Hi, i changed a schematic big muff pi from general gitar gadgets. Oryginal schematic: http://www.generalguitargadgets.com/pdf/ggg_bmp_wiring.pdf?phpMyAdmin=78482479fd7e7fc3768044a841b3e85a

This is my schematic:
It being work?

I don't think your layout (not a schematic) will work. You've put a jumper, where the positive lead of the LED was attached, to ground. You're effectively shorting your power to ground. I think you should just be able to leave the jumper and R27 out.
If it ain't broke...   ...it will be soon.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

If your only reason for the change was to NOT use the LED and to use a DPDT instead of a 3PDT, then all you need to do is remove that jumper (bypassing the LED) and remove R27. Then, wire it as you have it above.

That is ASSUMING this is your intention...  ;D
