    Thanks in advance for any help!

    I recently refinished and switched out the pickups of my ‘80 SG Firebrand. Pickups are Fralin P-92’s. The bridge is a 3-wire lead, the neck is a braided single wire. The issue is... the only way I get sound is to touch the neck pickup and the 3-way switchcraft jack. I have zero clue how to start thinking about this.. here’s a photo. Any help would be great! Thank you. 18B488D9-02AE-417B-A21A-481036004A40.jpeg

    The bits we can see look to be right. Better detail on the switch and jack, maybe?

    I'm having trouble faulting any of that. If you have a meter, check that all the bits that look connected really are. And check that the switch is actually switching. They can go bad.

    Possibly. When you say the sound is only there when you touch bits, do you mean just touch, or are you maybe pushing a bit and moving something?

    no, just touching the neck pickup and threads on the 3-way switch.

    Am I crazy or is the pickup wire in the middle of the switch here?

    If it were mine I would unwire it and start again, paying great attention to tidiness and good soldering. I think you might save a lot of time by taking it to a tech. This is hard to chase on the Internet/

    If it's any help, this is my '79 The SG, which should be identical to your Firebrand...

    Here is the replaced wiring in my Firebrand SG. It is identical to the wiring in Chuteboxehero's The SG.

    With the risk of sounding autistic, I don't see a bridge ground going into the hole where the pickup wires go, as opposed to in the other pics posted here. Are you sure there is one?

    There should be one. It would come in through the same hole as the 2 pickup leads. If it's not there that may account for your problem?

    No it will cause a buzz but it wont stop the guitar working.

    Thou speaketh the truth, I just figure no harm in making sure everything is in place.

    You mentioned touching the switch gets it to work which indicates the switch contacts are probably slightly bent outward and not making full contact. That would be a good starting point.

    Need to make certain the contacts on the switch are actually closed (making full contact with each other) and not creating an open circuit.

    Since Firebrand Sg's are in the minority, would there be interest in starting a Firebrand page?
    As there was also a Melody Maker, Lp, the 335 guitars in the series, I'd welcome them also.
    I'm sure some of these guitars have stories. Seriously, I'll take and post pictures of mine for this.
