Hi

I rewired and rehoused my Blue Box. I had noise issues so I decided to forget about diode and do the true bypass with DPDT. I was barely shocked when I played a note and heard that bypass is NOISY. All the time I hear kinda of fast clicks. They sound like a slow oscillator.

Connections are correct...
Please help me. I've tried even guitar cable with ground...

Could it be fault of one octave mod? (wire!)

Regards
Luke

Well, Id'd suggest you to try first the Bypass scheme in which the input of the effect is grounded in bypass.

Also, I don't understand this, ¿could you please explain?.

I replaced two wires(input jack->footswitch and footswitch->output jack) with a guitar cable. Its ground was connected to effect ground. Doesnt help.

Where can I find this wiring? Is DPDT enough? There are probably no 3PDTs in Poland oO

Yes, DPDT works no problem.
That scheme is all across the net, however;

1 4
2 5
3 6

1 goes to ground.
2 goes to the input of the effect's circuit.
3 goes to the jack designated as input.
4 goes to 3.
5 goes to the jack designated as output.
6 goes to the effect circuit's output.
