Boss OD 2 Pedal Burning UP?

[John H]

My Boss OD 2 Pedal just stopped working… when plugged into my amp it hums very loudly but doesn’t produce any volume. I’ve changed out the guitar cords. I am certain I smell or smell something burning when I hook it up to my amp. Has anybody ever heard such a thing? What could be going on? Thanks in advance.

It is a possibility that something burned up but the hum makes me think one of the jacks inside came unsoldered and is grounding. Who knows until you open it up and take a look.

Agree with Bryce. Unplug it from your amp until you determine what is going on with it

If you smell something burning, there is a short in the box

Couple of things to consider as a cause
1. Are you using the correct power supply? If not, you may be putting too much voltage into it or the supply that you are using may not have the correct polarity.
2. Are any of the jacks loose allowing the jack to move about and maybe crack/break the circuit board in the stomp box?

And it could be that one of the ICs or transistors in the box has just run its course and gave up the ghost. It happens

If you will open it up and take picture of it, some of us can give you our thoughts.
Feel free to send me a PM

Could be the power supply as mentioned tbh if any on my electrical equipment smelled of burning the last thing I would be doing is plugging it in to the mains supply.

Thanks fellas for the suggestions. It could be the power supply, although I tried it with a 9 volt battery and got the same results. I will open it up and take a few pictures and share it. Thanks again! Keep on rockin’ in the free world!

If you used the wrong power supply, chances are good you’ve already fried the pedal, so the battery won’t work either.

There are people who specialize in repairing guitar pedals, but I’m not sure it’s worth it for this one, they’re pretty easy to come by used for not much. Might be a good excuse to go shopping!

ha ha, its fried. I just opened it up and it smells like an electrical fire. There is definitely damage in the pedal… and, me thinks its time to get another pedal…

[John H]

Here is the damage… is it worth paying somebody to fix?

The device that is black with a silver stripe on it is a diode and its shorted.

Without seeing a schematic of it, my best guess would be that its purpose is to “clamp’ the
input voltage at 9v so I go back to either the wrong power supply or a power supply that was
the wrong polarity

Can you read a number on it? Should be something 1n40xxx and it won’t surprise me if its not
a 1N4002
