  • Low-noise design for super-quiet operation

Sustain Without Distortion

The Boss CS-3 Compression Sustainer pedal manages to give you singing sustain without distortion by continuously lowering the level of loud signals while boosting quiet signals.

This gives you an even, “compressed” signal with a consistent volume as the note decays.

With this clean sustain and its strong sound, you can perform some beautiful, mellow guitar solos and cut through the mix in even the densest ensembles.

Shape Your Sound

Four knobs and footswitch give you great control over your sound

You can easily set the output volume with the level knob and speed at which the effect is applied with the attack knob.

A sustain knob is also present, allowing you to choose precisely how long the sustain on your notes lasts.

Another extremely useful control is the tone knob which allows you to add in treble so you can compensate for any loss of high end that the compression may cause, so you get great sound no matter what.

Great Tone with Singing Sustain

Using the Boss CS-3 Compression Sustainer, you can achieve a broad range of great sounds. From incredibly clean solos and arpeggios to funky, percussive playing with a cutting sound – the CS-3 does it all.
