it in with a separate power supply than my pedalboard. I must have been getting some type of ground loop or something because it resulted in terrible noise to the point of being virtually unusable. However, when I attached it to my board and used the same isolated power supply as the other pedals (Voodoo Labs Pedal Power Mini x4), the noise was almost completely gone. Just something to be aware of if you encounter that issue. ... show more

    • Great compressor!
Style: Pedal
Do the research and try different types of compressors until you find your own sound. This is the one I bought and have no regrets. Great sound and very easy to dial it in. Just an FYI, I use this is in front of the distortion pedals (Rat V2, BD-2 etc).

    • Keely has it all!
Style: Pedal
This is a good compressor, that's it. It does what it says it can do. The plus is for the blending knob I guess, that's one of the few things you don't get on most compressors. I put it right at the front of the chain and it gives me the EQ and slight boost I need. I play classic hard rock in my current band and it tightens up the sound and adds a bit of bottom end so I use the tone to equalize that. It is a solid, well built product and fits great on my board. Great price too. Thank you Robert Keeley! ... show more

    • Compressor? This is the best booster I have ever tried!!!
Style: Pedal
I bought this compressor to add some color to my tone. When I received it... I plugged my Fender Strat (HSS) into the Keeley Compressor plus and plugged it straight into a Marshall Origins 50 tube amp. Holy sheet!!! This is the tone I was looking for!!!! Not so much compressed as overdriven! I have every major overdrive pedal you can imagine, BOSS Waza Blues Driver... BOSS non-waza BD, several green Ibanez pedals, ... always looking for that blues sound (think 80's Clapton beer commercial or SRV Texas Strat blues sound.) This thing is incredible. To make it a great upfront clean OD compression pedal, just bring the sustain and level up over the 1 o'clock position and crank up your tube amp. Fabulous pedal. Won't play without it. I leave it on the humbucker setting even through single coil pickups and just tweak sustain and level... as a bonus... the tone knob can be used to bring down the ice-picky treble boost that happens with all my other driver pedals. Well done Keeley!!! (As always.) If you throw out all your other compressor pedals and blues drive pedals and get this one... you will be happy!!!! ... show more

    • Best Mid-Priced Compressor Pedal
Style: Pedal
Yes, you could pay double the price for a high end boutique compressor pedal, but out of all the big pedal brand's compression offerings out there, I found this one to be the most versatile and transparent. It it based on a modified vintage Ross compressor circuit. I replaced an MXR Dyna-Comp with this. The Dyna-Comp, while it has a long vintage history, is *very* noisy, and squashes and colors your tone with a very specific sound that you can't dial out. The Keeley Compressor Plus lets your natural tone shine through while still providing great dynamics control. You can also dial in that squishy squashed tone if you need to, but with way less noise! The Sustain and Blend controls allow you to dial in as pronounced or subtle an amount of compression you want, while the tone knob allows you to do any EQ compensation if needed. This is definitely the best bang for your buck in a compressor pedal, just buy it, you won't regret it! ... show more
