    Folks,
    I remade the electronics to my LP replica, basically an Epiphone.
    I installed two 57 left the original import switch and put a Crazy Part wiring.
    The problem is the bridge tone doesn't work.
    Before to put everything in the guitar I checked the pickups, both working, the pots, working as well.
    The only thing I haven't checked because I didn't find this problem yet, is the bridge PAF phase.
    Anyways the neck PAF works fine while for the bridge one the volume pot works, the tone doesn't.
    The wiring is correct, so I have no idea what might be. I also though that even if the bridge PAF is out of phase, it shouldn't involve the tone pot working or not.
    I post some pics to show you the wiring. I left the wires a little long to try everything first.
    Thanks for any help IMG_20170921_194640.jpg IMG_20170921_194658.jpg IMG_20170921_194913.jpg IMG_20170921_195003.jpg IMG_20170921_195059.jpg

    Looks like your cap might be grounding out against you ground wire.

    Damn! You're a genius Al. I was checking everything, I also checcked the wires but I haven't noticed that one. In fact it was slightly touching. I moved it and it's solved. Thank you

    I've had that happen to me before, so, it's no big deal. Glad I could help. I just put a new Volume pot in my Junior, only to find out I had a bad solder joint at the pickup lead and pot joint.

    AR, cap is soldered to the outer lug tone pot and the middle volume one. It's a 50s

    NP, Ivan.
    EG00, usually a paf doens't have the hum of a single. I had a Burny in the past and it did have the shielding in the cavity.
    Though this one is silent as a mute.

    My first attempt to do the 50's wiring, I couldn't figure out why there was so much hum... I removed the harness and pots altogether, covered the cavity and back cover with copper shielding.. Hum is gone...

    You have the wire coming from the bridge and going to one of the pot for the ground, right?
