I put its condition as GOOD - but some people might feel that it is in between Good and Very Good shape.

All Original.

Entered Serial: ZS54823

Your pedal was made in Aug, 2004 (August 2004)

It has been tested and it works fine.

Even though the pedal is about 17 years old and it has been used - it looks good (with light average wear). 

LEFT SIDE - has a couple of tiny & small nicks and a few short scratches.

RIGHT SIDE - has some nicks and some scratches and a couple of very small chips.

FRONT SIDE - has a few nicks and a few scratches. 

BACK SIDE - Near A+. The left edge (when looking at the back side of the pedal) has a few small chips in the finish.    

The small stick with the power info has light surface discoloration.

TOP SIDE - Back edge has a very small chip  Center area has a few scratches in finish, a few very light very short surface scratches, and a couple of tiny & small nicks. The center edge has a few nicks and a few very small chips (really more like nicks).

The TOP BLACK PLATE (where the controls are) has a couple of tiny surface dings / nicks, a a few extremely light very shot surface scratches.

KNOBS -  Mostly fine. The top areas have a few tiny / very small nicks  and / or light short scratches.

RUBBER ON THE TOP - Generally fine. It has light wear on the edges and on the BOSS logo. And it has hardened a little from age. / and from use.

HARDWARE (nuts and washers for the jacks)  - have some tiny & very small nicks and a little discoloration. 

RUBBER ON THE BOTTOM - mostly fine  -  very light wear around the edges.

Most areas of the BOTTOM LABEL are very clean.  The lower center area has a few short creases  and a few tiny nicks. And there are a few tiny nicks here & there..

The GROMMET (the small rubber piece that cushions the front screw hole) has some wear and a couple of short hair-line cracks.

The front black plastic THUMBSCREW is mostly fine with a few tiny nicks.

I took pictures of all sides of the pedal.

NOTE:   There may be some imperfections that I overlooked.   There are some imperfections that can be seen in person that do not appear in the pictures.  Also  - there are some imperfections (glares, reflections. dust specks) that show up in the pictures that are not that visible in person.

The controls are:  LEVEL, TONE, ATTACK, and SUSTAIN.

The jacks are: Input, Output, and Adapter Jack.

More info:  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.


  • 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)


  • Black - Made In Japan
  • Black - Made In Taiwan
  • Silver - Made In Taiwan (the pedal for sale in this listing is SLT)
