This is Boss's third and final installment of the compression pedal. They took what they weren't able to do with the Boss CS-2 and compounded upon that platform to create the Boss Cs-3. They have been producing this pedal since 1986 and is still available today. So in 25+ years they haven't updated this pedal.

The CS-3 saw a chip replacement during the early 90's. 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.



Controls: Level, Tone, Attack, Sustain
Connectors: Input, Output, AC Adaptor
Current Draw: 10 mA (DC 9V)
Weight: 400g (15 oz.)
Recommended AC Adaptor: ACA (black label) or PSA (silver label)


The Boss CS-3 will compress high input frequencies and boost low input signals which will in turn give a much better sustain to the notes you on the guitars.. However, by boosting the lows of your signal comes a lot more noise in the circuit. This will increase the amount of noise you hear in the signal.

The compression pedal in general works best with effects such as choruses and delays. This give the needed boost in order for those repeats and lush chorus modulations to jump out in the mix much better.


This pedal is still around today. At new they come in at around $99. That is a good price for this pedal. Not really the pedal I would get for compression, but a decent one nonetheless. I prefer the Keeley Compressor. that pedal is probably the best pedal out on the market today.
