Sorry man,
but it's 3 weeks....
I mean, you had the time to trace the pedal.
At least it's what I do (it's my job BTW) when I have not the schematic and I must repair something.

Even with a scratch schematic many fellas here can suggest educated guesses...

Yes, it's your job it's fine.
But it's not my job and I never said I will trace the circuit.

I asked help relating to schematics and guts shots.

thanks

You can lead a horse to water but you can't make him think for himself.

I gave the lad the answer, you can clearly see in the two pictures I linked to that those wires should go to the jack , if I am wrong and they are connected to something else, instead of saying I am wrong . Tell me where they connect

With answers like you are giving you will get FA help as you sound like you are just having a go at people for trying to help.

I asked you for photos early on in this thread, well if you cant be bothered to post some good quality photos then what do you expect. :slap:
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

Giving an answer is different than giving a right answer, you made a wrong assumption.
I will tell you for sure what wires and how they connect to the jack as soon as I know, you have my promisse.

Be aware that I never asked for your help.
I asked for gut shots of the pedal, particularly the Out B jack connections and wiring, or schematic.
You are taking the thread to another direction but I still only need what I've asked in the 2 first posts.

The photos of my pedal don't matter at all Ice-9, if the jack is not connected that is no info that we can get that we cant get from the pictures in the Japanese site.

Anyway, even not helping at all I will post them as I told, I have been recording at the studio all week long and don't have the pedal with me as I told you before, but I will take the pictures as soon as I can.

Thanks Ice-9 and Dirk_Hendrik,
I will probably get some gut shoots of this pedal soon enough and will let you know. if you know anyone that has this pedal and you can take a couple of shoots that would be great Help.

Best Regards

Whats the problem you're having with your pedal?

My pedal was working fine, it was only the Out B jack that was removed by a previous owner and not connected.
I was able to wire it easily with pictures if that jack from a working unit.

I have some schematics of other pedals of this series although I was never able to get schematics for the DSC-20M.
