Guitar Effects Canada - Keeley Compressor Pro

Keeley Compressor Pro.  The stomp-box sized compressor/limiter is hand made in Oklahoma, USA and engineered to be an indispensable tool to your musical endeavors.  It is in no way limited to be used with only guitar.  It has been designed to work as a studio compressor accepting any range of inputs and a frequency response and noise level matching the finest compressors made.

SMOOTHING – Changes in signal level happen when the singer moves away from the microphone or when a guitar player may not use perfect technique in controlling their dynamics, i.e. less than perfect picking hand technique.  To smooth changes in dynamics use the Comp Pro for low to medium compression.  Set AUTO Switch to ON.  Adjust the Compression RATIO Control to 2:1 to 4:1 for example.  Set the Gain Reduction LEDS by adjusting the THRESHOLD Control to indicate 3-9 dB of gain reduction on the 7 Segment LED Bar.  Adjust GAIN Control if needed.  Set KNEE Switch to SOFT.  Now play slow and steady chord work, list to how toggling the KNEE switch back and forth Hard/Soft affects your tone and the attack or punch of the notes as well as the release.

SUSTAIN – To add sustain to guitars or keyboards start with a higher Compression RATIO setting for example 10:1 to ∞:1,  Set THRESHOLD Control so that THRESHOLD LED turns Red for average level of your guitar or performance, the LED stays red about half the time.  You can set the KNEE Switch to HARD or SOFT, SOFT may seem more transparent.

CHICKEN PICKING COMPRESSION – Set RATIO Control to 5:1 to 10:1, a quick RELEASE Time of .5s to 1s. ATTACK Time for quick attack 10-50ms and THRESHOLD Control set to give you 9-12dB of Gain Reduction/Compression on the 7-Segment COMPRESSION LED Array.  This will typically give you compression artifacts or effects like a breathing or pumping sound.

BASS BOOM AND SLAP – For a punchy bass guitar sound set the Comp Pro for a medium to high Compression RATIO (6:1 to 10:1) and adjust the THRESHOLD so that the -12dB and sometimes -20dB COMPRESSION LEDs are lit while playing.  Set KNEE to Hard mode.  That will make the bass punchy and slap a bit harder, reducing boominess.  Try Soft KNEE for a a different feel.  Set AUTO On.

PREVENT DIGITAL DISTORTION – Set Keeley Compressor Pro as a Hard Limiter by turning RATIO control all of the way up to Infinity to One compression ratio.  Set KNEE for Hard. By adjusting the final Gain level to your clipping lights on the digital recorder, you can insure you won’t ruin recordings or get unwanted distortions.

SPEAKER PROTECT (Concerts, Churches, Sound Systems and P.A.s) – You can use the compressor as above as a Hard Limiter.  If when playing you hear distortions from your sound reinforcement equipment you can reduce the THRESHOLD, increase RATIO, and reduce GAIN to achieve perfect results.  This is where it might be nice to use your Keeley Compressor Pro as the last effect in your signal chain as it can prevent different effects from getting too loud or being added together to drastically increase output volume.

NEVER LEAVE HOME WITHOUT YOUR KEELEY COMP PRO – The Compressor Pro makes the perfect booster or driver for your rig!  You can always set the RATIO control for 1:1 compression (otherwise known as No Compression) and use the GAIN to push your amp, pedals, speakers, or other guy out of the way!  Once you have learned your new Comp Pro there will never be a reason not to use it.
