Yesterday I was experimenting with connecting my DC 9V power supply to new sockets at my room while it was plugged to my Sansamp BDDI (which may have been quite dumb, I must say).
After plugging it in and out of the sockets, I came back to practice and... well... my bass pedal wasn't working really well. It still powers on, but it barely outputs any sound other than LOUD popping and cracking sounds as my bass dry sound disappears with the blend. It occasionaly still comes back to normal operation, but it's quite instable. Bypass is OK, no problems with that.
Already tried soloing a 9V alkaline battery, same thing happens.

I purchased this pedal 2 weeks ago at a Guitar Center store in Orlando with a discount from display model (didn't came with the box/manuals/etc), and they charged me separately for warranty, which I didn't pay for because I had no extra money. Summarizing: it's brand new but it's not under warranty.
What should I do?
Edit: I also have a MXR M82 Bass Envelope Filter which was also plugged during the sockets thing, but this one is 100% OK... (if that helps with anything)
