    The first time its battery started to run down, I just plugged it into a power supply I had lying about, without really looking at the adaptor. Now I’m thinking that was a pretty serious mistake because, after reaching a point where I basically can’t get any effect out of it at all, I looked at the adaptor, and it’s 9v, 500mA.

    Have I fried my pedal?

    9V 500mA DC is fine for the pedal, a pedal will only draw as much current as it needs so a high current supply isn’t an issue.

    However, if the supply was outputting AC power rather than DC or its polarity was the opposite of that required that certainly could cause harm.

    Do you have a clear photo of the power supply in question?

    I apologize for any eye strain; the image is an extreme close-up, cropped to meet the file-size limit.

    Okay well that’s a 9V DC 500mA Center negative supply.

    Does your big muff have this style power connection? http://www.kitrae.net/music/Images_Secret_Music_Page/IMG_2253.jpg i.e is it a big box model and if so did you have to use any kind of adapter to connect the supply or does the adapter have the 3.5mm power jack as standard.

    The first NYC Reissue Big Muff has reversed polarity.

    It is a big box model, but the power jack doesn’t look like that. The adaptor plugged straight in, no other parts needed.

    Okay well unless EHX made a change I don’t know of (possible) that’s been modded by someone.

    Assuming they modded it correctly, your supply shouldn’t have hurt anything.

    I received the pedal as a gift, Christmas 2014 (the Christmas before this past one). I’m as sure as I can be that it was bought new-in-box. O.o
