I never did manage to fix mine. re-soldered it so much that the original track near the component I was trying to fit broke from the PCB and I wasn’t sure if i was even able to fix it. Still an unfinished project.

I’ve pin pointed the issue to where I changed a component (he 2N4354) If I touch the joint with a multimeter probe where the two pins are then the pedal starts working. Any ideas?

spoke too soon. It stopped again!

Well I’ve done some fiddling about today.

I changed the zener and now get 6.65V at pin 2 on the 741. I wasn’t getting any readings on the 4558 so i’ve installed a new one of these. But still can’t get any voltage readings here.

Any ideas?

the meter reads 830. Is this normal?

Not swapped it out yet. I found out I needed some more equipment. De-solder pump (just bought one at lunch).

Sorry I realise I’m a complete amateur

Can’t get a reading on pin 2 of the 741. Getting 12.48 on pin 8 on the 4558 (though I’m not 100% sure i’m testing these correctly – sorry I haven’t done this since high school – 18 years ago)

When i’m testing these with a multimeter I’m connecting black to the negative on one of the batteries (is this correct?)

hopefully if I just swap out the 741 it will be back in business.

*fingers crossed*
