    Hello.

    I'm new here. This is my first post.

    I bought this guitar below...it's a SG400 made in Korea (from the serial number).

    I swapped the pickups for a dimarzio paf pro in the neck and 59 in the bridge.

    But i'm having a lot of issues.

    The Seymour website wiring...the pickup is conected with the far right lug...if i do this...there's no sound...i must connect on the middle lug.

    The Bridge tone pickup also stopped working.

    *When i got the guitar....all eletronics were working fine.

    Probably the biggest thing to keep in mind when swapping pickups is that not all manufacturers use the same color coding scheme for 4 wire pickups. Here's a decent chart I found:

    http://www.proaudioland.com/wp/wp-content/uploads/2014/06/color_codes.jpg

    I'm guessing that will explain the wiring issue with the neck pickup.

    Did the bridge tone control stop doing anything or the bridge pickup? Either way, if it was working previously, it'll likely come down to either a mistake in how things were wired or the pot / capacitor got too hot and was cooked. Go back through all the wiring connection changes you made and ensure they are soldered nicely.

    If it still doesn't work, posting pictures of the wiring might help...

    Thank you!

    Still...nothing.

    Both pickups are only working when they're connected to the middle lug.

    No tone control...(i guess no volume either)

    I did...re did....and re re did all the wiring...nothing.

    Did you replace the pots in your re re re doing it all ? If not it sounds like you might have fried someof them.

    This might help... bucLvlA.jpg

    Also, check for cold solder joints.

    Dead on!

    I fried both pot. Checked with multimeter.....replaced...

    With a quick test...looks like it's all fine.

    I only found one 500k to buy...as i already had a 250k..installed it connected to the bridge.

    Everything works now!

    Thank you!

    & how does it sound? Any improvement? Do you have the tone you were after?

    It sounded awesome!


    Both (Dimarzio paf pro and Seymour 59) are great

    But i think i'm looking for something hotter than the 59'...the paf pro at the neck...requires something hotter...
