Fluid Operation

Compression evens out volume by reducing loud signals while boosting soft ones, and the CS-3s Attack knob determines how quickly the circuit reacts. Turning it clockwise preserves string attack for a snappier, more percussive sound, while counterclockwise settings provide progressive control over signal spikes. Twisting the Sustain knob increases the amount of compression, allowing you to tighten the sound and produce natural sustain without distortion.

Precision Dynamics Control

The CS-3 features a high-performance VCA circuit that delivers stable, consistent compression with very low noise. Renowned for its distinctive character and well-balanced response, the pedal maintains clarity across all playing styles. It excels at everything from hot country licks and punchy power chords to singing solos, making it an essential tone-enhancing tool.

Tonal Versatility

The Tone knob adds another layer of versatility by shaping the EQ of the compressed signal. Higher settings enhance the treble for a sharper, more cutting toneperfect for chimey arpeggios, funk rhythms, and parts that need to stand out. Rolling it back softens the highs, creating a warm, mellow voice that suits genres like jazz and neo soul. Whether you need some extra bite or a smoother feel, the CS-3 helps you sculpt your sound to match the music youre playing.
