Hi,

I would like to test 2 pedal I've built, but I didn't receive my order of 3PDT switches..

Here are my build:

I need to connect my input jack to input right? To ring, tip, sleeve?

And output to output jack..same questions.

Thanks!
JP

You should stop everything and build this straight away.

Tip of the input jack to input on the board, tip of the output jack to output from the board, sleeves of both jacks to ground on the board.

I have a hard time figuring how to wire from sabrotone layout and GGG layout. How should I wire Volume 1 and 2.

And should I join jack ground at board or go from one jack to the other than to the board? What would you do?

For the fuzz face volume 1 connects to fuzz 1, if you look on the layout fuzz 1 connects to the ground row, so volume 1 also connects to ground. Volume 2 is the output.

I normally connect both jack sleeves together and then connect one to ground on the board, it does not really matter so long as they are both connected to ground in some way.

So if I want to test it without a 3PDT, I need to connect volume 2 to output jack tip?

One last question, on the fuzz schematic, if I want to remove the battery plug, what do I have to rewire?

Thank you very much!

You just don't connect the battery. You don't have to rewire anything, as long as you're following your layout.
If you want the input cable to connect and disconnect power, though, you can connect the black wire connected to the DC jack and connect it to the input Ring. (but remember to connect the the PCB to ground after disconnecting it from the DC jack..)
