| Ahoy, the search feature wasn't working so if there's a thread covering my question already I apologize. I have a Boss Super Distortion and Feedbacker, made in Japan and it seems to be malfunctioning. The light comes on very faintly, and I don't get much of an output. It basically ends up sounding like noise. I had been using a standard 9 volt adapter with it, which I've now come to realize may not have been the best idea. Anyone have any other ideas, and/or caveats of information about things that typically go wrong with these guys? Thanks. |

Japanese pedals are usually ACA series, which is 12volts. Have you also tried a battery?
Sounds to me like you are probably just using the wrong supply, and the pedal might work fine when you correct this.
ACA pedals (MIJ & early MIT) = 12v DC Center negative power supply / 9v battery
PSA pedals = 9v DC Center negative power supply / 9v battery |

Hi r0flmywaffles, DasBeef & Guys
Like DasBeef just wrote/mentioned,
It does sound like a typical not enough voltage (ACA running with a PSA) supply problem.
Retest it with a "KNOWN GOOD" Battery.
If it runs ok, then it is the ACA-PSA problem.
If it's an ACA, & you have apother boss PSA pedal,
then you can use the daisy chain second pedal trick to power the DF-2.
Or if you are handy with a small soldering iron, you can mod it for PSA use.
Worst case:
If the LED on your DF-2 still does not light correctly, it may have a partially shorted protection diode fault, which can also be repaired easily.
...in this case, also check to see if the Battery is getting hot, which indicates a short or partial short.
Perhaps the power supply you were tying to use was off-spec., or not working correctly.
Regards Dr. Bob

| I do recall using a battery, but I'm not entirely sure how new it was. I'll have to pick up a fresh one and attempt it. I had heard the bit about daisy-chaining the two pedals, but hadn't given it a try yet. I'll also check the battery for temperature in regards to that second thought. Thanks. |

| Alright, so the pedal appears to be functioning properly now with the use of a 9 volt battery, but it creates an absurd amount of noise, almost to the point of being unusable. Now, I'm thinking this could be because I had disassembled it entirely to check all the wire connections and solder points and when I tested it with the battery, it wasn't in the case and probably not grounded properly, or something to that effect. But any other words of advice would be appreciated nonetheless. |

It should be fine when re-assembled in the case, the in and output jacks should always be connected to each other, normally through the casing. |

Yep. If it is disassembled, run a wire from the sleeve of the input jack to the sleeve of the output jack and it should sort it out. I usually use a lead with an alligator clip on both ends and clip it to the appropriate lug on each jack.
