Probably not. Why can't you use a 9v one?

Old Boss pedals (marked "ACA" not "PSA") actually need 12v instead of 9v; Some pedals have fancy circuitry that allows safe operation at different voltages: Unless this is clearly stated i'd always stick with the voltage specified on the pedal - It's remarkably easy to fry the pcb, and not always easy/cheap to repair.

Just got my Metal Muff and that's the only spare adaptor I can found around the house!

I did get excited when I found a 9V one but it didn't work, must be old and broken.

Not to worry, I'll just buy a 9V one.

Cheers guys.

Some Fulltones can be run on up to 18V. Your best bet is e-mailing your pedals' manufacturers about it, as some pedals can and some (most) can't. I did that a while ago and all of them (even EHX) answered me within a week.

Selling BOSS FW-3. I live in Brazil, mind you, so prepare yourself for $30-ish for shipping and waiting. Local pickup available, along with beautiful beaches and cheap bitches.

Related question (I don't want to start another thread/waste space).

If I found a 9-volt DC adapter lying around the house (it was for one of those inMotion thingies), can I use it to safely power a pedal?

If yes, can you buy (cheap) 9-volt adapters which aren't made specifically for guitar but will work?

"Will work" doesn't mean "will sound good". Many improper adapters will generate lots of hum. But you can try them. Just make sure the plug is center negative (for BOSS-style DC jacks) or tip positive (for EHX ones).

And how does one do that?

On occasion I do it because I like the sound. I SMACK the my boss heavy metal w/ extra volts sometimes, and every so often other pedals feel the power supply of my Dano Cool Cat (18 volts?!?). I think the possible damage maybe worth the tone. Tell me that when I'm crying about my broken pedals though.

Here's the deal. Many active components like OP amp ICs and such in your pedals will work on a wide range of voltages from around 7 to 15v usually, whatever the spec is. Depending on how it is biased, it will not effect most transistors. What will cause you problems is underated electrolytic caps that may explode and little glass diodes that tend to draw more current than they are rated for. I wouldn't suggest running a power supply on a pedal more than 20% more than the rating.
