Just ran into this problem. When the pedal is off, there is a dry signal. But when I turn the pedal on, I get nothing. Not even a dry signal. I've already tested the cables, and tried various input configurations but nothing seems to work.
How would I approach solving this problem? Thanks in advance! |

mine too! 
i found a guy on craigslist who buys broken gear. i'm selling it to him for $25 and putting it toward a new (used) oc-3. unless he manages to fix it before i find another one, in which case he's going to sell it back to me for whatever the going rate is on ebay. that's the only suggestion i have. |

Sorry to hear that, but at least I know I'm not the only one.
I found out that there is a faint distorted sound thats only audible if the amp is turned up. |

I've had this a couple of time on my bench. While it is impossible to tell without testing it, the most likely cause is a failure of the output opamp. This occurs sometimes for no reason, and sometimes because previous owners do things like plug an amp output into the output of the pedal (this is true! I have one at least where this actually happened...).
Anyway, I've had three recent manufacture pedals with blown opamps. If if is that, the good news is that it can be fixed. The bad news is that it takes specialist equipment or great patience to deal with the SMD chips. |

@Jack
Funny thing was, it was working well for about 30 minutes, then all of a sudden it started feeding back and then wouldn't work at all.
@Laurie
Thank you very much for your reply! I was hoping it would be something I could fix myself, but I guess it's better to get it serviced than create some induced failures. |

If it is under warranty (less than 5 years old) caontact Roland. If it is older, your local guitar shop will have (or know of) a tech. |

thanks for the tip, laurie!
if it is the op amp, how much cash am i looking at for a new one? you said it takes either specialist equip OR great patience... i have one of the two (guess which?). can you briefly explain what kind of torment i'd be putting myself through? |
