Whether it’s a million-dollar hook or a soul-wrenching solo, some licks are just begging for some undivided attention from the COMPRESSOR/ SUSTAINER CS400. By pumping up quieter notes and bringing down the louder ones, this little magic box packages your sound into one velvety-smooth and consistent volume. With the CS400 in your pedalboard – you’ll enjoy virtually-endless sustain and ultra-stable dynamics!

What is a Compressor?

Dynamics play an important role in music; they help to convey emotion, whether it’s a sweet and sultry blues solo – or the relentless gallop of molten metal. But uncontrolled dynamics can take all your best intentions and turn them into so much… well… mush. That’s where compression comes to the rescue – softening loud sounds, and boosting low signal levels that often get lost in the mix. So the primary function of a compressor is to make every note the same volume level. The resulting compressed signal creates a much more dense, impactful sound, with richness and room for your subtle nuances coming through – like never before.

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 Operate

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. The bright stays LED tells you when the CS400 is 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).
