How do I fix my DOD FX25B

[sohamorrohit]

I just got a DOD FX25B I bought used off ebay. But the thing doesn't seem to work.
The only thing that happens when I engage it(the LED does switch on so I'm sure it's turning on) is a volume drop. There's no filter effect. At all. What could the problem be? And is it repairable?

P.S: I run it on a 9 V battery. Oh and the warranty's invalid now. So I can't return this.

First I would contact the seller - if they sold you a bad pedal you should be able to return it. Beyond that, email DOD and see what their repair service would cost or see if they have a local dealer who can repair it.
