This results in a smooth sustain without compromising on the original sound quality, meaning your guitar or bass will still sound at its best. The CS-3's compact, sturdy construction means it can survive in the toughest of gigging situations, and fits nicely in most pedal boards. The CS-3 features on-board Level, Tone, Attack, and Sustain controls for tonal shaping. The high quality circuitry and low-noise design for discreet operation make this pedal ideal for compression loving guitarists and bassists.
