Baking pedals

[Nickosaurus]

So I stripped the whole pedal back to just the switch and jacks and I'm still not getting a bypass signal. I've checked continuity following the hot wires and grounds and they all connect. There's no ground/tip continuity between either jack and I have ground continuity between both jacks.

This is the second footswich I've used. They're cheap but I've used in the past with no failure rate. Is 2 in a row probable?

Or is there something wrong with the diagram?

Is there an easier way to make a breakbox for a circuit testing rig?

Are you on the message board at Aron Nelson's site? If not that's probably where you need to work through these issues. Mike Fuller, Zachary Vex and a whole bunch of other guys are members who know pedals inside and out.

Double-check that the switch's contacts are working, as it's possible to cook it while soldering and be left with a non-conductive lug. From the image in a previous post:


In one foot-switch position you should get continuity between the two lugs in the blue ring and continuity between the two lugs in the yellow ring, but not the red. In the other (bypass) position you should get continuity between the two lugs in the red ring, but not the blue or yellow. Check the other lugs if you want, but the above are the ones related to the bypass.

Okay so the switch is behaving as it should. Red by itself in one position (let's call it Position 1), blue and yellow no red in the other (Position 2).

When I plug into my amp, position 1 lets the sound through however position 2 there is no sound coming through.

Does this narrow our troubleshooting?

Red, aka position 1, is your bypass position. Position 2, blue and yellow, is your 'external circuit' position... that's where the signal passes to your terminal strip to go through whatever circuit you want to test. You will only get sound from position 2 when a complete circuit loop is in place (or if you short in/out on the terminal strip). So, looks to me like it's working exactly as intended.

I have a bad feeling that it has been correct the whole time then... Bloody hell haha

But then it's a good thing that it works!

Hi Nick,

Finally got to read your thread start to finish. Looks like you are on track now. If you are interested, I found that the following youtube tutorial explained the footswitch bypass wiring pretty clearly. Once I realised that the bypass was just a simple electrical connection straight from input to output it all made sense. Hence *bypass*. Damn my brain. Anyway, might be of interest to any non EEs out there (of which I am one).



cheers,
Gav.

Mate I just feel like an absolute idiot right now. I assumed a bypass signal meant I'd hear my amp on both the bypass and the engage. No idea why I thought that either because it's completely illogical but we do live and learn as they say. Seems I'm sort of not as hopeless as I thought at wiring... It worked first try!

Finished with a 5 minute sketch.

I think the name is suitable
