New pedal builder here for some help

[kierkegaard]

hello guys!

have been building some eurorack modules and putting together some partscasters so naturally have gravitated towards building pedals!
enjoying building some of the fuzzdog kits and just had some bread board arrive to start trying out building a circuit from scratch to really understand whats going on.

so far all but 3 of my pedals have worked a treat and i was wondering if someone would be so kind as to give me a hand with troubleshooting them. I have a multimeter and have worked through a couple of eurorack modules with guidance, Can look at a schematic and follow a chain of continuity.

but without really knowing what im looking for feels like im stabbing in the dark, so wondering if someone could point me towards some basic steps in troubleshooting, where do i start and how do i find the problem.

more specifically these are the pedals that arent working

Hope im finding everyone well and fingers crossed be an active member of this forum as I live a life full of pedal building, I dont even really care about having these pedals working, im more interested in knowing why they dont work and learning how to find those issues myself!

there is alot to learn so please excuse my ignorance, hope someone can help me out!

Welcome. There's a sticky topic in this board named "DEBUGGING - What to do when it doesn't work". That's the place to start.

aaah ace!  i thought there would be something like that but i was searching for 'troubleshooting'

nice one, appreciate it

Welcome!

I suggest you to create a separate topic for each pedal. Post the link for the project, a few photos, and also the voltage for all pins of each transistor and ics. Measure the voltages with the black probe connected to ground.

I'm sure we can help you.
