Re: show us your home made pedals

Not home made, but GREAT SUCCESS! I bought a dead DD-3 for $20 on YouFaceTwit, and managed to fix it! 4 main issues:
1) incorrect power supply has been used at some point, cooking the protection diode and burning out the PCB. I replaced the diode with an LED as I didn't have a zener, and repaired 3 tracks that were trashed. That got voltage going into the circuit, but it still didn't go . . .
2) found and repaired some awful soldering. Someone has tried to 'fix' this thing before
3) Still didn't go. I started gently pulling the wires coming off the PCB to see if any were loose, found one going to the mode knob which was just barely hanging on. Took it out and soldered in a new wire and boom. Delay was baccck! but no LED.
4) resoldered 4 solder joints that connect the LED to the PCB, and that was back as well.
Feeling rather chuffed with myself. Now to go do all the house work that I was suppose to be doing this morning.
