Hello everyone,
as this is my first post, I�d like to intoduce myself.
I play Guitar and Bass for almost 20 years and I�m a real Boss Aficionado.
Here�s my question: I recently purchased a plastic screw Boss CS-1 at ebay. Price was OK, soundwise I�m content. There�s only one problem: if the effect is engaged, volume drops quite a bit. Even if I turn Sustain and Volume all the way up, the uneffected sound is still louder! In fact I wanted the effected signal to be slighlty boosted. 
This cannot be normal!
Any expiriences with your CS-1�s??
Kind regards,
Christoph |

| I've got a CS-1 coming in the mail this upcoming week (plastic screw) I'll let you know, it is possible that your photocouplers are going bad, and that they need to be replaced as this pedal works on those unlike the CS-2 and CS-3. Although I have been unable to find information on what type of Photocouplers are in the CS-1, but after I get mine I will post about it. |

Hi Bassan and welcome to the forum. 
I believe the volume is supposed to drop a bit in the CS-1. With the sustain at max, a 1kHz input level at 0dBm the specs says you should have an output level of -15dBm. If the input is -20dBm you should have an ouput of -17dBm. How big is a normal input signal? Anyone?

Thanks a lot so far!!
I hope you can�t tell that it�s the same with your CS-1, Dingus; for your sake. Isn�t it always handy to have some headroom to boost your sound with a pedal!?
Nice to be here, Bossarea! Where did you get the information about the In and Out levels of the CS-1??
Kind regards,
Christoph |

I don't have a CS-1 myself so I can't compare the output.
The ouput level is given in a table on the CS-1 schematic. |

Hi Bassan,
I do have a CS-1 and will do the output check later in the day.
Have had the pedal only recently but what you mentioned seems to be unusual but will do a good check and let you know soon as I am able to.
Cheers. |

Hello Bassan, here it is:
I assume you know how compressors work, anyway, most of them are able to boost or cut your volume. You can use them as a compressor [boost low signal, cut louder signals] and you can use them as a limiter [ cutting your signal when it hits a certain point]
Okay using the CS-1 you can cut your level, the controls need to be set like this:
Level: let us say midway
Sustain: turn knob anticlockwise
In this mode you can achieve a drop in your orginal level.
Once you turn the sustain midway and even further you will boost your signal.
The treble mode will also boost your signal, just keep controls all midway and put mode into treble and your your signal is boosted a little, turn the sustain clockwise and your signal will be boosted even more, even without turning level up, once you open up the level and sustain knob you will be boosting your levels a lot.
In the manual it says that the CS-1 can boost or cut up to 15 db. however it does not feel like that to me, seems overal, the pedal is pretty smooth, yes you can boost your levels, but it feels like a moderate level boost.
So all in all, if your CS-1 lacks in any of these operations then you do have some trouble with your pedal.
Just check the controls, and also your gtr. controls, make sure they are all full open [even the tonecontrol, as this does makes a difference to the overal feel of your levels]
Sorry for my long discriptions as I am not really sure how much experience you have with compressors or limitors.
just one more question: Did you use a ACA powersupply? Were you using a battery? Should not really make a difference, but the CS-1 does prefer a ACA instead of a PSA powersupply.
Okay let us know how you are getting on with your troubleshooting.
Cheers |

Thanks for your replies!!
As I said: it cuts in every possible setting. I tried both with battery and adaptor, no difference. Maybe it�s really wear of the photocouplers?
Kind regards,
Christoph

Could well be, hope you will be able to repair it or replace the CS-1 for another one as it is really a great compressor.
Cheers |

| I can not get any information on the photocouplers (HTV P873A). It might be very difficult to find matching types without a datasheet. |

Hmmmm have a feeling it may be easier to buy another CS-1, may be as cheap as going through the whole repair-route, unless you know a good repair-guy in the area where you live.

| Don't give up hope yet, I've been waiting to hear back from him, but I e-mailed our good friend at Small Bear Electronics as I found a japanese article that says the VTL5C3 that he carries has worked in place of the Photocoupler you mentioned. Hopefully he will know if this is fact or not. But if yours dies what's the harm in experimenting anyway and trying different photocouplers out. If I found a cheap dead one to buy off of someone I would try it. But I'll let you know when I hear back from SD @ Small Bear. |

Boss CS-1 is rather low on volume
