Can I run a 12v pedal with a 9v power source?

I use those 12v's I got (they came in a pack of 5) to run my Keyboard.

For whatever reason - not loving this pedal. Like I said - could just be "that" adapter. I can try another when I dig one up.

It may be the whole Mv issue too. The One Spot is 9v, but high Mv, whereas the 12v is low Mv. Or whatever that second important number is.
 
The 2nd number is the amount of current it can supply, if it's less than the pedal needs it could be dragging the power supply down. You should be able to find out what the pedal needs in the manual or manufacturer's website. The current is as important as the voltage.
 
This is, how shall we say, a "vintage" pedal no longer in production. Didn't come with a manual.

That said, I know the pedal is a 12v/200Ma

The questionable power supply only says 12v on it. No Ma listing.
 
I have a Trutone power brick. Said pedal is not on that board. It is just a free-standing random pedal.

Just get a proper clue dude.
Unless it's such a rare item as to make the cost prohibitive, I would just get the correct power supply.

If you have a proper power supply then hook it up to the pedal. Then you know if it's working correctly and sounds the way it should.
 
I have a few of those laying around. to a problem. Let me check it out.

FYI - tested another 12v; No sound, no LED, but I get a digital bleat. So it is definitely those AC units.
 
You keep saying 12V, AC or DC? An pedal that needs and AC adapter may probably run on a DC adapter, but not the other way around. If it's a vintage pedal, why take chances, just get the right one.

It is from the 90's. Not that "vintage" LOL
 
My Decibel Eleven Hot Stone Deluxe has two variable outputs.

I have one too and it's great .
I can run a Tascam CD-GT2 Phrase Trainer, to jam along with on a extra Crate Power Block or learn music with .
The CD-GT2 uses 5 volt of power and I used the Hot Stone Deluxe's 5-9 volt adjustment knob to power that Tascam CD-GT2 device .

The DE Hot Stone Deluxe also powers my DE Loop Expander, that is designed for 9 volts , but I have been using the Hot Stone to pump in 12 volts and it works just fine .

I knew a fellow who had a similar issue
his 12 volt pedal didn't work with his 12 volt supply

The multeffects pedal wanted 12v ac not dc

Worked just fine with the correct power

I have had a boss DR drum machine that listed a 14 vdc power requirement but worked just fine with a 12vdc

My Behringer FC volume pedal wants 12dc or else
