    when I turn the pedal off I can very faintly hear the pedal still effecting the signal. Up until this recent problem the pedal has been in working condition for 2-3 years. I had the switch replaced one year ago. I have been using a powered pedal board to supply power to the muff with good results. one thing that i know has varied recently is that the ac adapter that i had been using to power the board crapped out so i matched that one with one of the same ratting from radio shack:
    input 120v ~60hz 0.3a
    output 9v 0.8a

    Any thoughts on what may be causing the pedal to seemingly spill over into effecting dry signal would be appreciated.

    Have you changed anything else in your set up recently?
    More/different pedals in the chain? A different amp? Maybe you’re running your amp totally clean whereas you used to have it a bit crunchy? That sort of thing…

    What I’m getting at, is that maybe the pedal has always done it but you didn’t notice before as other factors were masking the problem.

    I had something similar happen with an old Vox pedal of mine; I had never noticed before, but I suddenly noticed a lot of effect bleed-through. In the end I replaced the switch and re-wired it to get better isolation.
