Topic: ShoBud single coil PU question? |

| I replaced the original single coil pickup in my Shobud LDG with a new PFII. The pickup in the guitar worked great and sounded fine, I just don't like the noise. When I removed the pickup, one of the wires came loose. There are two, one that comes from the center of the pickup and one that went to the outside, under the tape. The wire that detatched was the wire running to the outside. I very carefully removed the tape, and don't really see anywhere where the wire attached, just the very fine copper coil. My question is, "Where specifically does that outer wire attach to? Does it just lay against the the side of the coil? Which of these wires is hot and which is the ground?" |

The wire that came loose is the ground wire. The center wire is the "hot" wire and should ultimately go to the tip of the 1/4" jack. Sho-Bud used to ground the pickup and changer together and with the changer mounted to the end plate the ground was carried through to the 1/4" jack.
Most guitars don't ground through the changer that way and run the ground wire to the ground lug on the output jack. |

| Thanks. On this guitar I had to run a small piece of wire from the changer to the endplate(underneath the guitar about 1/2") for either of the pickups(didn't matter). If this small wire is not connecting the changer and endplate, I get all kinds of popping and cracking when I touch the knee levers or other metal parts that ultimately attach to the changer. Where on the single coil pickup do I reattach the ground wire? Do I just lay the tip against the coil and rewrap the tape? |

If you are running wire to ground everything together, it should all go back to the ground at the 1/4" plug. You shouldn't have to connect that ground to the pickup, like the original sho-bud pickup was wired.
Just make sure everything is grounded together. Run the ground wire from the pickup to the ground lug on the 1/4" jack along with the wire you used to ground everything together. That should take care of it. |

Jack,
the way I understand is that the wire at the other side came loose, directly at the pickup. I think it should be soldered to one end of the copper wire at the spool. I don't know if it can be fixed easily. You might ask Ed Naylor or Bobbe Seymour.

| Marco, he has replaced the original Sho-Bud pickup with a George L's PFII model. The wire that came off of the Sho-Bud pickup is not needed. |

Sorry, the last 2 sentences of his question set me on the wrong foot.

Brad,either Jack or me seems to reading your question differently..As I understand your question,the outside of the copper wire coil under the tape you have mentioned,must be soldered to the lead/hot wire..
The coil is supposed to be continuous..In other words the inside or grounded end of the coil soldered to the wire thats goes close to the middle of the pickup bobbin plate..The coil is wound with thousands of turns of very fine copper wire..The outside of the coil is then soldered to the lead wire and then usually covered with tape..
What you will have to do is find the end of the coil that is now broken off..This can be difficult as its very small about .002" or the size of a human hair..There are thousands of turns of it on the bobbin..Be careful not to "dig" around in the coil to much as it is easily damaged..If and when you find the end, resolder it to the lead wire lay it flat and tape it down..good luck

Sorry about the lack of clarity in my posts. I actually referred to to different things. The wire that came loose was off the old Shobud pickup itself. The pickup was removed with two 5 inch pieces of wire attached, one running from a hole in the center of the bottom of the pickup and one running from under the tape surrounding the coil. The wire that attached under the tape came loose.
The other reference to a wire that I made was to a wire that I made myself in order to have the end plate touching the rest of the metal in the guitar. This is an LDG wood neck guitar, and for some reason the end plate is not grounding with the rest(ie, pickup, changer, strings, levers)of the guitar. I can visually see that no actual contact is being made between any of the metal from the end plate and the changer. I just cut a small piece of the spair wire from the old pickup and attached it under the guitar from a screw on the endplate and a screw on the changer. This required no modification at all, just slighley loosening two screws and slipping the wire underneath. It works great as the guitar is as quiet as can be now. |
