Hi One-Way
For starters, I would solder the blue wire back onto the PCB.
It might be your main problem.
Are the terminals supposed to be bridged on the overdrive pot? (See pic)
The link on the pot is a common technique, it's wired as a variable resistor, and only need 2 of the 3 connections.
The do this to stop noise getting into the circuit & it's also good circuit practice, to no leave pins unconnected.
Does the output jack need a separate earth wire or is the case earth enough?
You are correct, it works through the earth on the case,
but because you have it disassembled, you will need to clip on an earth lead to it, for testing, out of the case.
Let us know how you go, after you solder the wire back on?
And keep Sinkfoot's advice, for an earlier posting in mind, if you are still having trouble.
Good pics by the way..
Regards Dr. Bob
PS - looks like the soldering, on the #(1) Brown wire, might be a bit poor as well,
or it's frayed a bit, just by what I can see in one of your Pics. |

I soldered on the blue wire and tested it and it checked out OK. Then I reassembled it and the LED wouldn't light. Opened the back and a couple of wires had broken off the input jack. I re soldered another couple of broken wires that came off the PCB and put the back on again and the LED was working.
Plugged it all in to my amp and Voil� shes singing the blues again and working perfectly.
Just goes to show with a bit of tweaking of wires while reassembling showed up all the poor connections. I scraped the funny looking track and it clean copper underneath so is fine.
Thanks to all that spotted the initial problems. |

Hi One-Way
  
Next time you play, tell em, this next one's for Bob....?
I will sent you an Official Pedal Tech certificate.
Now go back to, or call the place that sold you the Shonky pedal,
and tell them you fixed it, & blow a raspberry. 
Seriously, Congratulation on getting a true classic pedal singing again.
Regards Dr. Bob |

Congrats on getting it going again. Guess there were some other bad solder joints with all the resoldering you did.

 I wish I could solder...
I'm too scared to trying. I might ruin a pedal!!! |

Soldering is not difficult but you must have a soldering iron with the wattage/tip size suitable for a job such as electronics so you dont overheat the components the iron tip is in contact with.
Always coat (tin) your wire with solder first, put a little on the tip of the iron, hold the wire in place, touch it with the iron tip just long enough to melt it together and its done.
Best way to learn is to practise soldering wires together, and soldering wires to old PCB's etc before trying it on your favourite vintage Boss pedal. |

ronster..i'd have a go..i managed to fix my boss tuner,the input/output is soldered to the pcb and the input was broke and i don't use the output so i desoldered it off the pcb stripped the input and resoldered the output back in it's place,and my 15 year old tu12 was back working....i've also done some jobs on my amps i.e changed pots etc... and rewired some of my guitars with new pickups and i've no prior experience in electronics...and to be honest i got a great kick out of it,a great feeling when you fix something and it works......well done One-way enjoy the OD1...... |

Thanks Franzoni,
Those copper wires work harden with age and get more brittle so hence they will break off right next to the connection easier.
Do the new Boss pedal wires solder thru a hole in the PCB or sit on top in a blob of solder like the OD1 does? It does make it slightly trickier to get the wire lined up and hold it in place till the solder solidifies. |

Hi Ronster.
Come visit me one day, I'll give you free lessons, serious.
I teach this as part of my daily work, to our apprentices.
And I was the Training Officer at the (M) Phone company for 7.5 years.
Bring some faulty stuff & good chocolate, cheese or port. 
You live about 15 to 20 mins away....
Regards Dr. Bob |

Hi Strato
Maybe by soon to be implemented Video link or Net(Pod)cast.
Unless you want to pitch in for the air fares....
And I'll throw in 3 pedal fixes..
