so, i have a nyc muff. love it to death.

however, i was wondering how much it would effect/hurt the pedal to plug it into the 18v instead of the 9v in my dunlop brick.

i know that with some pedals, doing this can permanently fry/destroy said pedal, and i do not want to do this to my pi. but, i dont know if the pi can take the extra load, and i do not know enough about the wiring schematic to be able to tell if internally the pedal can take the extra juice.

does anyone know for sure if this is good to go/definitely a bad idea?

i'm asking this because i dont wanna give it the old college try, plug it in, and leave myself with a busted pi.
You'd fry teh pi.
