BEHRINGER COMPRESSOR/SUSTAINER CS400 Ultimate Dynamics Effects Pedal If tone is the name of your game, the COMPRESSOR/SUSTAINER CS400 will add amazing impact to your tone and provide endless sustain. What's a Compressor? Dynamics play an important role in music. They help to convey emotion, whether it's a sultry blues solo or the unrelenting gallop of unfettered metal. But uncontrolled dynamics can take all your best intentions and turn them into so much, well...mush. That's where compression comes in, softening loud sounds and boosting low signal levels to keep everything more uniform. So, a compressor's main job is to make every note the same volume. Balancing Act Ever notice how some strings on your guitar or bass sound louder than others? This is partly due to physics. Strings with lower mass just don't put out as much volume as the heavier ones. When used properly, a compressor makes all of the strings the same volume. Compressors are also great for slap-style bass players, making thumb slaps, string pulls and muted notes all the same volume, for an extremely percussive effect. Easy to Use You can dial in the right amount of compression using the dedicated ATTACK and SUSTAIN dials. The LEVEL control allows you to set the output to subtle, or engage a monster volume boost. TONE lets you add exactly the right level of highs. From clean, snappy country leads to rock solos that scream for eons, the CS400 is built to make your sound the center of attention. Its LED tells you when it's on, and the top-quality on/off switch maintains outstanding signal integrity in bypass mode. You can power this scene-stealer with either a 9 V battery or our PSU-SB DC power supply (not included). Value The COMPRESSOR/SUSTAINER CS400 is an affordable way to add some serious finesse to your playing. Check one out at your BEHRINGER dealer and let your playing take center stage.
