Here's what Behringer says about the CS400 Compressor/Sustainer Pedal:

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 9V battery or our PSU-SB DC power supply (not included).

Sound Value

Push the good stuff to center stage with the Compressor/Sustainer CS400. This pedal smoothes out volume peaks and provides endless sustain with ultra-stable dynamics via the dedicated Sustain, Level and Attack time controls – for the ultimate in sound shaping.

Boost

A boost pedal does one simple thing brilliantly — it makes your signal louder, stronger, and more alive. Whether you’re pushing a valve amp into natural breakup, lifting a solo above the band, or adding a touch more presence to your core tone, a clean boost gives you extra headroom without changing your character.

Use it at the front of your chain to drive other pedals harder, or after your gain stages to raise volume without adding distortion. Subtle or powerful, transparent or slightly coloured, a boost is one of the most useful tools on any pedalboard — small box, big difference.

Compressor

A compressor pedal evens out your dynamics, smoothing peaks and lifting quieter notes so everything feels tighter and more controlled. It adds sustain, clarity, and balance — making clean chords ring longer, country licks snap with precision, and funk rhythms pop with consistency. Subtle or pronounced, compression shapes the feel of your playing as much as the sound.

Use it at the front of your chain to tighten your core tone, add sustain to leads, or keep complex passages sitting neatly in the mix. From gentle polish to unmistakable squash, a compressor is one of those foundational tools that quietly makes everything sound more professional and dialled in.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

used

Used pedals bring character, value, and often a bit of history to your board. Whether it’s a well-loved classic or a recent release looking for its next home, a used pedal offers the same core tone at a more accessible price. Fully tested and described clearly, it’s a chance to grab great gear without paying brand-new money.

Go used to explore different sounds, track down discontinued favourites, or build your setup more affordably. Sometimes a pedal with a few marks on the casing still delivers flawless tone — and might even have a story or two behind it.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
