Just got a complete active EMG J-set. It was used and came out of another bass (eBay deal) and something isn't working right. I went over all of the instructions to the T and there are no weak spots in the soldering. most of the set was already complete. All I had to do was solder the pup ground wires and connect 4 hot wires. Two from pups, one from acive circuit and one from the + battery lead together. Those look like a cluster but is for testing only. I'll re-do it if all works I made sure the pup wires did not become detatched I get nothing. I can hear the slightest change in some cable hiss when I increase the active treble dial but thats it. No noise from tapping on the pups or hot connections on the vol pots. The pic isn't the greatest but see if anything looks off. The only thing extra I did was to add a ground wire from the pot ground to the bridge.
