Wiring Clean/OD DPDT toggle

[titser_marco]

Hi guys;

I currently wired up my build with a DPDT for the clean and OD switch and used this wiring schematic:



However, one thing that I noticed is that whenever I switch back from OD to clean, the signal doesn't go through, i.e. it goes silent. I'm only able to get it back running if I hit a loud chord.

This leads me to think that this may not be mechanical issue with the switch but some signal issue that gets "refreshed" when I hit a chord. I googled some DPDT schems as well as the ODS 183 schematic and it seems like it uses this method of wiring the DPDT instead:



Is my hypothesis right? And if so, can someone explain to me what is going on here electrically?

Hi Marco,

to me it sounds like a bad solder joint. I cannot explain why conduction is restored after hitting a chord, but I had the same thing with a pickup selector in a guitar. After resoldering the switch the issue was gone.

Obviously the wiring in your 2nd pic has the advantage that the input of the OD stage is grounded when it´s disabled.

I see. OK let me see if reflowing the solder works. Noob question: why is it an advantage that the OD section is grounded in the second wiring scheme?
