Keeley 4 Knob Compressor Review

Summary

  • Pros: All of the benefits of the two-knob version with the added ability to easily alter the “Attack” and “Clipping.” It sounds great and is easy to get to grips with.
  • Cons: Some noise using high sustains, and a little expensive.
  • Overall: A fantastic compressor, well worth the extra expense for players using more than one instrument or setup.

The two-knob Keeley Compressor offers fantastic sound quality in a compact, straightforward package. It’s a hand-built legend of stompbox compressors, but it isn’t perfect. The main issue is that two of the controls – “Attack” and “Clipping” – were hidden away within the body of the unit, meaning that while they could be adjusted, it wasn’t exactly ideal for controlling a wide range of parameters. Although the simpler version gets the basic job done, for players with more than one guitar it could only really be sonically optimized for one of them – unless you opened it up the box to adjust the internal “Clipping” control – and you pretty much had to choose an “Attack” setting you like and stick with it until you did the same. So does the 4 Knob Keeley Compressor win out, or are you better off trying to pick up the bare-bones two-knob version for a little cheaper?

The four-knob Keeley Compressor has the basic same aesthetic appeal of the two-knob version, but with the extra two knobs up top, the full labels (rather than just the first letter) on each and little scales arcing around the side of them, it does look a little more polished and generally cooler. In terms of quality, however, you’re getting exactly the same thing, and the resulting tone is just as true to your original signal – likely thanks to all the care that goes into selecting the best components.

You do get a small amount of noise, but this can be minimized by adjusting the “Sustain” or “Clipping” controls accordingly, with the “Clipping” option being particularly important if you’re using humbuckers with a high output (enabling you to prevent distortion). The fact you can do this (and slow down the attack) on the four-knob version without opening the pedal and taking a flat-head screwdriver to the relevant internal pots is the core benefit of the 4 Knob Keeley Compressor, great for anybody with more than one setup or instrument.

The only downside is the extra cost, but if easier access to the two additional controls is important, the still-excellent sound quality and it’s extra flexibility make the 4 Knob Keeley hard to really dislike.
