The Legendary Keeley Plus Compressor The Keeley Compressor is the world's most popular boutique compressor. With over 80,000 compressors built in our workshop, we have extensive knowledge of compression, throttling and sustaining. We know what it takes to make an instrument sound like it was professionally recorded. We know how to make your guitar stand out in the mix. We know how to make it fun and easy to play. Keeley compression is how. The Keeley Compressor Plus is the first real advancement in our range of 2 and 4 knob compressors. The new features are simple and straightforward. Now there is a simple release switch that is set for single coils or humbuckers. No more wondering if the attack or version is set correctly. Your humbuckers will have all the attack and punch they should. Our team designed a beautiful tone control that emphasizes the most sensitive harmonics that can be lost during compression. The Compressor Plus now sports a blend control that retains the peaks of your playing and, more importantly, the proper phasing of your guitar signal. The Keeley Compressor Plus delivers the same frequency boost and tone sweetening that older comps gave you, now with the flexibility to easily handle any instrument. The Keeley Compressor Plus is a compressor with an expander/sustainer. Not only does it act like a regular compressor, limiting the peaks in your playing, but it adds more and more gain as the notes fade away. Now you have sustain. Nothing worse than a note or turn that died before its time. The Keeley Compressor Plus adds just the right amount of sustain and expressive bloom to your notes. The Keeley Compressor Plus's new release switch is designed to ease the transition between single-coil and humbucker guitars. Humbuckers have more average energy than single coils, which can cause compressors to stay in “compression mode” much longer. When this happens, any series of notes you play will sound dull. With the quick release of the new Compressor Plus, your humbuckers stay true and every note maintains dynamic attack and definition. The Tone Control is our own design taken from analog delays and other vintage effects. These effects used a boost circuit to recover the highs and highs after passing through the BBD or other analog delay lines. We've taken this circuit and made it a full-fledged tone control! We've found this to be the perfect way to smoothly add treble lost in the compression process. Blend Control is a way to get peaks through while having sustain at the same time. So if you want more sustain than limiting peaks, this Manhattan style of compression is for you! Keep all the peaks and transients with the blend and tone controls while adding sustain at the back. Heaven! This compressor isn't just for funk or chicken pickin' anymore. The new Compressor Plus is aimed at players who want a gentle, subtle wash of their guitar. Remove just the right amount of peaks for an ambient layer, then mix in the right amount of treble for a nice shimmer to your guitar. Use it with your favorite fuzz to create a wall of tone like you've only heard on records. Looping has never been easier than with this compressor. Consider it an essential tool when creating loops that sound well balanced. Forget everything and use Compressor Plus to get the best amp boost you've ever heard. Nothing pushes an amp like the Keeley Compressor Plus. The new Keeley Compressor Plus is the result of our specialization in compressors for over 15 years. Chief engineer and founder Robert Keeley said: “Compression was the first effect I found was difficult to produce good sound commercially, so I set out to create the best possible sound compression effect.” We have it down to a science but still treat it like art. Since it's at the heart of what we do, we can offer it at an incredible price now. The Keeley Compressor Plus is entirely made in the USA. Come to our store and watch the magic happen. We didn't just start making compressors to look good alongside co-branded coffee mugs, shirts and hats. We worked with and listened to the pros who have had the stock compressor on their boards for 10-15 years and found out what it would take to keep it on their boards for another 10, 20 or 30 years…. Add the Compressor Plus to your rig, you and your guitar will be singing for days.
