When I plug my guitar through the pedal, it makes sound when the Thunderpuss is bypassed, but when I turn it on, there is no sound at all.

This is my second build, and the first one didn't work either. I scrapped it and tried this one, doesn't work  Help save my faith in building pedals!!

This is a messy photo but if you anyone can see a problem right off the bat, let me know:

Thanks for the responses mgwhit!

I tried your test to see if the probe is working and it appears that it isn't

I followed Jacob's specs so I'm not sure what I did wrong

I have the probe grounded, yeah.

I am almost sure that I have the wiring correct and I resoldered for cold joints.

So I should have no continuity to the ground wire from any point? and if I do have a spot grounded, how do I fix that? You mentioned some parts should be grounded, how do I know which?

I apologize if these are amateur questions, I'm a complete beginner

I built the probe and bought a multimeter. I have no idea how to use the meter and when I use the probe, I get no signal at any point on the board, even when I touch the probe to the input point.

I am getting really frustrated with this. Does anyone have some advice for me?

Thanks!

Does anyone know if I need a stereo or mono jack?

Stereo or Mono jack? Does it matter?

I think I could definitely do this if I go buy a jack from Radioshack

By desoldering the board from the enclosure I meant desoldering the wires attaching the board to the input/output/dc/etc.

I'll see if I can find someone I know with a multimeter.

What would the specs be for making the probe?

I saw that post that jkokura made about building a testing rig, but is there a simpler way to do it that wouldn't involve desoldering the board from the enclosure?

I don't have a DMM and I'm not sure if I want to invest too much money as this is my first project and I don't know how long I will be involved in this hobby.

Would the audio probe option be a cheaper solution?

Still no luck!! I tried the braid and cleaned everything up with the xacto.

What tool do I need to check continuity? Maybe it's a faulty part

I got one of the desoldering bulbs and it didn't help too much (one of these: http://rsk.imageg.net/graphics/product_images/pRS1C-2160655w345.jpg)

I guess I'll go buy some desoldering braid. I hope this works!!

So should I try the xacto knife method first or buy the soldering braid (not sure how this works, I'll look up a video tutorial)?

Will the knife be able to scrape away the solder? I would imagine it needs to be melted for it to budge at all

I tired desoldering (with a desoldering bulb) a few of the points where it looked like bridges were formed but I didn't have too much luck. It looks like they are still there. Can anyone look at this picture and tell me what I should do?
