As most of you know compression is close to my heart. My go to, number one, all time most used pedal, is the Boss CS-2. The Boss CS-2 is old faithful. Some time ago I sat down with producer/engineer Robert C to really dissect what it is the Boss CS-2 does that makes me love it so much. Turns out, the CS-2 adds some distortion and top end which pops those harmonics. Most importantly, compression gives me more articulation, and that's one of the most integral parts of my playing.
Robert and I go in depth, we A/B his Compressor Pro, and the compression stage of the Tone Workstation. He explains why each do what they do, and why one might add "color" to your tone while the other doesn't.
