JAN RAY PC Design problem

[heyveno]

I take this model and try to make a proper PCB with JLCPB ans EASYEDA. : http://effectslayouts.blogspot.com/2015/06/vemuram-jan-ray.html



I didn't made the schematic because I had made too many mistakes on a previous project, I resumed my single-sided tracing to which I added the footswitch circuit.




But nothing work I have some sound but it isn't overdriven as it should be,I don't understand.

any idea ?

Hi Heyveno, If you have designed this as a single sided PCB then the parts you have added around the footswitch and in/outs etc. have traces crossing over each other. This will cause shorts/connections on tracks that should not be connected.

[heyveno]

thank you for your commnent. I forgot to specify that the footswitch part (up to "Big" + -) is completely double-sided.

Only the "effect" part is single-sided.

also I specify that I made tests bypassing the footswitch part

While I know it seems like more work to have to enter the schematic before you design the PCB, the advantage is that any PCB program worth the name will check the PCB againbst the schematic and alert you to any errors. Of course, you can still make errors on the schematic, but if you draw it out neatly with lots of space it's a lot easier to get a schematic correct than a PCB (which is just a crazed mass of traces going here and there!).

If you've done a double-sided layout, can we see images of each side, please?

it's a "V2" i made larger track and modify one on top
