I just got a Morley Bad Horsie Wah, and i was wondering if i could plug in this adaptor i found laying around into it. The wah simply says "9v" next to the jack. I plugged in the jack into the wah without any power running through the adaptor, and it fits fine. Here is the info on the jack:

"Switching Adaptor
Model : ADS- 18c-12
Input : 100-240V- 50/60Hz
Max. 0.6A
Output: 9V --- 2.0A"

Do you thing it's safe to try to power my wah with it?

Yes. The wah will only draw the current it needs. The only thing you have to worry about is the jack being the right polarity.
