What we say:

BOSS’s colourful stomp boxes are the most recognisable pedal range in existence. For over 40 years, guitarists from bedrooms to stadiums have put their boot down on a BOSS effect to transform their sound. Several models have passed into guitar legend and early examples can fetch extremely high prices. Happily, BOSS have maintained their stellar reputation for world-class effects in bomb-proof casing with their current range and have fended off the imitators for decades to remain the pre-eminent single pedal effects manufacturer in the business. If there’s an effect for guitar (or bass, vocals, keys…be creative!) then you can bet BOSS have a pedal of it in their range or even invented it outright! Every guitar player should get to experience the joy of selecting a pedal from BOSS’s exhaustive roster, plugging it in and unleashing their wildest sonic dreams.

The famous Blue compressor form BOSS! If your playing needs a little smoothing out, shaping up and polishing with a little sheen, you may need a compressor in your pedal chain.

Used mainly with clean sounds of lower gain tones (high gain tones are already pretty compressed to begin with), a good compressor like the CS-3 can subtly boost quieter notes and bring down the ceiling with louder ones to give your guitar parts a little more linearity and cohesiveness. The ideal outcome of using a compressor is that you don't hear it! With a set of simple controls you should easily be able to dial in the optimal amount of squeeze for your signal.


The CS-3 Compression Sustainer pedal compresses louder signals while boosting lower signals, providing smooth sustain without degrading the original sound quality. This is the perfect pedal for guitarists and bassists who want to sound their best.
  • Compact compression/sustainer pedal with high-quality circuitry
  • Compresses loud signals and boosts softer signals for a smooth overall sound
  • Onboard Level, Tone, Attack and Sustain controls for precise tonal shaping Low-noise design for super-quiet operation

This pedal works really well. Not used a compressor before, but it improves the sound no end.

Great quality compressor which does exactly what it is supposed to. I have a few Boss pedals now and use them frequently on my board as they are simple and versatile tools which dynamically evolve my guitar sounds.

Great pedal, you dont realise how great until you turn it off. Just makes your sound.....professional. And it doesnt take away the nuances of your playing if dialled in correctly. Take time to read up on what each setting does.. and it works like a dream

James S. - 21/9/2019

Have always rated this brilliant compressor from Boss . Very versatile . Good price point and competes well with more expensive boutique compressors .

Callum M. - 22/2/2018

Does what it says on the tin. Classic Compressor / Sustain pedal. Very happy

STEVE M. - 22/2/2018

Very well made and excellent performance

PHILIP B. - 30/11/2017

As a Compressor, not very effective - the sustain becomes course when turned up beyond noon position
