    Default Curious about Boss CS1

    I'm just a little curious about an issue with the Boss CS1 compressor that I have seen on two Ebay auctions.

    They say that their pedals have the original momentary LED which flashes on when the pedal is engaged and then goes off again, and that this was part of the original design.
    Is it some kind of pre-80s battery saving circuitry or something? I've never come across this before and I have owned many old Boss pedals, and still possess two Boss CS1s, none of which exhibit this particular trait. In fact, one of my CS1s is one of the first pedals I ever bought, secondhand in 1981, and it has a constant LED whilst switched on.
    Is this a legit design trait or some kind of 'vintage snake oil' patter?

    I genuinely don't know the answer, but it sounds like a fault which the seller is endeavouring to hide with BS. I could be wrong...

    sounds suspicious

    have you found anything on google?

    Personally I would suggest you buy a different compressor all together. Never been a fan of the Boss compressors.
    But if thats what you are after ignore me

    I'm nt actually wanting to buy one of these- but there are two sellers at present claiming the same 'design quirk' (for want of a better description).
    The Boss Area doesn't mention this as far as I'm aware.
    I'm just curious, in an anorak kind of way!

    I thought this was well-known. I've heard about in relation to the OD-1, which was the first compact Boss pedal I believe. An OD-1 was my first ever pedal and I've used it ever since, so I've read up a bit about it and the circuit (different opamps used in it etc.) The very early ones had the LED coming on momentarily when you pressed the switch, but they changed to the more sensible system of having the LED on when the pedal is on very shortly afterwards. I haven't heard of it in relation to any other pedal, but if the CS-1 was produced at the same time I suppose it would have the same "feature".

    No idea why they did it, the battery life they'd gain would be negligible. I think that the first Boss compact pedals might have been the first to feature LEDs at all and having any kind of indicator light would have been pretty radical in 1977!

    Well that's me told! Haha.

    No, this is a new one to me. Thanks for the info. What a strange idea- I'm glad they had a re-think.

    Well maybe not that well-known. TBH I only thought only the very first OD-1s were like this, must be pretty rare.
