Compression is great in the studio as a way to control or modify the dynamics of a signal. Guitarists have found compression to be a perfect addition to their pedalboards, giving them big sustain for solos, as well just simply controlling playing dynamics - not to mention being essential equipment for chicken-pickin"! BOSS"s CS-3 compression/sustain pedal does all of this and more while keeping your signal integrity intact. The CS-3 is a great tool for bassists, too, making sure the low E sounds as loud and clear as the high G. You get onboard control over Level, Tone (EQ), Attack, and Sustain for precise sound shaping. The CS-3 is a top-notch compressor at the perfect price.
