So I found an old boss OBD3 in storage today. It's probably about 15 years old. Anyway, I go to plug it in and play it and it doesn't work properly. I can hear some noise coming out of my cab when it's engaged, which is the pedals distorted sounds but it's I'd barely audible. When disengaged, I get absolutely nothing. Is there something I could do to this pedal to see if I could fix it myself. I'm confident I could solder something if need be but I wouldn't know where to begin. I tried taking the board out of the bottom but it was in there pretty good so I only got it partly out and put it back in and figured I'd run it by my good friends on TB to see if you guys had any recommendations.
