The keeley compressor plus pedal builds on the most popular boutique compressor in the world. Keeley have developed an unrivalled array of knowledge when it comes to dynamic processing and they know exactly what to do to transform your guitar tone. The compressor plus features a simple release switch that is tuned for single coils or humbuckers. You can flick the switch to get the perfect release setting depending on the pickups you are using. This intuitive control design varies on throughout the pedal with an easy to use tone control that is designed to emphasise the most sensitive harmonics that can often be lost in compression. The pedal is also equipped with a blend control to retain the peaks in your playing and maintain the proper phasing of your instrument. The compressor plus is expertly designed and crafted to deliver the same hypnotic range of frequencies and rich sweet tone that keeleys original compressors gave you and is perfectly suited to any instrument.
