Boss CS-3 Compression Sustainer
The CS-3 replaced the CS-2 in 1986 and has since then been the only Boss pedal compressor available. This pedal will compress high input signals and boost low input signals to produce sustain. Boosting low-input signal means that noise will be boosted at the same time so it is easy to compress the signal too much and end up with a very noisy signal.
The CS-3 has been through a chip replacement at least once in its lifetime. Early pedals used a voltage controlled amplifier (VCA) DBX1252 but it was changed to a THAT2159 some time in the early 90s. The pedal was modified for the PSA adapter in 1997.
