Boss CS-3 Compression Sustainer — Classic Analog Dynamics

The Boss CS-3 Compression Sustainer has been a pedalboard staple since 1986, trusted by countless guitarists for natural compression and rich sustain. It evens out dynamics by reducing loud signals while boosting soft ones, delivering smoother tone without distortion. The CS-3 is the right choice for guitarists and bassists who need a low-noise compressor that handles both subtle dynamic control and aggressive lead sustain.

What Sets the CS-3 Apart

A high-performance VCA circuit paired with a dedicated tone-shaping stage sets the CS-3 apart from most stompbox compressors. This VCA delivers stable, consistent compression with very low noise. The Tone knob lets players shape the high-frequency response of the compressed signal — push it up for cutting funk arpeggios or roll it back for warm, jazz-friendly mellowness.

Four-Knob Control Layout

Four dedicated knobs give direct access to every compression variable, with Level compensating for compression-induced volume loss.

• Sustain: compression ratio — sets amount of compression, from gentle leveling to squeezed sustain
• Attack: response time — clockwise preserves string attack for snap; counterclockwise smooths spikes
• Tone: high-frequency EQ — adds treble bite or softens highs for warm voice

Signal Path and Electrical Specs

Professional-grade electrical parameters ensure clean integration with guitars, basses, and downstream gear.

• Nominal Input/Output Level: -20 dBu — handles passive and active pickups with headroom
• Input/Output Impedance: 1 M ohm input, 1 k ohm output — preserves high-frequency detail and drives long cable runs
• Bypass: Buffered — keeps tone consistent when the pedal is switched off

Power, Connectors, and Build

The CS-3 uses the classic BOSS compact stompbox chassis, fitting any standard pedalboard.

• Inputs/Outputs: 6.3 mm TS jacks — standard instrument connections for guitar and bass
• Power: 9V battery or PSA-series AC adaptor, 20 mA draw — efficient for daisy-chained pedalboard power
• Dimensions and Weight: 73 x 129 x 59 mm, 380 g — classic BOSS compact footprint with solid, road-ready build
