volume pot: almost no sound at max volume, pot tests OK

[shoggoth]

Rewired my guitar from EMGs to JB-bridge/Jazz-neck, 500k pots and now for the neck humbucker, when the volume pot is turned all the way up, the volume practically cuts all the way out. Also, the volume in general is very low compared to the bridge humbucker. Bridge sounds great, and everything works as expected.

I thought I just fried the pot, but then I bought a second push-pull type pot with a tab for the ground, very careful soldering, and the exact same result.

Im a totally noob at wiring/soldering, but just seems strange that it happened twice. I also wired the humbucker straight to the jack and that sounds perfectly fine (very hot).

I have a multimeter and tested the first screwy pot - one end on the input, other on the output, and volume all the way reads 0, all the way down reads .518 M, then in the middle it jumps to 139 K. Any advice from someone with some wiring smarts?

its not the pot
do you have one volume and one tone?

or separate volumes for each pickup?

you may have something miss wired or shorted on the switch

2 humbuckers, 2 volumes, 2 tones and a 3 way switch

Photos, please. It is probably a simple oversight.

What type of selector switch and in what location? There are several things that could have gone wrong in this area.

Which schematic diagram did you follow?

Did you ground the wrong lug on the pot?

Nope - but I figured it out... the ground soldering on the back of the tone pot didn't look so great, so I just let it flow a little more and tested, and now the neck humbucker is loud like it should be! Thanks all!
