I’m hoping this is something simple! 1st time poster, so hopefully i won’t super noob, but i may.When i engage the pedal i can here the sweep, the only thing is there is no guitar signal in either the off or on postition. Plenty of sweep, just no guitar. The build has got pretty messy as i’ve been simplifying it to try and trouble shoot what’s gone wrong so i went away from a 3PDT bypass and an LED to just two rows of lugs hoping i might have got something wrong there, but no. I realise the oritentation is incorrect, it’s just rotated 90degrees in the chassis (i’m certain). Anyhoo, all help appreciated.

BillyModeratorAt a quick glance your solder joints on the switch look ball like reflow the joints for around 4 seconds until the solder flows nicely
If you’re not getting bypass or effects signal that points to a fault more than likely on the 3PDT switch so I’d start with reflowing your switch joints and in and out jack solder joints that also look dry
Be careful with the switch it’s very easy to damage with too much heat
Its very difficult to trace your wiring but from what I can see your in and outs from the pcb to 3PDT are the wrong way round ignore that for now reflow the joints advised and see if you get bypassed signal

BarryKeymasterTypically a problem like this is in the off-board wiring.
I am having trouble seeing clearly or trying to make sense of the 3PDT wiring scheme and see what is going to where in regards to the audio path.
If someone else can open their eyeballs any further pleas jump in.

InactiveAfter reflowing, trying different combo’s on the 3DPT, it turned out to be one of the input jacks……………. shoulda looked there first! I suspect i grabbed ones that had been used before, and probably should have been binned. Thanks for the attention folks. The MoWah is lovely! Next project!

BarryKeymasterYou should look at Wilkies Wah Guide on the Guides Page before moving on and try a few mods.
