This is about the best I can do with the equipment I have, I'm afraid.
You mean the component marked "A" on this photo? I looked under the magnifying glass and there's no visible marking on mine. However, it's labelled "L5" so it's probably an inductor, and I'm guessing from where it is on the board it's going to be there to stop RF junk leaking in/out of the power connector.
Interestingly enough, it looks like they designed the board to take a through-hole or SMD part here. As far as I can tell with just a visual inspection the two pads marked "B" are connected to this component as well so you can use a regular part instead if you want.
So: my
guess is that you can remove the blown part and solder an inductor in (say) the 1-10mH range across the pads marked B.
Unless, as is likely, something else died first and took L5 down with it. In which case, you're screwed.
Please check everything yourself though, preferably with a meter. Everything I've said here is from a 2-minute quick visual check and I'd hate for you to damage the pedal any more.
