The Boss CS-3 Compression Sustainer is a versatile compressor pedal designed to provide smooth dynamic control, enhanced sustain, and a more balanced overall guitar signal. Since its introduction in the mid-1980s, the CS-3 has become one of the most widely used compression pedals for electric guitar, suitable for clean tones, country picking, funk rhythms, and singing lead lines.
The pedal features dedicated controls for Level, Tone, Attack, and Sustain, allowing players to fine-tune both the response and character of the compression effect. From subtle evening-out of picking dynamics to heavily sustained lead tones, the CS-3 offers a broad range of usable settings for many different musical styles.
Unlike simpler compressor designs, the inclusion of a Tone control makes it possible to compensate for high-frequency loss or shape the overall brightness of the compressed signal. The CS-3 can be used as an always-on tone-enhancing tool, a sustain booster for solos, or a dynamic control device for clean and rhythm playing.
Its rugged Boss compact pedal construction and straightforward operation have made the CS-3 a long-standing pedalboard staple for guitarists seeking reliable compression and sustain.
