A few months ago I bought a GEB-7 EQ pedal off of ebay(obvious mistake), and it had been working great until last week. It went unused for maybe 2-3 weeks while I worked with only my amp's built-in EQ, and last week after buying a new bass and wanting to try it with my pedal, it didn't power on. I figured no big deal, just put a new battery in, but after doing that, the situation was the same. I know I made the wrong choice by buying from Ebay therefore forfeiting the Boss 5-year warranty, so now I'm wondering if anyone knows what the problem might be? It doesn't power on, and no sound runs through it at all. Thanks in advance.
