Add amazing impact to your tone and provide endless sustain.

The Behringer CS400 compressor/sustainer pedal lets you take total control over your dynamics. With dedicated knobs for attack, sustain, tone and output level, you can smooth out your playing and add expressive sustain. The CS400 helps you tame harsh, loud notes and give a boost to low signals, keeping your overall volume consistent. It's great for leveling out your guitar and bass strings, making each note ring out evenly. Slap bass players will love how the CS400 makes thumb slaps, pops and muted notes all the same volume for an ultra-percussive attack.

Dial In Your Ideal Compression Settings

An intuitive interface makes it easy to shape your tone with the CS400. The Attack and Sustain knobs let you determine how aggressively the compressor clamps down. More sustain accentuates ringing notes, while a faster attack tames transients instantly. The Tone knob cuts or boosts treble frequencies so you can tune your squashed signal. A Level control allows you to compensate for volume loss or give your sound an expressive boost. Whether you need light, transparent compression or an extreme, pumping squash, the CS400 puts complete control of your dynamics at your feet.

Quality Switching and Power Options

The CS400 features a top-notch footswitch that maintains your tone integrity when disengaged. Status LEDs let you know when compression is active. Power up the pedal with a 9V battery or Behringer's PSU-SB power supply (sold separately). Give your playing dynamics a makeover and sustain for days with the Behringer CS400 compressor.
