Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Keeley Compressor Pro.

Features and functionality

  • The Keeley Compressor Pro's design allows it to be used effectively before or after overdrive pedals to manage dynamics and maintain tonal clarity.

    Source
  • The Keeley Compressor Pro is noted to overly compress guitar signals, leading to a loss of dynamics, which can be problematic in live settings.

    Source
  • The Keeley Compressor Pro includes an auto mode for attack/release, useful for an always-on starting point, but manual adjustments may be needed for transient control.

    Source
  • The Keeley Compressor Pro can be used to "slam" the input of an amp by cranking the gain past unity, enhancing clarity and dynamics.

    Source
  • A gain reduction meter is highly desired by users for easier visual monitoring of compression levels.

    Source

Use cases and applications

  • Known for producing a "country" sound, the Keeley Compressor Pro is less favored for genres requiring subtle, transparent compression.

    Source
  • Users find the Keeley Compressor Pro effective for both clean and distortion tones, smoothing out overdriven chords and leveling signals for rhythm guitar.

    Source
  • Positioned right after the Euna and Tuner, it enhances clarity and sweetens the tone, especially effective when used as a pre-dirt sweetener.

    Source

User experience

  • Some owners note a persistent whine when using the Keeley Compressor Pro, which may be attributed to non-isolated power supplies.

    Source
  • Users report a significant volume boost when engaging the Keeley Compressor Pro, especially noticeable when used incorrectly in the signal chain.

    Source
  • Some users initially find the pedal complex but recommend adjusting settings based on personal sound preferences rather than generalized advice.

    Source

Comparisons

  • The Wampler Ego is highlighted as a superior alternative for maintaining low end in drop tunings, preferred over the Keeley for its tonal balance.

    Source
  • The Strymon Compadre is favored for its dual functionality, offering both studio and classic pedal compression, appealing to those seeking versatility in sound shaping.

    Source
  • The Keeley Compressor Pro is likened to an IC compressor, offering a squashed and snappy sound ideal for single coil pickups, whereas the optical Diamond Comp lifts tones, better for humbuckers.

    Source
  • The Keeley Compressor Pro is described as a limiting style compressor, suitable for maintaining a clean, silent compression without altering tone significantly, unlike the more tonal Diamond Comp.

    Source
  • Consideration is given to switching to the Cali 76 Compact for potentially different tonal characteristics.

    Source

Mods and upgrades

  • Lollar P90 pickups are recommended for those experiencing a muddy tone with stock Gibson P90s, providing a clearer, more defined sound.

    Source

Setup and maintenance

  • Users suggest setting the threshold control so the LED indicator engages on every pick attack, even with lighter touches, for consistent compression.

Not Impressed

I was really excited about getting this compressor, but the build quality was bad. @ $299, it would have been the most expensive pedal I've ever bought. So bad, I ended up sending it back which was a serious downer. Sound wise, the Keeley was good out of the gate, but I was also getting a lot of clipping and stutter so really not happy with audio quality either. All said and done, I could kick myself for not following my original inclination with an Xotic SP. Keeley's sexy newness, simply failed in its promise. ~m

not so pro, huh?

raucusbacchus

Pro-no. Fired her before she even got warmed up. I tell you what, I don't get the box opening fad, but I bet the look on my face would have certainly drawn a laugh from the sadist crowd when I saw the state of things. I'll just have to keep shopping. ~m
