I fried two of my pedals. How likely is it they can be repaired?

Not sure about Aguilar because the new ownership, but Darkglass will take care of you. In fact, I'm surprised that it didn't have some sort of protection to prevent that so there may be other issues, maybe with your power supply.

 

Ouch...............

 

Perhaps there was protection.

@BeorhtDana
If there was a protection diode, the excess voltage would have burnt out the diode, like a fuse. If so, you'll have a handsome paperweight until that protection diode is replaced and then see what, if any, other damage may have occurred.

Even with a protection diode, enough juice may have got through in the time the diode took to burn out, and fry something else such as a chip.

Have someone local to you look at both pedals and the PSU, hopefully DG and Aguilar are amenable to supplying your local shop with the info needed to make the repairs.

PS: Since they're out of warranty, care to show us a gut-shot? Maybe it's visibly obvious if a diode is burnt, magic-smoke smell etc...

 

I would at least check the voltage on each tap on the Power Supply with a Multitester.

 

Just saw this. Interesting. But now Korg owns DarkGlass. So who knows what will occurr.

 

This is why I wrap the heads of my 18v connectors in red electrical tape- so they don’t look the same as a 9v! Tip for future
