This pedal is in very good condition with no damage or noticeable wear. It has been fully tested and is working well. It does not come with the original box. From Behringer If tone is the name of your game, the COMPRESSOR/SUSTAINER CS400 will add amazing impact to your tone and provide endless sustain.What is 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.Easy to OperateYou 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).Features:Get super-smooth compression and endless sustainThis BEHRINGER product has been designed to compete head to head with leading products on the marketCompress loud and boost low signals without degrading the original soundDedicated Level, Tone, Attack and Sustain controls for awesome sound shapingBlue status LED for effect on/off and battery checkRuns on a 9 V battery or the BEHRINGER PSU-SB DC power supply (not included)First-class, electronic On/Off switch for highest signal integrity in bypass modeHigh-quality components and exceptionally rugged construction ensure long life
