Mach1 Clipping question

If I wanted to put 2 of the stock diodes and the other side of switch a pair of germaniums on a dpdt on/on how would you wire it in? I just did a straight up build and put the two wires to middle two lugs of the switch to diode 3 on the pcb and did not populate diode 4... did i do something wrong because my build has zero volume.... just wanted to see if I populated it correctly and possibly have some other mistake..
 
D3 & D4 are in series. You put the diodes on the switch in parallel.

Compare the schematic to your board/layout closely. You need to move one of the wires going to the switch too. D3 anode and D4 cathode should have wires connected.
 
I was in a hurry when I typed my previous reply, sorry if if doesn't make much sense to you.

The way you have the switch wired isn't correct, but shouldn't cause loss of all sound at all times.

The diodes on the switch should be in series same as D3 & D4 are on the schematic. Probably easiest to mount them "tent style". When you run the wires to the switch be sure to wire switched anodes to D3 anode and switched cathodes to D4 cathode.
 
I think you should've put this in a troubleshooting forum ;)

Quickly looking at your wiring, I think you've just connected D3 to the switch? That's not going to work here (unless you only wanted to sub what is in D3, but looking at switch I don't think that's what you intended).

Can you describe what you're actually wanting to do and we can give more advice. The way you've wired the diodes to the switch, it looks like you want to replace all the clipping with what's on the switch--if so you'd need to take a different approach (for example one side of the switch to D3 and the other to D4, which would probably do what you wanted, but would also render D2/D5/D6 useless because you'd clip before they come into play).
 
You want your wire taps to go in the anode of D3 and the cathode of D4. As you have it wired right now by just tapping into D3, the signal is still expecting to go thru D4, but there is nothing there.

No sound at all is usually when the audio lead is shorted to ground. Did you have bypass? LED?

I really just wanted to have some clipping option on a switch to have a different flavor... I figured since d3&4 were together in schematic as the symetrical half it would be easier to combine those two togetherD3D4 on half the switch and the other half some germaniums for a different clipping sound.... But I do see my thinking is wrong because they should both be pointing same direction...
I just finished populating another pcb since the first one had an issue.... I got frustrated and chucked the other in the bin..... took the easy route and whooped up another but I haven't populated the diodes yet...
