I had rehearsal last night with my big band and as usual I only brought one bass with me, an ESP Vintage 214 passive PJ bass. I got everything setup and plugged my bass into my tuner. The tuner didn't respond. Huh. I checked the knobs and output jack. No dice. I plugged into my amp. No sound. I unplugged from the bass and touched the tip of the cord and it made the usual noises. I swapped out cables, but still no sound. I borrowed a screw driver from the drummer and looked at the output jack. Everything looked soldered correctly and firmly. So before I take the pickguard off and start digging....what should I expect? My best guess is there is another wire internally that came free. HOW it came free........I have no clue. So what did I do for rehearsal? Well I had my tuba with me for brass ensemble rehearsal afterwards. I played all my bass parts on tuba. In honor of Maurice White, we played "September" and yes...I played the bass part on tuba. Funk tuba is not usually my specialty, but it sounded decent.
